Ethylene Oxide, 2-Chloroethanol (Fumigant) Analysis
Ethylene oxide (EO, ethylene oxide) is a fumigant widely used in the transportation of oil seeds and spices, fumigation during storage, and fumigation of industrial raw materials and medical equipment. Therefore, ethylene oxide and its metabolite 2-chloroethanol (2-CE) are sometimes detected in fumigated foods. However, ethylene oxide and 2-chloroethanol has been pointed out to be toxic to humans. A standard value (MRL) has been established for the sum of ethylene oxide and 2-chloroethanol.
Fujifilm Wako provides mixture standard solution and analytical standard that can be used for the analysis of ethylene oxide and 2-chloroethanol.
