~T do lly!, Penny_ From: Usbeck, Fred [[email protected]] Sent: Wednesday, March 26, 2003 2:23 PM To: [email protected]; Theodorellys, Penny Cc: Radhakrishnan, Krish; Gilsenan, Michael; [email protected]; Playez, Dave; Johnston, Mark Subject: RE: FW: Revised PAH results
Chuck - In response to your question about the change in the reporting limit for the PAH wipe samples: Our normal PQL (practical quantitation limit) is 5 ug for each PAH for this method, however, our MDL (method detection limit) is 1 ug for` each PAH. For this reason we did not need to rerun these samples - we went back to the raw data to verify that there weren't any "hits" above the 1 ug MDL for these samples, and reprinted the report with the revised reporting limit. I will ask the guys in the lab to print a few chromatograms to demonstrate the new 1 ug DL and send them to Andrew at JLC. I'm sure he won't mind sharing these with you. If you have any other questions please get back to me. thanks! Fred
