In this report, we analyzed the oligomer region of the same samples using a high-resolution MALDI-TOFMS JMS-S3000 "SpiralTOF™-plus 2.0" in combination with Kendrick Mass Defect (KMD) analysis.

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 MSTips No. 333, we reported the measurement results of anionic surfactants less than m/z 1000. In this application note, we report the measurement of polyethylene glycol (average molecular weight 5000) having phosphate groups as an end group.

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.

Here, we will report on the binary copolymer search function newly added to msRepeatFinder V6 and the resulting compositional analysis of EO-PO copolymers using the degree of polymerization plot.

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.
