Just got my RSA test results. 70ppm n-butane and 250ppm isopropanol. I never got any isopropanol in any of my RSA's and am wondering where it came from.
Theories:
1) cleaned vac chamber with IPA prior to a run...dried before using
2) 50micron screens cleaned in IPA before using
3) lab error
Any other ideas where this came from and what might be any negative effects of 250ppm?
Thanks
