SpletLPD Lab Services can assess PCBs for a wide range of ionic contamination using Ion Chromatography IC. These include anions, cations and weak organic acids WOAs on printed circuit boards. Ionic contamination on PCB s can lead to serious quality issues. Product reliability can be affected. Lifetimes can be shortened especially in environments ...
SpletThe PCB family has 209 congeners, defined by the position of chlorines on the biphenyl molecules. Gas chromatography (GC) is often used to measure PCB contamination in the environment. The electronegative chlorines on the PCB biphenyl rings show good response in ECD, and so GC-ECD is a key technique for PCB analysis.
