detection of ethylene oxide

Health risk assessment of ethylene oxide residues in ...

German regional authorities have detected residues of the substance ethylene oxide in prod-ucts containing sesame seeds from India. The affected products comprised various catego-ries such as bars, snacks or salad toppings and were taken off the market. At the same time, the public was informed by means of the EU’s rapid alert system. In the EU, ethylene oxide is prohibited from any use in ...

Production of Ethylene Oxide

Production of Ethylene Oxide Ethylene oxide, C2H4O, is a color-less, flammable gas or liquid. Because of its molecular structure ethylene oxide is one of the most versatile chemical intermediates. Industrial production started in 1925 using the chlorohydrin pro-cess and was improved in 1931 by introducing the much more economic direct catalytic oxidation method. Currently, almost all ethyl-ene ...

Methods for the determination of ethylene oxide

ethylene oxide per 1 g activated carbon can be detected. This corresponds to ethylene oxide concentrations of mL/m3 (ppm) or mg/m3 for an air sample volume of 10 L. A Selectivity The selectivity of the method depends on the type of gas chromatography column. In practice the capillary column described has proved suitable. If interfering substances are

ETHYLENE OXIDE - World Health Organization

Ethylene oxide in air can be determined by packed column gas chromatography (GC) with an electron capture detector (ECD) (NIOSH Method 1614), with an estimated limit of detection of 1 µg ethylene oxide per sample (National Institute for Occupational Safety and Health, 1987). A similar method is reported by the Occupational Safety and Health

Detection of interstellar ethylene oxide (c-C2H4O)

We report the identification of 10 transitions that support the detection of the small cyclic molecule ethylene oxide (c-C2H4O) in Sgr B2N. Although one of these transitions is severely blended, so that an accurate intensity and line width could not be determined, and two other lines are only marginally detected, we have done Gaussian fits to the remaining seven lines and have performed a ...
