Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

EtO PPM

Postby guest » Thu Oct 28, 2010 2:30 am

Hello,

I have a problem at work which I could do with some help with.

I have some medical parts which have been sterilized using Ethylene Oxide gas. The parts still have EtO residuals trapped in them. To accelerate the degassing of the product the product is heated for 24 hours.

The parts are placed in a chamber and heated to 43 degrees C.
What I need to work out is EtO gas ppm from 0.267 mg per litre.

The 0.267mg/l figure was calculated by taking the total measured EtO gas remaining in the product and the volume of the chamber.

Any help appreciated.
