Introduction

In recent years, measures to reduce the use of organic compounds in automotive interiors have progressed, the ISO 12219-11 standard is being developed for the analysis of volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) that are emitted from automotive interior materials. The ISO 12219-11 analytical procedure involves filling a thermal desorption (TD) glass tube with a sample of materials, heating the tube using TD, and loading the VOCs (up to C25) and SVOCs (C14 to C32) that were emitted from the sample into a GC-MS system for analysis. Although this standardized procedure enables simple and quick analysis of VOC and SVOC emissions from these materials, contamination of the MS system caused by the simultaneous loading of compounds with high boiling points is a problem. The GCMS-QP2050 is equipped with a new contamination-resistant ion optical system that effectively minimizes contamination of the MS. Featuring a new interface that enables good peak shape and sensitivity even for compounds that are typically prone to adsorption, it is optimally suited to analyzing SVOCs, including those with high boiling points. TD-30R and GCMS-QP2020 NX will be listed as examples for suitable test equipment on ISO 12219-11. This Application News describes analyzing VOC and SVOC emissions from the materials of vehicle interiors in compliance with ISO 12219-11 using the GCMS-QP2050 together with the Nexis GC-2030 and the TD-30R thermal desorption system.
