Product Information

Specifications:

• Product Name: II As+3 Low Range As+5 Rapid Arsenic Test Kit
• Part Number: 481301-5
• Number of Tests: 5

About Kit #481301-5:
This test kit is designed to detect soluble inorganic Arsenic (As+3 and As+5) in water samples. It utilizes the patented Modified Gutzeit method, where inorganic Arsenic compounds are converted to Arsine (AsH3) gas through a reaction with Zinc Dust and Tartaric Acid. The Arsine then reacts with Mercuric Bromide on the test strip, resulting in a color change from white to yellow or brown. The kit also includes Ferrous and Nickel salts to accelerate the reaction, and Potassium Peroxymonosulfate as a second reagent to oxidize Hydrogen Sulfide to Sulfate.

Precautions: It is important to work in a well-ventilated area away from fire and other sources of ignition, as Hydrogen gas and Arsine gas are generated during the reaction. All reagents included in the kit are unsuitable for human consumption and should be kept away from children and pets.

US Patent #6696300

ABOUT KIT # 481301-5:

This test detects soluble inorganic Arsenic (As+3 and As+5)

This Arsenic Test Kit provides a safe, simple, and precise way to test for Arsenic from 1 to 10 μg/L. For accurate results when Arsenic value is above 10 μg/L, perform a dilution of the water sample so that the value will read below 10 μg/L. Follow the instructions carefully to get reliable results. All components are supplied in the kit except for a timer and thermometer. This test tolerates up to 2.0 mg/L Hydrogen Sulfide without interference. No interference was found for this test kit for Antimony up to 0.5mg/L. No interference from Iron or Sulfate was found. Higher levels of Hydrogen Sulfide can be corrected for by diluting (only where sensitivity needs are not compromised). There were no interferences from other components typically found in tap water. It is recommended that the water sample be 22ºC – 28ºC. For reference, record the temperature at which the sample was run. Use kit within the shelf life as marked.

About the Patented Reaction (Modified Gutzeit method):
Inorganic Arsenic compounds in the water sample are converted to Arsine (AsH3) gas by the reaction of Zinc Dust and Tartaric Acid. Ferrous and Nickel salts have been added to accelerate this reaction. The Arsine reacts with the Mercuric Bromide on the test strip to form mixed Mercury halogens (such as AsH2HgBr) that appear with a color change from white to yellow or brown. Potassium Peroxymonosulfate (second reagent) is added to oxidize Hydrogen Sulfide to Sulfate.

PRECAUTIONS : Hydrogen gas and Arsine gas are generated during the reaction. Work in a well-ventilated area away from fire and other sources of ignition. All reagents are unsuitable for human consumption and must be kept away from children and pets.

US Patent # 6696300

ATTENTION : Your Arsenic results will be low if step 5 in the The test procedure is not followed carefully. When you position the testing pad over the orifice, you must press down the turret handle very firmly over the testing pad to securely lock the testing pad into position. If the cap is not firmly formed around the testing pad, arsine gas will bypass the testing pad, which results in lower arsenic levels.

WARNING : Hydrogen and Arsine gases are generated during the test. Work in a well-ventilated area away from open flames and other sources of ignition. Review the Material Safety Data Sheet before handling any chemicals.

For better accuracy, we recommend running the test in duplicate.

Test Procedure:

