In this paper, an attempt is made to solve the overlap problem of PUFA concentrated fish oil methyl ester peaks using a DEGS packed column. The components of the peaks were examined by GC-MS (reconstracted ion chromatogram and QM+ of a methyl silicone capillary column GC-MS) and a Carbowax 20 M capillary column GC. A comparison was made of the % area of concentrated PUFA-fish oil methyl ester, as determined by the DEGS packed column and Carbowax 20 M capillary column. Hexadecatetraenoic acid (C16 : 4) was found in the linoleic acid (C18 : 2) peak, and henicosapentaenoic acid (C21 : 5) in the peak found between those for icosapentaenoic acid (C20 : 5) and docosapentaenoic acid (C22 : 5). The peak of hexadecatetraenoic acid shifted according to the polarity change in the liquid phases in the DEGS packed column.
