【Author】 By using two dimension valveless column switching system solvent-cut, heart-cut, back-flush and transfer mode operation can be performed to offer better resolution, shorter analy-tical time as well as protecting the main analytical column. Results are given in packed-packed column, packed-capillary column and capillary-capillary column combination.In addition, a four in one multifunction detector which has FID, ECD FPD and NPDfunctions was developed for identification and determination of complex mixtures. It can beused as a single detector and also a multi-responses detector simultaneously as well. Bothpacked and capillary column have been combined with this new detector for monitoring somespecial compounds in a complex mixture. A new intelligent gas chromatograph with columnswitching system and multifunction detector is now in developing in our institute.
