I've had an oil sample analysed by 2 separate labs; one of the labs came back with the analysis stating large amount of contamination with element X (sorry, I won't prejudice any responses with the element name for now). Unfortunately one lab used transmission FTIR and the other used absorbtion...

Edwards replied pretty promptly, it seems there are 24V pumps and 80V pumps and they need 24V or 80V controllers repsectively.

Thanks, I've fired a message off to Edwards, I'll post their response here when I receive it.

I have an Edwards 200H T pump that came without a controller. I managed to get an EXDC160 for a good price, but I'm now concerned whether it is suitable for my pump. The pump is marked as NRA093000 which, as far as I can tell, is a 24V pump. The EXDC is D39641500 which is an 80V controller. What...

Thank you! I'm still learning about high vacuum stuff, so I have a few questions about pumps, etc.

My degree was in electrical and electronic engineering, so I do a lot of electronic projects. I'm also very interested in lasers, and have a decent collection. I'm now venturing into experiments using high vacuums and high voltages.
