System for Analytical Quality Assurance (AQA), consisting of one combined standard/spiking solution and two round robin test solutions. Applicable for the cuvette tests: - LCK153 Sulphate, 40-150 mg/L SO4 - LCK305 Ammonium, 1-12 mg/L NH4-N - LCK311 Chloride, 1-70 mg/L Cl - LCK314 COD, 15-150 mg/L O2 - LCK340 Nitrate, 5-35 mg/L NO3-N - LCK349 Phosphate (ortho), 0.05-1.5 mg/L PO4-P - LCK385 TOC, 3-30 mg/L C Benefits Confidence in your results Continuous documentation of Analytical Quality Assurance measures using the Addista system substantiates the correctness of your water testing results. Less complexity Each Addista standard solution contains several parameters. This reduces the number of bottles with single parameter standards in your lab significantly. Less error sources The Addista solutions are ready-to use with Hach?s LCK cuvette test. Since there is no dilution needed this allows less hands-on-time and eliminates an additional error source when analysing standard solutions.
