METHOD FOR ADJUSTING PRESSURE SENSOR AND LIQUID CHROMATOGRAM

The inspection and adjustment of the pressure sensor can be easily performed without adding a complicated mechanism. Therefore, in a liquid chromatography device, a first output value P1 of a pressure sensor 107 measured by setting a flow path in an atmosphere open state or setting a first chromatographic column 110 not filled with a filler in a chromatographic column setting unit 104 is acquired; a second output value P2 of the pressure sensor measured by disposing a second chromatographic column 111 having a known pressure resistance Ps in the chromatographic column disposing unit is acquired, and the gain of the pressure sensor is updated using the first output value P1 and the second output value P2. 能够不追加复杂的机构而容易地执行压力传感器的检查和调整。因此，在液相色谱分析装置中，取得使流路成为大气开放状态或者在色谱柱设置部(104)设置未填充填充剂的第一色谱柱(110)而测定出的压力传感器(107)的第一输出值P1，并取得在色谱柱设置部设置具有已知的压力阻力Ps的第二色谱柱(111)而测定出的压力传感器的第二输出值P2，使用第一输出值P1以及第二输出值P2来更新压力传感器的增益。
