Also.ask the lab.if. <br /> they have preformed.any maintenance on this instrument since April 2005,.such as cut the column, that might <br /> affect the retention time of the motor.oil CCV.

We do.not <br /> run a daily.Motor Oil standard however, I have attached for your,review a scanned PDF of a <br /> typical 10-30W motor oil chromatogram analyzed in April 2005 on the same GC as this sample. <br /> In addition,.1 have attached the MW-1 TPHd chromatogram and the MW-1 TPHd chromatogram <br /> overlaid with the TPHd standard. I hope this is,sufficient,please give me a call or e-mail with any. <br /> questions. Thanks! <br /> Brandon S.
