Abstract

The present invention discloses a general sample injector, comprising a sample injection port mechanism, a sample injector shell, a vaporizing chamber, a heater, a temperature control unit, a carrier gas channel, a septum purge channel, a flow splitting channel, a coolant channel, a multichannel flow control valve and a temperature control unit. The general sample injector, equivalent to a “programmed temperature vaporizer” injector combining splitting/no splitting with cold column head sample injection, gives full play to the advantages of various sample injection modes, overcomes a plurality of disadvantages, and has higher practicability and better flexibility.
