Teledyne Tekmar has been the market leader in environmental and drinking water testing for decades, having invented many of the instrumental technologies used in today’s lab.  From TOC drinking water analysis to EPA compendium methods for air, soil and water, Tekmar has the right instrument for your application.

TOC has a long history as being a world-renowned analytical technique to measure water quality during the drinking water purification process. TOC in source waters comes from decaying natural organic matter (NOM) and from synthetic sources. Humic acid, fulvic acid, amines, and urea are types of NOM. Detergents, pesticides, fertilizers, herbicides, industrial chemicals, and chlorinated organics are examples of synthetic sources. Before source water is treated for disinfection, TOC provides an important role in quantifying the amount of NOM in the water source. In water treatment facilities, source water is subject to reaction with chloride containing disinfectants. When the raw water is chlorinated, active chlorine compounds (Cl2, HOCl, ClO-) react with NOM to produce chlorinated disinfection byproducts (DBPs). Many researchers have determined that higher levels of NOM in source water during the disinfection process will increase the amount of carcinogens in the processed drinking water. In the 1970’s TOC analysis emerged as a rapid and accurate alternative to the classical but lengthy biological oxygen demand (BOD) and chemical oxygen demand (COD) tests traditionally reserved for assessing the pollution potential of wastewaters. Today, Environmental Protection Agencies regulate the trace limits of DBPs in drinking water. Recent methods, such as USEPA method 415.3, D/DBP rule, regulate the amount of NOM to prevent the formation of DBPs in finished waters.
