LCS360 Cuvette test (13mm) measures 0.02-0.8 mg/L Zn and 0.024-0.96 mg/L in wastewater, drinking water and other liquids. The product uses PAR method. Article LCS360 may be used for 24 tests. LCK360 reagent set is compatible with DR1900, DR3900 and DR6000. It is recommended to use Crack-Set LCW902 for total zinc digestion.

Mix 2.5 mL sample and 0.2 mL solution A in the sample cuvette. Pipet 2.5 mL distilled water and 0.2 mL solution A in the blank cuvette. Screw the cap onto sample cuvette and blank cuvette in the upside-down position. Insert the blank value cuvette into the cell holder of the spectrophotometer. Remove the blank value cuvette and insert the sample cuvette. Zinc ions are forming water-soluble orange-red-colored complex with 4-(2-pyridylazo)-resorcin (PAR) at pH 6-11. It is recommended to consider the reaction time for accurate testing results (see manual for detailed information regarding reaction time). The water sample pH is required to be pH 2.5-11. The recommended temperature of the water sample and reagents should be 15-25 °C (59-77 °F).

For long-term storage of the sample, it is required to decrease the pH of the wastewater, drinking water or other liquid sample by adding nitric acid. The required pH of the sample is pH<2. The sample must be transported and stored in glass, polyethylene or borosilicate glass vessel. LCS360 reagent kit storage conditions are between 15 °C and 25 °C.
