A LCS/LCSD <br /> was performed to demonstrate precision and accuracy at a batch level. <br /> 05553 TPH - DRO CA LUFT (Waters) n.a. 35,000. 2,500. ug/1 100 <br /> According to the California LUFT Protocol, the quantitation for Diesel <br /> Range Organics was performed by peak area comparison of the sample pattern <br /> 0 to that of our #2 fuel oil reference standard (between C10 and C26 normal <br /> hydrocarbons) . <br /> Site-specific MS/MSD samples were not submitted for the project. A LCS/LCSD <br /> was performed to demonstrate precision and accuracy at a batch level. <br /> 01412 Methanol and Ethanol <br /> 01414 Methanol (by Direct Injection) 67-56-1 N.D. 200. ug/l 1 <br /> 02500 TPH Fuels by GC (Waters) <br /> 02501 Total TPH n.a. 4,900. 2,000. ug/1 5 <br /> 02$08 TPH Motor Oil C16-C36 n.a. 4,900. 2,000. ug/1 5 <br /> TPH quantitation is based on peak area comparison of the sample pattern to <br /> that of a hydrocarbon component mix calibration in a range that includes <br />' CB (n-octane) through C40 (n-tetracontane) normal hydrocarbons. <br /> Due to a coeluting peak near its retention time, accurate o-Terphenyl <br /> surrogate recovery could not be determined. <br /> Site-specific MS/MSD samples were not submitted for the project. A LCS/LCSD <br /> was performed to demonstrate precision and accuracy at a batch level. <br /> 01594 BTEX + Oxygenates by 8260B <br /> 01587 Ethanol 64-17-5 N-D. 500. ug/l 10 <br /> 02010 Methyl t-butyl ether 1634-04-4 N.D. 5. ug/l 10 <br /> 02011 di-Isopropyl ether 108-20-3 N-D. 5- ug/l 10 <br /> 02013 Ethyl t-butyl ether 637-92-3 N.D. 5. ug/l 10 <br /> 02014 t-Amyl methyl ether 994-05-8 N.D. 5. ug/1 10 <br /> 2015 t-Butyl alcohol 75-65-0 460. 50. ug/1 10 <br /> 5401 Benzene 71-43-2 8,700. 50. ug/l 100 <br /> 1 0 <br /> 05402 1,2-Dichloroethane 107-06-2 620. 5. ug/l 10 <br /> Lancaster Laboratories,Inc. <br /> M E M B E R 2425 New Holland Pike <br /> Pp Box 12425 <br /> Lancaster,PA 17605-2425 <br /> 717656-2300 Fax-717-656-7.681 ZZ16 Rem.9111700 <br />
