Claims

[Scope of Claim for Utility Model Registration] 1. The outlet side of a pretreatment mobile phase transport section equipped with a sample injection section, the inlet side and outlet side of a pretreatment column section, the inlet side and outlet side of an analytical column section, and the use for analysis. A flow path switching valve that has a port that connects the outlet side of the mobile phase liquid feeding section, the inlet side of the sample detection section, and the inlet side of the drainage section for both of the mobile phases, and connects each of the above sections in a switchable manner. Then, the flow path switching valve is switched to connect the pretreatment mobile phase delivery section, pretreatment column section, and detection section in this order, and the sample injection section is operated to inject the sample from the start of the injection. elution time setting means for calculating the elution time until the sample begins to elute from the pretreatment column part based on the injection signal and the detection signal; Compare and calculate both signals output from the time measurement means and setting means, and when these two signals match, output a match signal, switch the flow path switching valve again, and switch the mobile phase for analysis. A liquid chromatograph comprising a control means for connecting a liquid feeding section, a pretreatment column section, an analytical column section, and a sample detection section in this order. 2 Claim No. 1 for Utility Model Registration in which the elution time setting means, timing means, and control means are comprised of a microcomputer
Liquid chromatograph as described in section.
