| Abstract: | Methods of programming temperature and flow rate of carrier gas for to reducing the time of analyte separation on polycapillary columns (PCC) are compared. As was shown, the programming of temperature is accompanied by a change of peak shape, associated with the irregular heating of PCC capillaries. The programming of carrier gas flow rate does not distort the shape of chromatography peaks and does not require long time to return the system to the starting conditions. |
