LCK Reagent Set measures phenols in wastewater, exhaust air, petroleum products, glass and mineral fibres, hardboard, coke, oil shale, hazardous waste, town gas, coal products, tar, asphalt and bitumen.
LCK346 Cuvette test (13mm) measures 5-50 mg/L and 20-150 mg/L phenols in wastewater, exhaust air, petroleum products and other liquids and products. The product uses 4-aminoantipyrine method (ISO 6439-1990, DIN 38409 H16). Article LCK346 may be used for 24 tests. The product can be evaluated with the following instruments: DR3900, DR6000, DR1900, DR2800, DR3800 and DR5000.
For sample analysis containing 5-50 mg/L phenols, pipette 2.0 mL of sample in the sample-cuvette. For analysis of the sample with 20-150 mg/L phenols, add 0.4 mL of collected sample. Close and invert the cuvette a few times. Drip 0.4 mL of solution A using pipette, close the cuvette with DosiCap B and invert the cuvette content several times. Insert the zero-cuvette into the cell holder of the spectrophotometer and select the program. Remove the zero-cuvette and evaluate the sample cuvette. In the presence of oxidizing agent ortho- and meta-substituted phenols form colored complexes with 4-aminoantipyrine (AAP). Larger concentration of cobalt, iron (III), chromium (III), and sulphide may cause high-bias results (see manual for detailed information regarding interferences).
LCK346 storage conditions are between 2 °C and 8 °C (refrigerated).
