COMPACT ALARM SYSTEM Example of Atrazin detection 2,5 Natural Water 1 ppm atrazin doped natural water Atrazin-(1mg.L-1) THE OVERALL CONTEXT SECOMAM and Alès Mines School designed a Compact Alarm System called STAC dedicated for this survey. Using an innovative and patented technology, the STAC: : • Estimates the Organic Matter (COD, BOD, TOC), the TSS level and measures the nitrate concentration. • Checks and detects undesirable substances (Pesticides, aromatic hydrocarbons..) PRINCIPLE Most of macro pollutants and mainly Organic Matters, TSS and Nitrates absorb in a specific way in the UV light spectrum. By measuring the sample absorbance in the specific area of the UV spectrum, the STAC records the spectral profile of the sample, a true numerical picture of the water qualit
