A LCS/LCSD <br />' was performed to demonstrate precision and accuracy at a hatch 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. 8,600. 800. ug/,l 1 <br /> 02508 TPH Motor Oil C16-C36 n.a. 8,600. 800. 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/MSA samples were not submitted for the project. A LCS/LCSD <br /> was performed to demonstrate precision and accuracy at a batch level. <br /> Due to matrix interference, accurate chlorobenzene surrogate recovery <br />' could not be determined. <br /> Due to interferences from the sample matrix (high sediment content) , the <br />' reporting limit was increased. <br /> 01594 RTEX * Oxygenates by 82605 <br />' 01587 Ethanol 64-17-5 N.Q. 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.
