Claim Text:
1. A method of replacing a septum or glass insert of a gas chromatograph mass spectrometer, the gas chromatograph mass spectrometer comprising: an oven for gas chromatography provided with a housing, a column disposed inside said housing, and a first heater for heating said housing; a sample vaporization chamber provided with a casing having a sample introduction port through which a liquid sample is introduced, a carrier gas introduction port through which a carrier gas is introduced, and a column connection port connected to the inlet end of said column and a second heater for heating said casing; a mass spectrometry part which is connected to the outlet end of said column and has a detector for detecting an ion intensity signal of said liquid sample; a gas supplying part for supplying a carrier gas to the carrier gas introduction port of said sample vaporization chamber; and a control part having an input device for inputting setting content including an analysis temperature; wherein said septum into which the needle of a syringe containing a liquid sample is inserted is disposed in said sample introduction port, said glass insert is disposed for vaporizing the liquid sample inside said casing, and said control part obtains an ion intensity signal from said detector while controlling the first heater, the second heater, and the gas supplying part based on the setting content inputted by said input part; the method comprising:
