Several methods have been proposed to measure trace amounts of PAHs. Gas chromatography- triple quadrupole mass spectrometry (GC-Triple QMS) is commonly used for high sensitivity measurement methods for specific PAHs in complex matrices. Twenty kinds of PAHs shown in Table 1 (left) were measured using JMS-TQ4000GC (JEOL Ltd.) and those the results are reported in this application note.
The characteristics chemical compounds that differ between the two wines were identified by using the differential analysis functionality of msFineAnalysis AI.
In this application, we report on the verification of whether additive analysis in materials can be performed in the same way as conventional QMS using the single QMS mode, and also conducted analysis using msFineAnalysis iQ.
JMS-T2000GC can switch ionization methods without breaking the vacuum by using a EI/FI/FD* combination ion source. In this MSTips, we will introduce crude oil analysis that takes advantage of these ionization methods.
In this MSTips, we report on an example of structure estimation of an unknown compound in lemon juice using msFineAnalysis AI.
In this MSTips, we will report on the reaction observation of palladium (Pd), an exhaust gas purification catalyst, by connecting JMS-Q1600GC to JEM-ARM200F equipped with an in-situ sample holder manufactured by Protochips.
In this work, we reacted discarded polystyrene using a catalyst, which is a known upcycling technique, and qualitatively analyzed the resulting products in a JMS-T2000GC and msFineAnalysis AI.
In this report, we tried to identify the additives by DIP-MS/MS using a sample mixture of a benzotriazole UV absorber and a phosphorus antioxidant.
In this MSTips, we used a time-of-flight mass spectrometer JMS-T2000GC and unknown compounds structure analysis software msFineAnalysis AI to confirm whether the other structural formula could be obtained correctly.
In this MSTips, we will introduce the analysis of terpenes in cedar and cypress wood using thermal desorption (TD)-GC-TOFMS.
