20110101215 | QUANTITATIVE ANALYSIS METHOD USING MASS SPECTROMETER - In quantitation without using the isotope labeling technique, there is no means to detect the presence/absence and the time region of the occurrence of quantitative analysis-inhibitory factors in data for the analysis, and the reliability of the data for the analysis cannot be evaluated. Also, the error of the data due to the occurrence of the quantitative analysis-inhibitory factors cannot be evaluated. In order to solve the problems, first, an internal standard to be detected simultaneously with a component for the analysis is mixed in a mobile phase or an eluate of a liquid chromatograph; under the condition where no quantitative analysis-inhibitory factors occur, a blank sample is analyzed to acquire a mass chromatogram of ions originated from the internal standard; and the result is stored in a data storage unit. Then, a sample for the analysis is mixed to acquire data for the analysis of the sample; and the intensity of ions originated from the internal standard is compared with that of the blank sample in the analysis real time in a data analysis unit. At this time, if an inconsistency exceeding a predetermined threshold is detected, the occurrence of the quantitative analysis-inhibitory factors can be detected. Further, based on the inconsistency, the error range of the data can be given to a data set and the like. | 05-05-2011 |
