Monitoring for Organic Contaminants in Boiler Water Condensate

In boiler water condensate the concentrations of organics are low, typically in the range of 0 – 15 mg/l and are measured between the condenser and the return condensate line. TOC analysis has been available for many years as an on-line measurement predominately using three different methods. - Molecular Absorption at UV 254 nm.
