环氧乙烷在常温下为无色、可燃的有毒气体,对细菌、芽抱、真菌、病毒等各种微生物在38~54“C下即可杀灭,是一种良好的灭菌剂。由于它的毒性,使用环氧乙烷灭菌法时,除应考察药物本质有无变化外,药物中环氧乙烷的残留量对药物的安全使用关重要。
药物中微量环氧乙烷的测定可用气相色谱法,测定中需要使用低浓度的标准气样。如用注射器直接从高压容器(钢并)取得环氧乙烷,既不易得到纯品气样,又不是低浓度的标样;也有用重量法取样的,由于墓量(容器重量)大,增量(环氧乙烷)小,引进较大的称量误差,都不能达到准确定量的要求〕
滕州市浩瀚色谱仪器技术服务有限公司，介绍一种低浓度环氧乙烷标准气样的配制方法,操作简单,毋需特殊仪器,也可以适用于其它气体标样的制备。

Ethylene oxide is a colorless, flammable toxic gas at normal temperature. It can kill bacteria, buds, fungi, viruses and other microorganisms at 38~54"C. It is a good sterilizing agent. Due to its toxicity, in the case of ethylene oxide sterilization, in addition to the change in the nature of the drug, the residual amount of ethylene oxide in the drug is essential for the safe use of the drug.
Determination of trace amounts of ethylene oxide in pharmaceuticals can be carried out by gas chromatography, which requires the use of low concentrations of standard gas samples. If the ethylene oxide is directly taken from a high-pressure vessel (steel and steel) with a syringe, it is not easy to obtain a pure gas sample, nor is it a low-concentration standard sample; it is also sampled by the gravimetric method, because the tomb volume (container weight) is large, increasing The amount of (ethylene oxide) is small, and the introduction of large weighing error can not meet the requirements of accurate quantification]
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. introduces a method for preparing a low-concentration ethylene oxide standard gas sample. It is easy to operate, requires special equipment, and can be applied to the preparation of other gas standards.
