CHEMetrics K-4815 Glycol Kit
Product Information
- The K-4815/R-4815 is a testing kit designed to measure the concentration of propylene glycol or ethylene glycol in a sample. It includes various activator solutions and color standards to facilitate accurate testing.
- It is important to read the Safety Data Sheet (SDS) available at www.chemetrics.com before using this product. Safety glasses and protective gloves should be worn during product usage.
Activator Solution Preparation
- Fill the A-4401 Activator Solution bottle to the shoulder with distilled water or add 15 mL of distilled water.
- Add 10 drops of A-4402 Activator Solution.
- Cap the bottle and shake it until the chemical dissolves completely.
- Label the bottle with a 6 month expiration date.
1 – 15 ppm Test Procedure
- Fill the sample cup to the 20 mL mark with the sample to be tested.
- Add 5 drops of A-4400 Activator Solution. Cap the sample cup and shake it to mix the contents well.
- Wait 5 minutes.
- Add 6 drops of A-4401 Activator Solution and 4 drops of A-4402 Activator Solution. Cap the cup and shake it to mix the contents well.
- Place the CHEMet ampoule, tip first, into the sample cup. Snap the tip. The ampoule will fill leaving a bubble for mixing.
- To mix the ampoule, invert it several times, allowing the bubble to travel from end to end.
- Dry the ampoule. Obtain a test result 12 minutes after snapping the tip.
- Obtain a test result by placing the ampoule between the color standards until the best color match is found.
Note: To convert to ppm propylene glycol, multiply the test result by 2.
Modifying Kit Range
The kit range can be modified by performing a sample dilution. For the desired range, dilute the prescribed volume of sample to 20 mL with distilled water in the sample cup. Perform the test procedure (Steps 2-8) with this diluted sample. Multiply the result obtained in Step 8 by the corresponding factor to obtain the glycol concentration of the undiluted sample.
Desired Range, ppm ethylene glycol| Volume of Sample| Sample Measuring Device|
Multiply Test Result by
---|---|---|---
10 – 150 ppm| 2 mL| 3mL syringe (in kit)| 10
20 – 300 ppm| 1 mL| 3mL syringe (in kit)| 20
100 – 1500 ppm| 200 uL| A-0194 & A-0171| 100
200 – 3000 ppm| 100 uL| A-0170 & A-0171| 200
400 – 6000 ppm| 50 uL| A-0193 & A-0171| 400
800 – 12,000 ppm| 25 uL| A-0191 & A-0171| 800
Test Method: Certain aldehydes and alcohols may cause high test results.

This test method is somewhat temperature dependent. For best results, samples
should be less than 40°C.

1 – 15 ppm Test Procedure
-
Fill the sample cup to the 20 mL mark with the sample to be tested (fig. 1).
-
Add 5 drops of A-4400 Activator Solution (fig. 2). Cap the sample cup and shake it to mix the contents well.
-
Wait 5 minutes.
-
Add 6 drops of A-4401 Activator Solution and 4 drops of A-4402 Activator Solution (fig. 2). Cap the cup and shake it to mix the contents well.
-
Place the CHEMet ampoule, tip first, into the sample cup. Snap the tip. The ampoule will fill leaving a bubble for mixing (fig. 3).
-
To mix the ampoule, invert it several times, allowing the bubble to travel from end to end.
-
Dry the ampoule. Obtain a test result 12 minutes after snapping the tip.
-
Obtain a test result by placing the ampoule between the color standards until the best color match is found (fig. 4).

Test Method
The Glycol CHEMets®1 test method employs the Purpald®2/Periodate chemistry3. Periodic acid oxidizes ethylene glycol and propylene glycol to formaldehyde. In a highly alkaline solution, and in conjunction with an oxidizing agent, formaldehyde reacts with Purpald to form a purple colored complex. Certain aldehydes and alcohols will cause high test results.
