Abstract Under similar analytical conditions (gas chromatograph,detector,liquid phase and carrier gas),a 0 53mm i.d.caplillary column coated with Apiezon L will run a sample three times faster than a 2m long and 5% Apiezon L packed column.The 0.53mm capillary gas chromatography avoids the thermal degradation of some pesticides such as phoxim,methyl phoxim,naled and trichlorfon.Conceptually the 10m��0.53mm �� 0.70��m film capillary column is designed to be alternatives to regular 1/8 inch stainless steel or 2mm i.d. glass column,2m long with liquid phase loadings of 3%��5%.
