Hach will demonstrate an immunoassay test kit for PCBs. Samples, standards and reagents are added to test tubes coated with an antibody specific for PCBs. The concentration of PCBs in a sample is determined by comparing the developed color intensity to that of a PCB standard. The PCB concentration is inversely proportional to the color development; the lighter the color, the higher the PCB concentration. This method is a semi-quantitative screening method which indicates whether the PCB concentration is above or below 1 ppm and/or 10 ppm threshold values.
