In this application, we report the analysis of off-flavor components in natural rubber by using HS-GC/MS/MS.

In this report, we performed structural analysis of the end groups of poly(methyl methacrylate) by using MALDI-TOFMS and pyrolysis GC-TOFMS in a complementary manner.

This application note reports the syringe sampling procedure, and measurement results of example compounds that are sensitive to heat and light.

In this report, simazine and thiobencarb, pesticides subject to environmental standards for water pollution, were measured with hydrogen carrier gas. The results show good linearity of the calibration curve and reproducibility at the lower limit of quantification.

In this application note, two types of commercially available PET resins are analyzed by reactive pyrolysis GC-TOFMS and NMR, and the results of analysis to determine whether they are PET or G-PET are reported.

In this report, di(2-ethylhexyl)phthalate, dichloroacetonitrile, and chloral hydrate, which are water quality control target items in water quality testing, were measured by the same column using nitrogen carrier gas. (For He, see MSTips No.325.) As a result, good linearity of the calibration curve and reproducibility at the lower limit of quantification were obtained for all compounds, and are presented in this report.

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.
