Water samples are purged directly. Solid sample and oil <br />Date Received at GC/MS Lab: <br />sludge samples are extracted with methanol. An aliquot of the methanol <br />9/12/96 <br />extract is diluted to volume and introduced into the purge -and -trap vessel <br />Date(s) of GC/MS Analysis: <br />for purge -and -trap GCMS analysis. Electron impact, full scan mass spectro- <br />9/12/96 <br />metry is used for the analysis of eluents. <br />GC/MS Analysts: Lucy Mark, <br />GC/MS Method Reference: EPA Method 8260 GC/MS Volatile Organic Analysis <br />Orlando Garbin, Lindl Louie <br />GC/MS VOLATILE ORGANICS ANALYSIS - EPA METHOD 8260 <br />'.�:�tii`fC3 <br />CAS Number <br />Volatile <br />Organic Compound <br />HML# <br />Collector # <br />Matrix <br />960306 <br />PL8196 <br />oil <br />Method <br />Blank <br />Quantitation <br />Limit <br />Units: mg/L mg/L <br />mg/L <br />67-64-1 <br />acetone <br />D <br />D <br />90 <br />71-43-2 <br />benzene <br />ND <br />ND <br />45 <br />108-86-1 <br />bromobenzene <br />ND <br />ND <br />45 <br />74-97-5 <br />bromochloromethane <br />ND <br />ND <br />45 <br />75-27-4 <br />bromodichloromethane <br />ND <br />ND <br />45 <br />75-25-2 <br />bromoform <br />ND <br />ND <br />45 <br />74-83-9 <br />bromomethane <br />ND <br />ND <br />45 <br />104-51-8 <br />n-butylbenzene <br />ND <br />ND <br />45 <br />135-98-8 <br />sec-butylbenzene <br />ND <br />ND <br />45 <br />98-06-6 <br />tert-butylbenzene <br />ND <br />ND <br />45 <br />56-23-5 <br />carbon tetrachloride <br />ND <br />ND <br />45 <br />108-90-7 <br />chlorobenzene <br />ND <br />ND <br />45 <br />124-48-1 <br />chlorodibromomethane <br />ND <br />ND <br />45 <br />75400-3 <br />chloroethane <br />ND <br />ND <br />45 <br />67-66-3 <br />chloroform <br />ND <br />ND <br />45 <br />74-87-3 <br />chloromethane <br />ND <br />ND <br />45 <br />95-94-8 <br />2-chlorotoluene <br />ND <br />ND <br />45 <br />.1— lel — LVL UGMVKu IN^ — L/tit UINuyLcu L = UUPWVWU VOWW 4u411uuu1VI1 /111UL <br />Analyst: <br />Supervisor: <br />
