浩瀚一ci性医疗用品中环氧乙烷残留量测定填充柱Chromosorb 101 HP 60～80Chromosorb 101 HP 60～80

环氧乙烷在室温、常压下为元色气体,具有芳香的醚味,其气体可被某些固体(如橡胶、塑料等)所吸收. 环氧乙烷液体和气体均有较强的杀微生物作用,具有穿透性强、不损坏消毒物品、杀菌光谱、消毒效果可靠的特点.少量环氧乙烷对皮肤黏膜有刺激作用,大量吸入可引起急性中毒,环氧乙烷是一种烷基化剂,有致癌及细胞原浆毒作用.国家标准规定:一次性使用医疗用消毒后的环氧乙烷残留量≤10μg/g.为了准确检测环氧乙烷残留量。

浩瀚色谱（山东）应用技术开发有限公司建立顶空气相色谱测定yi次性医疗用品中环氧乙烷残留量的方法。方法:取适量样品置于顶空瓶中,60℃恒温水浴中平衡60 min,取液上气1.0 ml进行气相色谱分析测定。结果:方法在线性范围98.3μg～491.2μg内呈良好线性关系(r=0.9999),*低检出浓度为0.1μg/g,相对标准偏差为2.3%～5.5%。结论:该方法简单、可靠,适用于一次性医疗用品中环氧乙烷残留的测定。

Ethylene oxide is a primary color gas at room temperature and normal pressure, with an aromatic ether smell, and its gas can be absorbed by some solids (such as rubber, plastic, etc.). Ethylene oxide liquid and gas have strong It has the characteristics of strong penetration, no damage to disinfected items, sterilization spectrum, and reliable disinfection effect. A small amount of ethylene oxide has a stimulating effect on the skin and mucous membranes, and a large amount of inhalation can cause acute poisoning. Ethylene oxide is a kind of Alkylating agent, has carcinogenic and cytoplasmic toxicity. National standard stipulates that the residual amount of ethylene oxide after disinfection for single-use medical use is less than or equal to 10 μg/g. In order to accurately detect the residual amount of ethylene oxide.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a method for the determination of ethylene oxide residues in disposable medical supplies by headspace gas chromatography. Methods: Take an appropriate amount of samples and put them in a headspace bottle, equilibrate in a constant temperature water bath at 60 ℃ for 60 min, and take 1.0 ml of liquid to carry out gas chromatography analysis and determination. Results: The method showed a good linear relationship within the linear range of 98.3μg～491.2μg (r=0.9999), the lowest detection concentration was 0.1μg/g, and the relative standard deviation was 2.3%～5.5%. Conclusion: The method is simple, reliable, and suitable for the determination of ethylene oxide residues in disposable medical products.
