Abstract
A liquid chromatograph mass spectrometer includes a liquid chromatograph unit for performing liquid chromatography, an atomizer having a controllable temperature for heating and atomizing a liquid flowing out of the liquid chromatograph unit during liquid chromatography to produce an atomized liquid, an ionizing device for ionizing the atomized liquid to produce an ionizing sample, a mass spectrometer for analyzing the ionized sample, a storage device for successively storing liquid chromatography conditions and respective atomizer temperatures used for the liquid chromatography conditions for past measurements performed with the liquid chromatograph mass spectrometer, an input device for inputting a current liquid chromatography condition for a current measurement, a retrieving device for retrieving from the storage device a liquid chromatography condition nearest to the current liquid chromatography condition among the liquid chromatography conditions stored in the storage device, and the atomizer temperature used for the retrieved liquid chromatography condition, and an atomizer temperature setting device for setting the atomizer temperature to an optimum temperature for the current liquid chromatography condition based on the retrieved atomizer temperature.
