説明
<p> A proton transfer reaction-quadrupole interface-time of flight mass spectrometer was combined with a hand-made thermal desorption instrument for real-time analysis of organic aerosol particles. Size-selected single component organic particles were generated using a nebulizer combined with a differential mobility analyzer. We tested Teflon and copper tubing for the thermal desorption instrument. Higher signal intensities were observed when we used Teflon tubing, suggesting that wall deposition loss of vaporized semivolatile organic compounds is suppressed when Teflon tubing is used. Protonated molecules, [M+H]+, had the highest intensity in the mass spectrum of carbonyl particles (i.e., terephthaldialdehyde particles), whereas ions formed by the dehydration from protonated molecules, [M+H-H2O]+, had the highest intensities in the mass spectra of carboxylic acid particles (i.e., adipic acid, phthalic acid and cis-pinonic acid particles) and alcohol particles (i.e., meso-erythritol particles). The mass spectra obtained for organic aerosol markers will be useful to interpret mass spectra measured for organic aerosol particles by thermal desorption-proton transfer reaction-mass spectrometry. </p>
