Title:
質量分析装置の機差補正方法
Document Type and Number:
Japanese Patent JP7364086
Kind Code:
B2
Abstract:
A method for calibrating a difference in signal intensity ratio between machines in mass spectrometry, the method comprising the steps of: measuring a calibrant containing not less than two calibration substances by a mass spectrometer to obtain a signal peak of each of the calibration substances; determining a signal peak intensity ratio of, relative to a signal peak intensity of one calibration substance of the not less than two calibration substances, a signal peak intensity of another calibration substance; determining a calibration formula from the signal peak intensity ratio; measuring a sample containing not less than two analyte substances by the mass spectrometer to obtain a signal peak of each of the analyte substances; determining a signal peak intensity ratio of, relative to a signal peak intensity of one analyte substance of the not less than two analyte substances, a signal peak intensity of another analyte substance; and calibrating the signal peak intensity ratio of the analyte substances using the calibration formula.
