A rapid method for the analysis of methyl dihydrojasmonate and galaxolide in indoor and outdoor air particulate matter.

A method for the analysis of methyl dihydrojasmonate (MHDJ) in air particulate matter (PM1 and PM2.5) is described for the first time. This fragrance is determined together galaxolide (HHCB).

Broad spectrum analysis of polar and apolar organic compounds in submicron atmospheric particles.

A method for the quantitative analysis of organic compounds on submicron particulate matter (PM1) collected on quartz filters was developed. The compounds analyzed encompassed C22-C35 alkanes, polycyclic aromatic hydrocarbons (PAHs), quinones, levoglucosan, cis-pinonic acid and short chain dicarboxylic acids such as malonic, succinic, glutaric, adipic, suberic, azelaic, malic and phthalic acids. The method included extraction with a pressure liquid extraction system, sample filtration though glass fibre filter, fractionation by high performance liquid chromatography and subsequent analysis by gas chromatography coupled to mass spectrometry.
