研究了车间空气中环氧丙烷的大玻璃注射器采样,聚乙二醇-6000通用柱分离的气相色谱法。该法精密度高,变异系数低于2.7％。在0.02～0.5μg/ml范围内呈线性关系。检测限为2.0×10~3μg(直接进样1ml)。
A large glass syringe sampling of propylene oxide in the workshop air and a GC separation of polyethylene glycol 6000 column were studied. The method of high precision, coefficient of variation of less than 2.7%. In the range of 0.02 ~ 0.5μg / ml linear relationship. The detection limit was 2.0 × 10 ~ 3μg (direct injection 1ml).
