Ethylene oxide Testing and Challenge encountered in relation to Deuterated Standards

Hi Fellow Food Safety Practitioners,

We are setting up a laboratory in the Philippines for Ethylene oxide testing. We are experiencing difficulty in acquiring the following chemicals needed for Method Validation:

1) Ethylene oxide D4

2) 2 Chloroethanol D4

Can someone from this community help us to find a supplier that can provide the abovementioned chemicals?

Thank you very much.

Regards,

Olive

Does Sigma-Aldrich deliver to your location?

Apologies for the delayed reply. Unfortunately, we stopped the laboratory operation/validation of method due to unavailability of the Internal Standards.
