    Looking for help with interpretation of FTIR transmission plot

    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 absorption...

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