Free Chlorine, Total Chlorine, and ‘Free and Total Cl’ Tests

9

Palintest’s chlorine sensors can be used to measure free and total chlorine simultaneously. On Kemio, select either free chlorine or total chlorine to display a single result, or “free & total” to measure and display both parameters.
When using labels with the free and total test, labels set for both free chlorine and total chlorine are listed. The selected label limits apply only to the parameter they were set for in the configuration menu.
Four different sensor types can be used to measure chlorine:
CLO sensors are used for lower concentrations of chlorine. · 0.02 mg/L – 10 mg/L of free chlorine · 0.02 mg/L – 75 mg/L of total chlorine
CHR sensors are used for higher concentrations of chlorine at higher temperatures · 0.1 mg/L – 25 mg/L of free chlorine (5 °C – 25 °C) · 1 mg/L – 500 mg/L of total chlorine (5 °C – 30 °C)
CLT sensors are used for higher concentrations of chlorine at lower temperatures (2 °C – 15 °C) · 0.1 mg/L – 25 mg/L of free chlorine · 1 mg/L – 500 mg/L of total chlorine
FHR sensors are used for high range free only chlorine · 0.1 mg/L – 100 mg/L of free chlorine (2 °C – 20 °C)

Care Points
If chlorine dioxide is present in solution, it may interfere with the chlorine reading. Use the degassing step from the chlorite test to produce a chlorine dioxide-free solution. Ensure the vessel is washed with water between each test.

10

Results

Free chlorine and total chlorine tests display one parameter each. The free and total test result screen displays both results. The data log stores one entry for each test, requiring twice as much space in memory.

214337

Chlorite Test

24

The chlorite test method involves three separate measurements of various chemical combinations in the sample, followed by some calculations to determine the total chlorite concentration. The test procedure must be followed carefully to ensure the chemical reactions and measurements occur correctly.
A chlorine dioxide measurement forms a part of the chlorite test. However, in the chlorite test type, only labels and limits for chlorite can be selected.
Care Points
· The chlorite test uses three CDX sensors. These must all be from the same batch of sensors. If sensors from different batches are used, it may produce inaccurate results. · If there is chlorine present in the sample, use glycine reagent during the first CDX measurement. If there is no chlorine present, skip the glycine step on p. 20. · Chlorine dioxide is a volatile chemical that leaves a sample very easily. Perform the first test quickly after taking a sample for an accurate measurement. Do not agitate the sample. · If the chlorite test method is interrupted, or if an error occurs partway through the test procedure, the entire test must restart from the beginning to ensure accurate results. · Use separate vessels for the first CDX test before the degassing step, and the second and third tests with CR-1 and CR-2. Do not mix up the two vessels. · Do not let the kit stay wet. Trapped humidity could damage the kit components.

25

Results

The chlorite results screen displays two readings: the calculated chlorite result and the chlorine dioxide result measured by the first sensor.
The chlorite test method displays the concentration of chlorine dioxide in units of mg/L or ppm ClO2, and the concentration of chlorite in units of mg/L or ppm ClO2-.

Arsenic Testing ­ Critical Care Points

44

4
3
2
1
If the sample is turbid (cloudy) then it will need to be filtered to avoid blocking of the ion exchange cartridge. This can be done simply by inserting a particulate filter to the syringe in front of the ion exchange cartridge.

Samples that have been

acidified must be neutralized

before analysis. Acceptable

pH

range is pH 4 – 7.

Ensure that sample is within

10°C

35°C the temperature range

10°C – 35°C.

Always store the ion exchange cartridge in the tube it is supplied in.

45

Darkening of the inlet end of the ion exchange cartridge is normal with some types of water. If this color extends the entire length of the filter then it should be discarded.
Speciated Arsenic requires two sensors to be used during the test procedure. For valid results, these two sensors must have the same batch number.

Check and adhere to all local regulations regarding the disposal of the sensors, ion exchange cartridge and sample water.

46

Results
At the end of the countdown, the test results will display on screen. The number of results displayed depends on the test type.
Disinfection test results are displayed in mg/L or ppm. Metals tests results are displayed in µg/L or ppb.

Dilution
If a label with a dilution factor was used during the test, the factor will have applied to the number on screen. For example, if a 50mg/L solution was diluted 5X and measured by Kemio using a label with a 5X dilution factor, the result displayed on the screen will be 50mg/L.
It is critical that the correct dilution is performed when a label with a dilution factor is used.

47
No Limits
If no label or a label with no limits was used during testing, the page title will be DETAILS on a blue background.

Limits
If a label with limits was used, either a green PASS or a red FAIL will be displayed at the top of the screen. This is simple traffic light system enables a quick and clear decision by the operator.
