    Abstract:
    Objective: To develop a new solid sorbent tube for capturing glycidyl methacrylate (GMA) in workplace air, and establish a complete set of method. Methods: GMA in workplace air was captured by the new solid sorbent tube filled with carbon aerogel adsorbent, desorbed with solution of 50% (V/V) dimethylformamide-carbon disulfide, separated through capillary chromatographic column, and then analyzed by gas chromatography-flame ionization detector. Results: The linear range of GMA was 0.38-604.80 mg/L, and the related coefficient was 0.999 82. The within-run and the between-run precision were 1.11%-2.80% and 2.53%-4.84% respectively. The average desorption efficiency was 93.20%-94.97%. The minimum quantification concentration and The minimum quantification concentration were 0.02 and 0.07 mg/m(3) respectively (3.00 L sample) . Samples could be stored for at least 8 days at room temperature. Conclusion: The newly developed solid sorbent tube and its complete set of gas chromatography method is simple, and has high sensitivity and precision, so it can be used for sampling and quantitative detection of GMA in workplace air. 目的： 研制一种新型的固体吸附剂管用于采集工作场所空气中甲基丙烯酸缩水甘油酯（GMA），并建立配套的测定方法。 方法： 采用内装全碳气凝胶作为吸附剂的固体吸附剂管采集工作场所空气中GMA，用体积分数为50%的二甲基甲酰胺-二硫化碳溶液解吸，经毛细管色谱柱分离，氢火焰离子化检测器测定。 结果： GMA质量浓度为0.38~604.80 mg/L线性关系良好，相关系数为0.999 82；方法批内精密度相对标准偏差（RSD）为1.11%~2.80%，批间精密度RSD为2.53%~4.84%；平均解吸效率为93.20%~94.97%；最低检出质量浓度为0.02 mg/m(3)，最低定量质量浓度为0.07 mg/m(3)（以采集3.00 L空气计）；样品在室温下至少可保存8 d。 结论： 该方法操作简单，灵敏度高，精密度好，适用于工作场所空气中GMA的采样和检测。.
