Abstract: A pressure control valve is provided with a pressure control block. The pressure control block has a pressure control block having an opening portion provided on one outer surface, a pressure control surface provided as a plane at a bottom portion of the opening portion, and two internal channels having openings at the respective end portions of the pressure control surface. A sheet-like valve body having elasticity and arranged so as to cover the pressure control surface is provided in the opening portion of the pressure control block. A valve body driving portion is provided on a side opposite to the pressure control surface with the valve body interposed therebetween that adjusts an amount of a gap between the valve body and the pressure control surface by pressing the valve body in a direction perpendicular to the pressure control surface. The pressure control surface has higher hardness than a hard material.

Abstract: A shift of mass axis that occurs when the temperature of a vacuum container consisting of a vacuum chamber (15) and IT block (16) or that of a TOF power unit (20) for applying an ion acceleration voltage is changed, is respectively measured beforehand, and parameters expressing a transfer function based on its response are stored in a transfer function memory (24). During an analysis, a mass shift predicting operation section (25) estimates the current shift length of the mass axis from the current temperatures of the IT block (16) and TOF power unit (20) obtained by first and second temperature sensors (34 and 35) as well as from the two transfer functions stored in the memory (24). A mass shift correcting section (29) corrects the mass axis of the mass spectrum according to the estimated shift length.
