PCB/Chloride
Analyzer
Description
The L2000 PCB/Chloride Analyzer is an instrument used to test for polychlorinated
biphenyls (PCBs) in soil, in transformer oil, and on surfaces. It works by
first adding a chemical to the medium to be tested. The chemical removes all of
the chloride from the PCB molecule. The instrument then measures the amount of
chloride ions.
Because PCBs contain chloride ions, the device is able to quantify the
concentration of PCBs. The instrument converts the chloride reading into parts per million (ppm).
Limitations
and Concerns
The PCB/Chloride Analyzer is sensitive to organic chloride
from any source, not just PCBs. This means that if other chlorinated organic
compounds are present, they will be detected as well. This may limit the
ability of the technique to accurately detect the levels of PCBs.
Polychlorinated biphenyls are a family of chemicals, all of which have
different proportions of chloride ions. The analyzer measures the quantity of
chloride ions in the substance being analyzed. Without knowing which type of
PCB is present, itŐs impossible to know the concentration of PCBs.
Applicability
This analytical device is used to test PCBs in soils and on building
surfaces.
Technology
Development Status
The device is commercially available.
