The MST website has published analysis cases. ◆Title Gas Emission Analysis and Polymer Material Identification Using Pyrolysis GC/MS ~About the Principles and Applications of Pyrolysis GC/MS~ ◆Measurement Method / Processing Method GC/MS ◆Product Fields Lighting, Display, Cosmetics, Daily Necessities ◆Analysis Objectives Chemical Bond State Evaluation, Safety Testing, Thermal Property Evaluation ◆Overview Pyrolysis GC/MS is a gas chromatograph mass spectrometer equipped with a pyrolysis device in the sample introduction section. For polymer materials that previously required complex pretreatment, the sample can be heated using the pyrolysis device, allowing the gases generated to be introduced into the GC for analysis without pretreatment. Additionally, by varying the temperature conditions of the pyrolysis device and the sampling conditions (double-shot method), it is possible to obtain two different types of information separately, such as additives and polymer materials, from the same sample, making the analysis of unknown polymer materials easier. ★★For detailed data, please see the linked page★★

    It is an analytical method for qualitative and quantitative analysis of organic compounds.

    ■Sample Introduction Gases or easily vaporized liquids can be directly introduced into the GC. For solids, depending on the analysis purpose, they are dissolved or vaporized using methods such as solvent extraction, pyrolysis, or headspace methods before being introduced into the GC. ■Component Separation The vaporized sample introduced into the sample introduction section is carried by the carrier gas and passes through the column. Due to the varying strengths of interactions with the stationary phase in the column, each component in the sample moves at different speeds, resulting in separation. ■Ionization (EI Method) The molecules of each component separated by the GC are sequentially introduced into the mass spectrometer, where they are ionized by colliding with thermal electrons emitted from a filament. Some of the generated ions (molecular ions) further fragment to produce fragment ions. ■Mass Separation (Quadrupole Type) The generated ions are introduced into a quadrupole mass spectrometer consisting of four rods. By adjusting the voltage applied to the rods, only ions of a specific mass reach the detector, resulting in a mass spectrum containing molecular mass information.
