Anyone experienced in determining ethylene oxide residuals in medical devices after sterilization - ISO 10993-7?
We need to analyze ethylene oxide and 2-chloroethanol (ethylene chlorohydrin).
Temperature of boiling point at atmospheric pressure for 2-chloroethanol is 128,6 °C
Our solvent is water.
Our carrier gas is He.
We have problems separating the peaks (water + 2-chloroethanol).
Which temperature we should select for injection?
We tried a lot of variations of the split, injection temperature, oven temperature.
Thanks,
