Detection of ethylene oxide residues in medical masks
Detection of ethylene oxide residues in medical masks Details:

Name: Packed column

Stationary phase:/organic polymer pellets

Particle size: 80-100 mesh, 60-80 mesh

Specification: 2m*4mm, 2m*3mm

Model: GDX-407

Application: Determination of Ethylene Oxide Residues in Masks Gas Chromatography



Detection of residual ethylene oxide:

  GB/T 19083-2010 Medical protective masks: masks sterilized by ethylene oxide, the residual amount should not exceed 10μg/g.

  GB/T 32610-2016 daily protective mask: masks treated with ethylene oxide shall be implemented in accordance with the provisions of Chapter 9 of GB/T 14233.1-2008, and the residual amount of ethylene oxide should not exceed 10μg/g.

  YY/T 0469 Medical surgical masks: masks sterilized by ethylene oxide, the residual amount should not exceed 10μg/g.

  YY/T 0969 Disposable medical masks: If the mask is sterilized or disinfected with ethylene oxide, its residual ethylene oxide should not exceed 10μg/g.


The new crown pneumonia has a large demand for masks, and the hygiene and safety of masks cannot be ignored. Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. uses GDX-407 packed columns to determine the residues of ethylene oxide in masks. The column efficiency is high and the separation is good. Interference, symmetrical peak shape.
