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

There is no need to present -these chromatograms in a formal manner. <br /> Thank you very much for providing this information. <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 304 E.
