Abstract
The present invention discloses a chromatographic analysis device based on a multifunctional integrated probe, and a use method of the chromatographic analysis device. The chromatographic analysis device integrates chromatographic sampling, sample injection and separation functions into the integrated probe. Meanwhile, the present invention further discloses a method for performing microsample analysis by the chromatographic analysis device based on the multifunctional integrated probe. The present invention has the main advantages as follows: the device is high in integration level, small in dead volume, simple in structure, convenient to use and particularly suitable for microsample analysis with a small sample amount, provides a new chromatographic sample injection mode for chromatographic analysis, and provides an ideal platform for chromatographic analysis and on-site chromatographic analysis of a trace amount of samples.
