Reflectoquant® Chlorine Test, Catalog No. 16896/1 1. Method Chlorine oxidizes an organic compound forming a violet dye, the concentration of which is determined reflectometrically. 2. Measuring Range and Number of Determinations Measuring Range1) Number of Determinations 0.5 - 10.0mg/l Cl2 50 1) for measurement of concentrations > 10.0 mg/l Cl2 see section 6 3. Applications This test measures only free, active chlorine. Sample Material: Drinking water Wastewater Disinfectant solutions Aqueous solutions 4. Influence of Foreign Substances This was checked - in the case of interfering ions up to concentrations of 1,000mg/l - in solutions containing 5 mg/l Cl2. The concentrations of foreign substances given in the table lie below the limit at which the determination is interfered with: Concentrations of Foreign Substances in mg/l or % Ca2+ 500 Fe2+ 0.1 I2 0.1 Cl- 1,000 Fe3+ 100 H2O2 0.1 CN- 0.5 Mn2+ 100     CO32- 100 NO2- 0.5     CrO42- 100 NO3 1,000     Cu2+ 1,000 SO32- 10     5. Reagents and Auxiliaries The analytical test strips are stable at least up to the date stated on the pack when stored in the closed tube at +2 to +8°C. Package Contents: Tube containing 50 analytical test strips Bar code strip 1 bottle of reagent Cl2–1 1 bottle of reagent Ca–2 1 test vessel Other Reagents: EM Quant® Chlorine Test, Cat. No. 10043, measuring range 4-120mg/l Cl2 pH indicator strips non-bleeding, Universal indicator pH 0-14 Cat. No. 9590 Titristar® Sodium hydroxide solution 1 mol/l Cat. No. SX0607H Titristar® Hydrochloric acid 1 mol/l, Cat. No. HX0603D 6. Preparation Check whether the chlorine content is within the measuring range Use the EM Quant® Chlorine Test as a guide. Samples containing more than 10mg/l Cl2 must be diluted with distilled water. The pH must be within the range 5-10. Check with Universal Indicator Strips. If pH is lower than 5, add sodium hydroxide solution dropwise; if greater than 10, add hydrochloric acid dropwise. 7. Procedure Observe the instructions for the RQflex Reflectometer. The following applies to the Chlorine Test: Measurement procedure A. Stored reaction time: 15 sec. Rinse the test vessel several times with the pretreated sample solution (15-30°), then fill to the 10-ml mark. Add 5 drops of reagent Cl2–1 and swirl. Remove 1 analytical test strip and immediately reclose the tube. Press START button on reflectometer and – this is imperative – at the same time immerse both reaction zones of the test strip in the measurement solution for approx. 2 sec. Vigorously shake off excess liquid from the test strip. As soon as the beeper sounds (5 sec. before end of reaction time), insert the test strip all the way into the strip adapter with the reaction zones facing the display. Read off the result from the display in mg/l Cl2. The result is automatically stored. Note: If the test strip is inserted into the adapter after the reaction time has expired, renewed depression of the START button may result in a false reading of the chlorine concentration. At the end of each workday, cleanse the strip adapter thoroughly with water or ethanol Purchase Chlorine Test Strips 0.5-10 ppm Reflectoquant 1 PK *Requires RQflex 2 EMD# 16950-1 Gallade Part#: 16896 Mfr Part#: 16896-1 Brand: EMD Chemicals EM Science Container: 1 PK of 50 Strips Other products in the category Chemicals for Laboratory / Test Kits/Strips: Alcohol Test Strips 50/each Reflectoquant 1 EA *Requires RQflex 2 EMD# 16950-1 -- Aluminum Test Strips 10-250 ppm EM Quant (1 PK of 100) HAZMAT fee incl -- Aluminum Test Strips 5-50 ppm Reflectoquant 1 PK *Requires RQflex 2 #16950-1 HAZMAT fee incl -- Ammonium Test Strips 0.2-7.0 ppm Reflectoquant 50 PK *Req RQflex 2 #16950-1 HAZMAT fee incl -- Ammonium Test Strips 10-400 ppm EM Quant (1 PK of 100) HAZMAT fee incl -- Ammonium Test Strips 20-180 ppm Reflectoquant 1 PK *Req RQflex 2 EMD# 16950-1 HAZMAT fee incl -- Ammonium Test Strips 5.0-20.0 ppm Reflectoquant 1 PK *Req RQflex 2 #16950-1 HAZMAT fee incl -- Arsenic Test Strips 0.01-0.5 ppm EM Quant (1 PK of 100) HAZMAT fee incl -- Arsenic Test Strips 0.1-3.0 ppm EM Quant (1 PK of 100) HAZMAT fee incl -- Ascorbic Acid Test Strips 25-450 ppm Reflectoquant 50 PK *Requires RQflex 2 EMD# 16950-1 -- Ascorbic Acid Test Strips 50-2000 ppm EM Quant (1 PK of 100) -- Blank Test Strips Reflectoquant 50 PK *Requires RQflex 2 EMD# 16950-1 -- Calcium Test Strips 10-100 ppm EM Quant (1 PK of 60) HAZMAT fee incl -- Calcium Test Strips 2.5-45 ppm Reflectoquant 1 PK *Req RQflex 2 #16950-1 HAZMAT fee incl -- Carbonate Hardness Test Strips 70-425 ppm EM Quant (1 PK of 100) -- Chloride Test Strips 500-3000 ppm EM Quant (1 PK of 100) -- Chlorine Test Strips 4-120 ppm EM Quant (1 PK of 100) HAZMAT fee incl -- Chromate Test Strips 1.0-45.0 ppm Reflectoquant 1 PK *Req RQflex 2 #16950-1 HAZMAT fee incl -- Chromate Test Strips 3-100 ppm EM Quant (1 PK of 100) HAZMAT fee incl -- Cobalt Test Strips 10-1000 ppm EM Quant (1 PK of 100) -- colorpHastŪ pH Test Strips (non-bleeding), PH Variety Pack, 700181 (13 packs of 100) -- Copper Test Strips 10-300 ppm EM Quant (1 PK of 100) -- Copper Test Strips 5-200 ppm Reflectoquant 1 PK *Requires RQflex 2 EMD# 16950-1 -- Cyanide Test Strips 1-30 ppm EM Quant (1 PK of 100) HAZMAT fee incl -- EM Quant Blank Test Strips (1 PK of 100) -- Fixing Bath (Silver) Test Strips 0.2-5.0 g/l Reflectoquant 1 PK *Requires RQflex 2 EMD# 16950-1 -- Fixing Bath (Silver) Test Strips 0.5-10 g/l EM Quant (1 PK of 100) -- Formaldehyde Test Strips Kit 10-100 ppm EM Quant (1 PK of 100) HAZMAT fee incl -- Glucose Test Strips 1-100 ppm Reflectoquant 50 PK *Requires RQflex 2 EMD# 16950-1 -- Iron Test Strips 0.5-20 ppm Reflectoquant 1 PK *Requires RQflex 2 EMD# 16950-1 -- Iron Test Strips 20-200 ppm Reflectoquant 1 PK *Requires RQflex 2 EMD# 16950-1 -- Iron Test Strips 3-500 ppm EM Quant (1 PK of 100) -- Lactic Acid Test Strips 1-60ppm Reflectoquant 1 PK *Requires RQflex 2 EMD# 16950-1 -- Lead Test Strips 20-500 ppm EM Quant (1 PK of 100) -- Lipase Test Strips 10-400) Reflectoquant 1 EA *Req.
