Phthalate esters (PAEs) had been used as main plasticizer of products made from polyvinyl chloride (PVC). Since 1950s, PAEs had been problematized from the point of view of environmental pollution because of their migration property from the products to soil and water. PAEs cause not only environmental pollution but also health damage like carcinogenesis and show transferability between plastics. Screening analysis of PAEs is required, however, it is difficult to analyze simultaneously because each PAE has a different volatility depending on the molecular weight. Direct-inlet-probe Ion attachment ionization mass spectrometry (DIP-IA-MS) is one of the promising tools for screening analysis. It can be applied to both liquid and solid samples, however, it is still difficult to measure volatile molecules because they evaporate before measurement start in vacuum sample chamber. In this study, the sealing-cell method is evaluated to expand the application of DIP-IA-MS to volatile sample analysis.
