摘要： An analyzer carrying out analysis with a high degree of qualitative accuracy by separating impurities which hinder the analysis while analyzing in real time. An introducing tube is branched with one branched tube directly leading to an ion source for real time analysis. The other branched tube leads to the ion source so as to introduce the sample gas into the ion source at a later time. When a result of the real time analysis shows that a spectrum pattern on a MS spectrum is changed and an increase in the concentration of an impurity is observed, the introducing path for the sample gas is changed so that the sample gas is introduced into the ion source after the impurity is separated at the separation part.

摘要： In a mass spectrometer having ion sources capable of switching between atmospheric pressure chemical ionization and electron impact ionization, a first gas chromatography device capable of separating a sample to meet a condition suitable for atmospheric pressure chemical ionization measurement is connected to upstream of an atmospheric pressure chemical ionization ion source. Part of the sample separated by the first gas chromatography device is introduced to a second gas chromatography device by distributing a flow channel. In the second gas chromatography device, a target substance and background ingredients contained in the sample are further separated and are introduced to an electron impact ionization ion source. By separating the target substance from the background ingredients, an electron impact ionization spectrum of the target substance is obtained without an effect of the background ingredients.

摘要： The invention relates to an LC/MS interface provided with structure that the end of a spray capillary is rarely damaged and the object is to provide the LC/MS interface which a general user can easily operate, which inhibits the extension of a separation band and the deterioration of detection sensitivity and which enables high separation and sensitive analysis. A metallic member having a hole for connecting a separation column and a spray capillary and a resin member for fixing the upstream side of the short spray capillary are used. Further, to enhance operability, spray ionization using gas spraying is used.

摘要： 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.
