摘要: A newly developed person-portable gas chromatography-mass spectrometry (GC-MS) system was used to analyze several solvent standards, contact cement, paint thinner, and polychlorinated biphenyl samples. Passive solid phase microextraction sampling fast chromatography with a resistively heated low thermal mass GC column were used. Results (combined analysis) obtained in <2 min for solvent, thinner samples, <13 the sample. Mass spectra produced by small toroidal ion trap detector similar those heavily transmission quadrupole spectrometers compounds, simple alkanes, cycloalknes, while benzene ketone compounds analyzed showed evidence ion/molecule reactions trap. For one of cement samples analyzed, no found indicate presence n-hexane, although relevant material safety data ...
