The purge and trap (P&T) method of analysis has been interfaced with fused silica capillary column gas chromatography. This interfacing has been accomplished without splitting the P&T trap desorption carrier gas.Thus, 100% of the purged compoundsare transferred to the column. The analytes are cryofo
A dual-secondary column comprehensive twodimensional gas chromatograph for the analysis of volatile organic compound mixtures A comprehensive two-dimensional gas chromatograph has been developed that splits the primary column effluent into two secondary columns. The resulting technique, dual-seconda
