The following case studies illustrate the performance
using Sitelab’s UVF-3100C analyzer for testing Polychlorinated
Biphenyls (PCBs). The
analyzer is fitted with optical filters sensitive to the PCB
Aroclors of interest.
However, since PCBs are often found in transformer oils or waste
oils, which may co-fluoresce at the PCB wavelength, the potential
interference of the non-PCB compounds is minimized by calibrating
the analyzer using the PCB concentrations reported by a confirmatory
lab’s GC-ECD method.
