Targeted testing for total organic carbon in drinking water samples. TOC analysis measures the concentration of organic molecules—those with carbon-hydrogen bonds—to provide a broad assessment of organic contamination. While nearly all water contains some carbon-based material, TOC measurements offer a useful metric for evaluating contamination from natural substances, insecticides, herbicides, and other agricultural or industrial chemicals. This analysis is commonly used in pharmaceutical and industrial applications, and can also detect organic contamination from nearby industrial spills or leaks that may enter drinking water supplies. The kit includes all required materials for proper sample collection and certified laboratory testing. Results provide detailed, quantified analysis of total organic carbon content.(1) 250 mL bottle(1) 500 mL bottle(2) 40 mL vials(1) 50 mL plastic beaker(2) Chlorine test strips (1 free & 1 total)(1) Chlorine color comparator card(1) Sorbent Material
