A LCS/LCSD <br /> was performed to demonstrate precision and accuracy at a batch level, <br /> 05553 TPH - DRO CA LUFT (waters) n.a. 3,800. 190. ug/l 10 <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 /> to that of our #2 fuel oil reference standard (between C10 and C28 normal <br /> hydrocarbons} . <br /> Site-specific MS/MSD samples were not submitted for the project. A LCS ILC SD <br /> was performed to demonstrate precision and accuracy at a batch level. <br /> The observed sample pattern is not typical of diesel/#2 fuel oil. <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. 5,100. 1,000. ug/l 1 <br /> 02508 TPH Motor Oil C16-C36 n.a. 5,100. 1,000. ug/l 1 <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 /> C8 (n-octane) through C40 (n-tetracontane) normal hydrocarbons. <br /> Site-specific MS/MSD samples were not submitted for the project.
