โœฆ Synopsis

The use of silica gel plates and hexane for identification of polychlorinated biphenyls, naphthalenes and terphenyls is discussed . Quantitation of polychlorinated biphenyls is described using a linear, thin-layer chromatographic scanner and'silver nitrate/UV chromogenesis . Sensitivity is o .5 p.p.rn. in muscle tissue, egg and fat with a precision of ยฑ o .05 p .p.m.

A dual-column. gas chromatographic, congener-specific methodology was developed that allows determination of polychlorinated biphenyl (PCB) concentrations in water and sediment samples. The linearity of the detector responses was checked over a range of 1000 at the sub-ppb range of total PCB in the
