METHOD OF ENHANCING QUANTITATIVE DETERMINATION PRECISION IN CHROMATOGRAPH/MASS SPECTROMETER

摘要

PROBLEM TO BE SOLVED: To provide a method of enhancing quantitative determination precision in a chromatograph/mass spectrometer, capable of using permanently an analytical working curve registered in a database or an analytical working curve prepared at first (in the first time).;SOLUTION: A mass pattern calibration result is corrected to be apparently same based on a mass spectrum of a mass spectrum-confirming standard substance or a mass-calibrating (tuning) standard substance, in an identification quantitative determination method of a chemical substance by the chromatograph/mass spectrometer.;COPYRIGHT: (C)2009,JPO&INPIT
