A method for evaluating a mass spectrometry device includes: by a mass spectrometry device, performing mass spectrometry of an ester of phthalic acid and detecting a plurality of types of ions produced by dissociation of the ester of phthalic acid; and obtaining information concerning whether the mass spectrometry device is in a state suitable for analysis, based on a ratio of intensities of the plurality of types of ions detected.

Method for evaluating mass spectrometry device, method for calibrating mass spectrometry device, analysis method, mass spectrometry device, and mass spectrometry reagent

An uploading computer, a host computer and a viewing computer are interconnected through communication lines. The host computer hierarchizes software information received from the uploading computer by field, category and software product to be stored in software information memory. In response to search information inputted from the viewing computer, the software information is displayed as search results on the viewing computer. The software information hierarchized in the order of field, category and software product is retrieved quickly and displayed immediately to browsed efficiently.

A tubular insert with a small internal volume is disposed inside the vaporization chamber at the inlet of a capillary column of a gas chromatograph such that the sample with a solvent injected into the vaporization chamber is carried by a carrier gas through the insert into the column. The internal volume of the insert is such that the retention time of the carrier gas through the insert is less than 4 seconds. A heater is controlled to maintain the temperature inside the vaporization chamber within a specified range above the boiling point of the solvent as the sample is injected into the vaporization chamber, and this temperature is subsequently raised to a final temperature above the boiling points of the components to be analyzed. The carrier gas pressure is temporarily increased for better efficiency as the sample is injected.
