Free & Total Chlorine Free & Total Chlorine CRMs and RMs for Total and Free Residual Chlorine SnipsTM 0.100 mg/L, dilutes to 50 mL Chlorine Check RM - Amperometric/Iodometric Titration - 0.100 mg/L, dilutes to 200 mL “When we designed our portfolio of Residual Chlorine RMs and CRMs, we wanted them to be really easy to use. We realized that pipetting and cumbersome dilution schemes were impractical in certain water and wastewater testing situations”, said Ewart Morris, Inorganics Technical Manager at NSI Lab Solutions. “To reach this goal, we redesigned the packaging and concentration ranges typically available for chlorine residual reference standards with a focus on ease of use.” QCI-118 . . . . . . . . . . . . . . . . . . 25 Tubes . . . . . . . . . . . . . . . . $50.00 QCI-148 . . . . . . . . . . . . . . . . . 25 Tubes . . . . . . . . . . . . . . . . $50.00 Total Chlorine Accuracy Check RM 1.00 mg/L, dilutes to 25 mL Chlorine Check RM - Amperometric/Iodometric Titration - 1.00 mg/L, dilutes to 200 mL QCI-123. . . . . . . . . . . . . . . . . . 25 Tubes . . . . . . . . . . . . . . . . $50.00 QCI-149 . . . . . . . . . . . . . . . . . 25 Tubes . . . . . . . . . . . . . . . . $50.00 Total Chlorine Accuracy Check RM 2.50 mg/L, dilutes to 25 mL Chlorine Check RM - Amperometric/Iodometric Titration - 2.00 mg/L, dilutes to 200 mL QCI-117 . . . . . . . . . . . . . . . . . . 25 Tubes . . . . . . . . . . . . . . . . $50.00 QCI-150 . . . . . . . . . . . . . . . . . 25 Tubes . . . . . . . . . . . . . . . . $50.00 Our new Chlorine Snips™ are the most convenient reference material for residual chlorine analysis on the market. They require no pipets and no glassware other than the instrument cuvette to prepare. Chlorine SnipsTM are ideal for use at testing points remote from the fixed base laboratory. To use a SnipTM, simply open the tube with a pair of scissors and transfer its contents to your cuvette and bring to volume with reagent water. Ultra Low Chlorine Accuracy Check RM Ampules Our Chlorine SnipsTM and chlorine CRMs are applicable to both drinking water and wastewater testing. Our internal certification protocol includes both total and free residual chlorine with values for both documented on accompanying COA. As always, if you need a different concentration or dilution scheme, please contact us. It will be our pleasure to help.
