家庭用ほこり中のPFASおよび環境汚染物質

The goal of this work was to develop a methodology for the untargeted analysis of a dust standard reference material (NIST 2585) as well as dust samples collected from household and office settings for both legacy and emerging pollutants. The method uses two-dimensional gas chromatography (GCxGC) and high-resolution mass spectrometry (HRTOFMS), is comprehensive, and covers…

Blue bowl of celery with leaves and stalks

セロリの香りの揮発性化合物に関する特性評価

Headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-time-of-flight mass spectrometry (GC-TOFMS) offers a powerful approach for identifying the complex volatile profile of produce. By utilizing mathematical deconvolution and retention index tools, this method successfully resolves coeluting analytes to provide high-confidence characterization of the hundreds of compounds that contribute to the unique aroma of celery.
