Switching to an alternative carrier gas requires a review of the previously used measurement conditions. This report introduces an example of using hydrogen as a carrier gas for the simultaneous analysis of pesticide residues in food by GC-MS/MS method.

In this report, simazine and thiobencarb, which are pesticides subject to environmental standards related to water pollution, were measured using N₂ carrier gas, and the difference in sensitivity from He, linearity of the calibration curve, and reproducibility during continuous measurement were confirmed.

We have checked the influences of nitrogen carrier gas on JMS-T2000 GC AccuTOF ™ GC-Alpha, and report on MS Tips No. 374-376. This report shows the results of the CI (Chemical Ionization) ion source.

We have checked the influences of nitrogen carrier gas on JMS-T2000 GC AccuTOF™ GC-Alpha, and report on MSTips No. 374-376. This report shows the results of the EI (Electron Ionization) / FI (Field Ionization)combination ion source, which is one of the characteristic multi-ionization ion sources of JMS-T2000 GC AccuTOF™ GC-Alpha.

We have checked the influences of nitrogen carrier gas on JMS-T2000 GC AccuTOF™ GC-Alpha, and report on MS Tips No. 374-376. This report shows the results of the EI (Electron Ionization) / PI (Photo Ionization) combination ion source, which is one of the characteristic multi-ionization ion sources of JMS-T2000 GC AccuTOF™ GC-Alpha.

In this report, we report the statistical analysis of high-mass resolution MALDI-MSI data of various lipids in biological samples.

SpiralTOF™-plus 2.0 with TOF-TOF option can achieve high precursor ion selectivity due to the long flight path of the spiral ion optics used in the 1st TOFMS. In this application note, we report the structural elucidation of a photodegradation product of reserpine as an example of structural analysis of a component close to a possible interference in mass by MS/MS measurement using the SpiralTOF™-plus 2.0 with TOF-TOF option.

Molecular weight confirmation of synthesized oligonucleotides is important for the quality control of pharmaceuticals. In this report, we used the synthesized oligonucleotide (Table 1) as a sample and measured it with a MALDI-TOFMS.

Coffee aroma contains a very large number of components. Therefore, a large number of peaks are observed in TIC chromatogram, and it takes a long time to identify the components of each peak and to analyze differences between samples. In this report, we present the results of differential and integrated analyses performed on coffee aroma components using msFineAnalysis iQ.

We report the results of the integrated qualitative analysis combining library database search and molecular ion confirmation when performing msFineAnalysis iQ.
