R-4815 Glycol

Dissolved Glycol Testing Visual Kit is designed to measure glycol in the range 1-15 ppm & 10-150 ppm

Glycol Information


The K-4815 Glycol CHEMets Visual Kit is visual indicator kit for measuring glycol in water levels from 1-15 and 10-150 ppm.  This device uses the Purpald-Periodate Method for testing. In the colorimetric chemistry, periodic acid oxidizes ethylene glycol and/or propylene glycol to formaldehyde, which reacts with Purpald in alkaline solution. Test results are expressed as ppm (mg/L) ethylene glycol. To convert results to ppm propylene glycol, multiply by 2.

Ethylene glycol and propylene glycol are the primary ingredients in commercially-available antifreezes. They are used with various corrosion inhibitors to protect metal surfaces in cooling water systems. CHEMetrics glycol kits are used to monitor potable waters for glycol contamination originating from glycol in cooling systems. They are also used to detect glycol in storm water effluent and airplane deicing operations and to monitor glycol recycling operations.

Shelf-life of the Purpald Reagent: five months. We recommend stocking quantities that will be used within four months.

The refill kit R-4815 can be purchased for more tests.

How to use the K-4815:

Instructions for Ozone water testing using the K-7404



  1. Fill the sample cup with 20 mL of sample water.Fill the sample cup to 25ml
  2. Add 5 drops of A-4400 Activator Solution, cap the sample cup, and shake gently.
  3. Wait 5 minutes
  4. Add 6 drops of A-4401 Activator Solution
  5. Add 4 drops of A-4402 Activator Solution, cap the sample cup, and shake gently.
  6. Snap the end/tip of the ampoule in the water on the bottom/side of the 25 mL sample cup.Snap the tip of the ampoule on the bottom and side of the sample cup
  7. Mix the contents of the ampule by tipping back and forth a few times.Tip the vacu-vial back and forth to mix
  8. Dry the ampoule and wait 12 minutes for color development.Dry vacu-vial and then insert into the I-2019
  9. Obtain the test result by matching to the corresponding color comparator.
