acrolein stability in standards

[chloesabrina]

Can anyone suggest a vendor to use for an acrolein standard? We have to run a second vendor (source) check on our calibration and our second source results are always around 30-60% recovery. This creates a problem for certain states which require a recovery of 75% for all analytes.

Please send suggestions

I wish I could offer a suggestion, but we run into the same problems here and my lab. Sometimes out Acrolein standards do not match up well at all. If anyone has any suggestions I would also love to hear about them!
