| 英文摘要 | A thermal desorption and gas chromatographic method for the analysis of biogenic volatile organic compounds (BVOCs) was established. The air samples were collected on glass adsorbent tubes filled with Tenax-TA, Carboxen 1000 and Carbosieve S III. The sample was thermal desorbed, and then determined by gas chromatography with flame ionization detector. The pre-concentrated samples were dry at 60 degrees C for 2 min, and then thermally desorbed at 250 degrees C for 5 min at 30 mL/min, and secondary desorption was at 275 C for 3 min. A GC-FID was used to detect and. quantify BVOCs. An initial oven temperature of 40 degrees C was maintained for 5 min, and then increased to 120 degrees C at 2 degrees C/min for 1 min, followed by an increase at 20 degrees C/min to 200 degrees C for 10 min. The results showed that eight kinds of BVOCs could be separated by the gas chromatographic condition, which had good precisions and high recoveries. The objective compounds can be calculated very accuracy by a standard curve individually (average r above 0. 99). The precision is lower than 5% and the minimum detectable quantity was 4 x 10(-10) g/L. The desorption efficiency was higher than 96%. The method provides a new way for intensifying the BVOCs. |
