Ethylene oxide residue tester gas chromatography Test principle: In the sealed bottle, the volatile ethylene oxide molecules escape from the liquid phase into the gas phase on the liquid surface. At a certain concentration, the ethylene oxide molecules reach dynamic equilibrium between the gas and liquid phases. The concentration of ethane in the gas phase is directly proportional to its concentration in the liquid phase. The concentration of ethylene oxide in the gas phase is measured by a gas chromatography instrumentation to determine the residual amount of ethylene oxide in the mask. Ethylene oxide residue tester indicator function: Ethylene oxide is a toxic carcinogen, and the residual amount of ethylene oxide in masks is an important indicator for verifying the hygiene and health of masks. The residual amount of ethylene oxide in the mask cannot exceed 10μg/g.
