Dioxins analysis in fly ash samples by using GC/MS/MS
Dioxins analysis in fly ash samples by using GC/MS/MS

In this application note, we report the measurement result of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in fly ash sample by using a gas chromatograph triple quadrupole mass spectrometer JMS-TQ4000GC (Figure 1). In addition, the obtained measurement results were compared with those of GC/HRMS JMS-800D.

Evaluation of Asphaltene Products by Mass Spectrometry using Catalytic Pyrolysis
Evaluation of Asphaltene Products by Mass Spectrometry using Catalytic Pyrolysis

Catalytic pyrolysis is attracting attention as a means to increase the yield of valuable compounds while reducing coke formation. Also, pyrolysis-gas chromatography-high resolution time-of-flight mass spectrometry (PY/GC/HRTOFMS) system is an effective tool for qualitative analysis of pyrolytic products. In this work, we evaluated the effect of HZSM-5 catalyst on degraded products of asphaltene using PY/GC/HRTOFMS.

Soy Meat Aroma Components Analysis Using Microchamber and Thermal Desorption GC-MS
Soy Meat Aroma Components Analysis Using Microchamber and Thermal Desorption GC-MS

The two-stage thermal desorption system provides high analytical sensitivity. These methods are used in a wide range of fields such as food, fibers, plastics and wood products because of their ability to collect volatile compounds efficiently (MSTips No. 435, 436, 459). In this report, we show the useful analysis results of soy meat aroma compounds using this method.

msFineAnalysis iQ Ver.2 Target Analysis Example Ⅲ Analysis of Beany Odor Compounds in Soy-Based Meat Products by Microchamber and Thermal Desorption GC-MS
msFineAnalysis iQ Ver.2 Target Analysis Example Ⅲ Analysis of Beany Odor Compounds in Soy-Based Meat Products by Microchamber and Thermal Desorption GC-MS

One of the challenges of plant-based meat alternatives is replicating the flavor of animal-based meat, and aroma plays a significant role in that flavor. In particular, reducing the beany odor is a challenge in soy-based meat products, and it is important to identify the trace compounds responsible for this odor in the aroma components of the samples. Thermal desorption (TD)-GC-MS is an analytical method used for analyzing food aroma components. Although the method enables highly sensitive and comprehensive analysis of aroma compounds in samples, searching for specific target compounds among the many detected components can be time-consuming.
