✦ Synopsis

The inlet system in Figure 1 proved to be efficient for injecting a wide-bore fused silica column with a lipid solution. The column inlet liner was instrumental in trapping most of the fat thus preventing the small amount of packing material and retention gap from becoming grossly contaminated. The chromatography of the system deteriorates after many injections of a lipid extract, but is restored after changing the septum, column inlet liner, and glass wool at the top of the packing material. The system is easily maintained by changing these items. The small amount of packing materlal and low column bleed allows the system to equilibrate quickly as compared to packed column.

4 Conclusion

This report demonstrates that a wide-bore fused silica capillary column with modified inlet can be used as a substitute for a packed column in the analysis of chlorinated pesticides in a lipid extract.
