THE EFFECT OF TEMPERATURE ON GPC FOR THE SEPARATION OF PCBS FROM TRANSFORMER OIL AND SUBSEQUENT ANALYSIS BY GC-MSD

The analysis of PCBs often involves lengthy and expensive cleanup proc edures to remove interferences associated with environmental sample ma trices. Gel permeation chromatography (GPC) has proven to be a useful tool in removing many of these interferences from environmental sample s, especially from difficult matrices such as oils, lipids and sedimen ts. This paper describes the effect of temperature upon the GPC column in separating PCBs from transformer oil and its implication on GC-MS analysis.
