環(huán)氧乙烷在常溫下為無色、可燃的有毒氣體,對(duì)細(xì)菌、芽抱、真菌、病毒等各種微生物在38~54“C下即可殺滅,是一種良好的滅菌劑。由于它的毒性,使用環(huán)氧乙烷滅菌法時(shí),除應(yīng)考察藥物本質(zhì)有無變化外,藥物中環(huán)氧乙烷的殘留量對(duì)藥物的安全使用關(guān)重要。
藥物中微量環(huán)氧乙烷的測(cè)定可用氣相色譜法,測(cè)定中需要使用低濃度的標(biāo)準(zhǔn)氣樣。如用注射器直接從高壓容器(鋼并)取得環(huán)氧乙烷,既不易得到純品氣樣,又不是低濃度的標(biāo)樣;也有用重量法取樣的,由于墓量(容器重量)大,增量(環(huán)氧乙烷)小,引進(jìn)較大的稱量誤差,都不能達(dá)到準(zhǔn)確定量的要求〕
滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，介紹一種低濃度環(huán)氧乙烷標(biāo)準(zhǔn)氣樣的配制方法,操作簡(jiǎn)單,毋需特殊儀器,也可以適用于其它氣體標(biāo)樣的制備。

Determination of ethylene oxide residues in drugs by 407 organic carrier
Determination of Ethylene Oxide Residues in Drugs by 407 Organic Supports

Stationary phase: polymer pellet

Particle size: 80-100 mesh, 60-80 mesh

Specification: 2m*4mm

Model: 407 organic carrier

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.