1. For best results, the water temperature should be between 22°C to 28°C. Use a thermometer to verify the temperature of the sample.
2. To the Reaction Bottle, slowly add the water sample to the marked line on the bottle (250mL).
3. Add contents of one Powder Pillow* of First Reagent to the Reaction Bottle. Cap the bottle securely with black mixing cap and shake vigorously for 15 seconds.
4. Uncap the Reaction Bottle; add contents of one Powder Pillow* of Second Reagent . Cap the bottle securely with black mixing cap and shake vigorously with bottle upright for 15 seconds. Allow the sample to sit for 2 minutes to minimize Sulfide interference.
5. While the test is incubating for 2 minutes, prepare the turret cap as follows ( NOTE : The cap and turret must be dry. If the testing pad becomes wet results will be inaccurate):
6. Open the packet and carefully remove the strip. While handling the strip avoid touching the Mercuric Bromide testing pad at one end of the strip.
7. Position either side of the testing pad over the orifice (Figure 1) and press down the turret handle over the pad until it locks into position on the cap.
8. Make certain the red turret with handle is fully closed (as illustrated in Figure 2). The red turret should be pressed level with the top of the cap to ensure all gas passes through the testing pad.
9. To confirm that the testing pad completely covers the hole in the cap, visually inspect the orifice from under the cap. The turret cap is now ready for use in Step 7.
10. Uncap the Reaction Bottle and add contents of one Powder Pillow* of Third Reagent . Cap the bottle securely with black mixing cap and  shake vigorously for 5 seconds.
11. Remove the black cap from the Reaction Bottle and recap securely using the turret cap within 20 seconds. As you screw on the turret cap, be careful not to splash the water or reagents on the testing pad. It is important that the testing pad remains dry during the test. Place the bottle in a well-ventilated area where it will not be disturbed. You should notice numerous small hydrogen gas bubbles generating from the Tartaric Acid and Zinc Dust Reagents.
12. Start the timer and wait for 10 minutes. Reaction generates small hydrogen gas bubbles.
13. After waiting 10 minutes (but no longer than 12 minutes), pull the turret up. Carefully remove the test strip with the testing pad. Flatten the testing pad, if necessary, by gently pressing it between two clean pieces of paper. Use the Color Chart and match the color of the exposed side of the testing pad within the next 2 minutes (colors oxidize when exposed to light). For best color matching use natural daylight, but do not use direct sunlight. The color can be preserved for a short time by returning the testing pad to the packet and keeping it out of light. If using the Quick™ Scan Test Pad Reader, follow the meter’s instructions.
14. Record your result.

Before opening the powder pillow packet at one end, shake the reagent in the packet to the “bottom” so that the reagent will not spill when opening at the “top” of the packet. (Mercuric Bromide strips (Arsenic test strips) will not react with arsine gas if they are wet!

ATTENTION : Soon after testing is completed, decant liquid from the bottle down a drain that is not used for food preparation and flush with water. See comment #4 on page 4. Wet Zinc should be collected and disposed of according to local regulations. Rinse the bottle and the cap with clean water. Shake off any excess water. Do not rinse turret cap. It is best to dry turret cap with a soft tissue or paper towel, especially if you plan to run the next test immediately. Keep the used strips inaccessible to children and pets, and dispose according to local environmental regulations.

INSTRUCTIONS FOR BEST ACCURACY

1. To gain confidence in using this test kit for unknown samples, it is highly recommended that you use the kit on a sample with a known inorganic Arsenic concentration value, or with a sample that has been prepared using an Arsenic standard. By making a “practice run” of the test, you will familiarize yourself with all of the procedures necessary to ensure accurate testing results. Additionally, you will have the opportunity to become familiar with the process of color matching, which will help to ensure accurate test results. ITS suggests the test be run in duplicate for better accuracy.
2. The water sample must not be preserved with Nitric Acid or any other preservation method. Small amounts of strong acids will interfere with the test results; and therefore it is best that the water sample be freshly drawn and run within 24 hours. Some water samples held for over 24 hours may read low. The water sample should not contain any significant amount of buffers. If you are planning to send a duplicate sample for ICP laboratory verification, follow preservation requirements for that sample only.
3. The water and ambient temperature are very important to ensure accurate results. As an example, a water temperature of 15°C can result in the color development on the testing pad to be lighter than the actual Arsenic concentration in the tested sample (a false low reading occurs). When the water is cold, warm water sample to 22°C to 28°C before testing (using a microwave is acceptable). If the water temperature is above 28°C your result may read low (accelerator chemistry reacts too fast). Consideration must also be made for the air temperature when running the test. Best results are from 22°C to 28°C (water and air). The color chart and Arsenic Scan chart are calibrated at 24°C.
4. After the test has been run, try to rinse out the reaction bottle with clean tap water as soon as possible. When the reaction chemicals are allowed to sit in the reaction bottle after the reaction time, the zinc may begin to adhere to the bottom of the bottle. When this occurs, you may need to clean the reaction bottle with a bottlebrush. Another method for zinc removal is to use a 20% Hydrochloric Acid (reusable) rinse. Be sure to rinse the reaction bottle with clean tap water before running the next test.
5. When matching your test strip pad with the colors on the Easy-Read™ color chart, it may be helpful to find a color that is clearly lighter than the test strip pad and make note of it (as an example, we will use a value of 1.5 ppb). Next, find a color that is clearly darker than the test strip pad (as an example, we will use a value of 3 ppb). By defining a lowest and highest possible value range we can assume that the correct color match is 2.0 ppb. If the 2.0 ppb color matches, then you have determined your Arsenic level.
   • In some cases, an exact color match will not be available. Following these easy steps can make color matching more precise. Careful color matching will assure the best possible result.
6. Levels of Hydrogen Sulfide above 2 mg/L can interfere with this test, resulting in elevated Arsenic readings. Our test kit will eliminate up to 2 mg/L of Sulfide interference. To overcome Hydrogen Sulfide levels above 2 mg/L, allow the water sample to sit at room temperature, uncovered and exposed to air for 8 hours (about 50% of the H2S gas dissipates for every 8 hours).
   • Industrial Test Systems, Inc. sells Hydrogen Sulfide detection kits (part # 481197-20) for quick, accurate verification of this interfering ion. The test kit detects levels of 0.3, 0.5, 1.0, and 2.0 mg/L (ppm). The Hydrogen Sulfide test kit contains all components necessary to run the test, and is economically priced at $15.99 for 30 tests.
7. Do not use components from other kits. Interchanging components may result in inaccurate results since each kit is Quality Control released for accuracy with its given components. Some conditions can result in getting an incorrect reading: the presence of Hydrogen Sulfide above 2ppm; color matching in poor lighting conditions; color blindness of operator; and sample temperatures that are high or low.
8. If you have any questions or comments, please feel free to contact our R&D Department at 1-803-329-0162 ext 211 or by email at: [email protected].
9. Record your results and details for future reference.

