From product description “TOC-VCSN is designed and configured for analysis of wastewater, drinking water, pharmaceutical water, ground water, surface water, saline water, domestic, and industrial wastewater. This instrument meets or exceeds all specifications according to Standard Methods 531B, Environmental Protection Agency Methods 415.1, EPA SW-846 Method 9060A, ASTM 2579, and Clean-In-Place TOC application. The TOC-VCSN utilizes the approved Platinum catalyst, 680-degree Celsius combustion technique to oxidize aqueous samples. The combustion type TOC eliminates salt interferences and ensures complete oxidation even with high molecular weight compounds, suspended particles, and refractory compounds. The system incorporates a Non-Dispersive Infrared (NDIR) detector for maximum sensitivity and durability. The detection limit is 50 ppb while the recommended sample concentration is 300 ppb to 25000 ppm. The TOC analyzer is capable of measuring Total Organic Carbon (TOC), Non-purgeable Organic Carbon (NPOC, Total Carbon (TC) and Total Inorganic Carbon (TIC or IC)The TNM-1 utilizes a chemiluminescence detector to measure Total Nitrogen in the range of 50 ppb to 4000 ppm.
