Glycol CHEMets Refill

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 to monitor glycol recycling operations. The Purpald-Periodate Method Reference: Purpald® developed by Aldrich Chemical Company. Fritz, James S. and Schenk, George H., Quantitative Analytical Chemistry, 4th ed., p. 277 (1979). In the colorimetric chemistry, periodic acid oxidizes ethylene glycol and/or propylene glycol to formaldehyde, which reacts with Purpald in alkaline solution. Test results may be expressed in either ppm (mg/L) ethylene or propylene glycol. Correction factors are supplied with all kits to convert to the alternate glycol form. This test requires much less time to perform and involves fewer manipulations than the standard chromotropic acid procedure. Shelf-life: five months. We recommend stocking quantities that will be used within four months. Kit comes in a plastic case and contains everything needed to perform 30 tests (except distilled water): Refill, Comparator, Activator Solutions, 25 mL sample cup, sample cup top, and instructions. Range: 1-15 & 10-150 ppm ethylene glycol (EG) (up to 30,000 ppm EG or 60,000 ppm propylene glycol w/ A-0188 Accessory) MDL: 1 ppm Method: Purpald-Periodate
