Ethylene Oxide (C2H4O)

Ethylene oxide (EtO) is used in the large-scale production of chemicals, as a fumigant in certain agricultural products, as a sterilizing agent for medical devices, and can be found in the atmosphere as a pollutant emitted from natural gas, cigarette smoke and diesel exhaust. Despite its relatively common usage, the Occupational Safety and Health Administration (OSHA), the National Institute for Occupational Safety and Health (NIOSH), the International Agency for Research on Cancer (IARC), the American Conference for Governmental Industrial Hygienists (ACGIH), the German MAK commission and others, have classified it as a toxic substance with proven mutagenic properties, solidifying its position as a carcinogen. While the mutagenic properties of Ethylene Oxide have been known since the 1940s, the regulatory landscape around emissions and exposure limits has evolved with the publication of the most recent National Air Toxics Assessment (NATA) in the US.

Using innovative next-generation laser technology, Picarro has developed a family of CRDS-based analyzers capable of measuring ppt levels of EtO in real time (< 2 seconds) and without the need for chromatographic separation or pre-concentration.

G2910 气体浓度分析仪

  在 Picarro 环氧乙烷(EtO)气体浓度分析仪系列中,G2910 烟气及室内空气质量分析仪被配置为在排放源处测量 EtO。G2910 支持在宽浓度范围内测量复杂的气体混合物,同时不影响精度和稳定性。在需要准确实时量化 EtO 排放的应用中,Picarro 比傅里叶变换红外光谱(FTIR)和气相色谱(GC)等传统技术更胜一筹。对烟囱、减排系统、灭菌室、曝气仓库及建筑物通风设施的 EtO 量化变得非常简单。