LETTER FROM THE KIT INVENTOR

Thank you for purchasing our U.S. Patented (# 6,696,300) Arsenic Quick™ II Kit. Our company has trademarked the kits Quick™ because of the short 14 minute time for analysis. The Drinking Water standard of the US EPA and the World Health Organization (WHO) allows a maximum contami-nant level of 10 ppb (μg/L) for Arsenic. The old US EPA level of 50 ppb (μg/L) remains as the maximum contaminant level for many countries in the world.

For several years, Industrial Test Systems, Inc. (ITS) committed a major research & development effort to provide better and safer arsenic test kits. The goal was achieved. The test was made safer by using tartaric acid, instead of strong acids, for the reduction of inorganic arsenic (As+3/As+5) to arsine gas. For these efforts a US Patent was granted for the acceleration of the arsenic detection chemistry by the addition of metal enhancers, iron and nickel salts. This permits

Arsenic field tests to be completed faster. The Quick™ II series of kits use a modified Turret cap which allows detection of arsenic below 10 ppb (μg/L). The reduction reactions utilized in all kits are as follows:

• Zn +2H+ → Zn+2 + H2 (gas) and As4O6 + 12 Zn +24H+ → 4AsH3(gas) + 12 Zn+2 + 6H2O (pH 1.6)

The analysis is performed in a closed reaction bottle (plastic) with an appropriate volume of sample (50 to 500 ml). After the 10 minute reduction reaction, the mercuric bromide strip or testing pad is removed and matched to the color chart or color analyzed by the Quick™ Arsenic Scan instrument. A light yellow to brown color change indicates that arsenic is present. The color intensity is proportionately related to the concentration of arsenic in the sample.

NOTE : ITS test kits detect free inorganic arsenic only. ICP-MS methods detect inorganic and organic arsenic. If organic arsenic is present, ITS kit results can be expected to give lower values when compared to ICP-MS results.

Where precision is important, ITS recommends that you run the water sample in duplicate, since the typical color matching is within one color block. For best precision consider the purchase of our Quick™ Arsenic Scan instrument. This unit is ideal for use with all test kits. Please contact our sales department at 803-329-9712 for more information or to order the Quick™ Arsenic Scan instrument.

Typical shelf life of kits is over 12 months. The kit includes First Reagent (Tartaric acid with iron and nickel salts); Second Reagent (MPS, an oxidizer); Third Reagent (zinc dust); and mercuric bromide strips, which contains about 1mg mercury per strip. After use, the strips should be discarded according to local environmental regulations. Valuable safety information about the kit is in the MSDS literature. As a safeguard to minimize the operator’s exposure to arsine and hydrogen gas, please run all tests in a well-ventilated area away from open flames and other sources of ignition. Arsine gas is highly toxic; and this precaution becomes more urgent if the water sample has high arsenic levels.

Cordially yours, Ivars Jaunakais, Analytical Chemist email: [email protected]
