Chlorine Test Kit, Visual Colorimetric Analysis, 0-1 & 1-5 ppm, DPD Method, Chemetrics, Inc., K-2505

CHEMetrics® Colorimetric Chlorine D DPD Test Kit with Reagents for 30 Tests, Range: 0 to 1 and 0 to 5 mg/L (ppm), K-2505

Features:

• D DPD Method (Reference: Developed by CHEMetrics, Inc.)−derived from DPD method
• Well suited for use where biocides and chromate corrosion inhibitors are used simultaneously
• DDPD reacts with free chlorine to form a purple product
• In presence of ammonia or amines, some of the chlorine may exist as combined chlorine
• To determine total chlorine (the sum of free and combined), use the A-2500 Activator Solution (potassium iodide) that is supplied in the kit
• Results are expressed as ppm (mg/L) Cl₂
• DDPD method is also applicable to the direct determination of hypochlorite concentrations in various cleaning preparations and disinfectants prior to their dilution−DDPD compound reacts with hypochlorite ions to form a purple color
• Results are expressed as percent (%) NaOCl
