To establish a method for determination 1-bromopropane (1-BP) in workplace air by gas chromatography-flame ionization detector (GC-FID).
1-bromopropane in workplace air was collected with activated charcoal tube, then desorbed by carbon disulfide and determined by GC-FID. 1-bromopropane was quantitatively measured using retention time and peak area.
Linear regression formula was Y = 3353.4x-10064 in a range of 2.50 ∼ 500.00 µg/ml with regression coefficient R = 0.9998. Detection limit was 0.25 µg/ml and the lowest detection concentration of 1-brmopropane in air was 0.14 mg/m(3) (at air volume 1.8L). The mean recoveries of 1-BP were between 96.8% and 102.6%, and relative standard deviation of inter and intra-assay was less than 10%. The average desorption efficiencies were between 93.2% and 104.4%. The samples in activated charcoal tube could be stably stored for 5 days at room temperature.
The method could be feasible to determine 1-bromopropane in workplace air.
建立气相色谱 - 火焰离子化检测器（GC - FID）测定工作场所空气中1 - 溴丙烷（1 - BP）的方法。
用活性炭管采集工作场所空气中的1 - 溴丙烷，然后用二硫化碳解吸，采用GC - FID测定。利用保留时间和峰面积对1 - 溴丙烷进行定量测定。
在2.50～500.00μg/ml范围内，线性回归方程为Y = 3353.4x - 10064，回归系数R = 0.9998。检出限为0.25μg/ml，空气中1 - 溴丙烷的最低检出浓度为0.14mg/m³（采气1.8L时）。1 - BP的平均回收率在96.8%～102.6%之间，批内和批间相对标准偏差均小于10%。平均解吸效率在93.2%～104.4%之间。活性炭管中的样品在室温下可稳定保存5天。
该方法可用于测定工作场所空气中的1 - 溴丙烷。
