MSDS (Material Safety Data Sheet)

Reflectoquant® Ammomium Test, Catalog No. 16899/1 1. Method NH4+ ions react with a chlorinating agent to form monochloramine. This in turn reacts with a phenol compound to form a blue indophenol derivative, the concentration of which is determined reflectometrically. 2. Measuring Range and Number of Determinations Measuring range1) Number of Determinations 5.0-20.0mg/l NH4- 50 1) measurement of concentrations > 20mg/l NH4+ see section 6 3. Applications Sample Material: Wastewater Soils and fertilizers 4. Influence of Foreign Substances This was checked - in the case of interfering ions up to concentrations of 1,000 mg/l - in solutions containing 10mg/l NH4+. 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 % Al3+ 1,000 Ascorbate 100 BO33– 1000 Br– 1,000 Ca2+ 1,000 Citrate 1,000 Cl– 1,000 CN– 1 CO32– 1,000 Cr3+ 100 CrO42– 100 Cu2+ 100 Fe2+ 10 Fe3+ 100 K+ 1,000 Mg2+ 1,000 Mn2+ 100 Ni2+ 1,000 NO2– 50 NO3– 1,000 Oxalate 1,000 PO43– 1,000 SO32– 100 Tartrate 1,000 EDTA 1,000 Anionic surfactants1) 1,000 Cationic surfactants2)1,000 Nonionic surfactants3) 100 H2O2 10 Na2SO4 5% 1) tested with Na-dodecyl sulfate 2) tested with N-cetylpyridinium chloride 3) tested with polyvinylpyrrolidone 5. Reagents and Auxiliaries Please Note the Warnings on the packaging materials! 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.

Preparation Check whether the ammonium content is within the measuring range Use the EM Quant® Ammonium Test as a guide. Samples containing more than 20.0mg/l NH4+ must be diluted with distilled water. The pH must be within the range 4-13. Check with pH indicator strips. If pH is lower than 4, add sodium hydroxide solution dropwise; if greater than 13, add sulfuric acid dropwise. 7. Procedure Observe the instructions for the RQflex Reflectometer. The following applies to the Ammonium Test: Measurement procedure A. Stored reaction time: 240 sec. Rinse the test vessel several times with the pretreated sample solution (20-30°C). Then fill to the 5-ml mark. Add 10 drops of reagent NH4 - 1 and swirl. Add 1 level blue microspoon (in the cap of the NH4-2 bottle) of reagent NH4 -2 and swirl to dissolve. Remove 1 analytical test strip and immediately close the tube. Press START button of the reflectometer and - this is imperative - at the same time place the test strip in the measurement solution for 4 minutes. 10 seconds before end of reaction time, remove the test strip from the solution and vigorously shake off excess liquid. Immediately 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 NH4+. The result is automatically stored. Notes: 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 ammonium concentration. At the end of each workday, cleanse the strip adapter thoroughly with water or ethanol. 8.
