Abstract: | "OBJECTIVE: Direct determination of 35 trace volatile organic compounds in air by portable gas chromatography mass spectrometry( GC-MS). METHODS: The mixed standard gas of different concentration levels was prepared with high purity nitrogen as diluent gas. The samples were injected into the GC-MS by a hand-held probe. Retention time and characteristic ion were used for qualitative analysis, and the internal standard method was usd for quantitation. RESULTS: Under the established experimental conditions, the 35 poisonous substances were separated and determined well. The relative standard deviation was 3. 2%-15. 1%. The average recovery was 75. 1%-121. 4%( n = 6). CONCLUSION: The portable GC-MS method can be used for qualitative and quantitative detection of volatile organic compounds in ambient air" |
