| 中文摘要: |
| 采用全采样系统-全二维气相色谱/飞行时间质谱联用技术监测环境空气中的VOCs，优化了调制周期、升温程序、进样体积等分析条件。39种目标化合物在0 μg/m3～10.0 μg/m3范围内线性良好，检出限范围为0.03 μg/m3～0.09 μg/m3，标准气体平行测定的RSD为1.1%～5.3%。应用于化工园区环境空气样品测定，与热脱附-气相色谱/质谱法相比，目标物的分离效果更佳。 |

| A whole sampling system-comprehensive two-dimensional gas chromatography/time of flight mass spectrometry method was established to monitor the VOCs in ambient air. The modulation cycle, temperature program, sampling volume were optimized. 39 kinds of target compounds showed good linearity in the range of 0 μg/m3～10.0 μg/m3. Detection limits ranged from 0.03 μg/m3 to 0.09 μg/m3. Standard gas parallel determination of RSD 1.1%～5.3%. The current method was applied to determination the ambient air sample in chemical industrial park. Compared with the thermal desorption method, target compounds showed better separation effect by current method. |
