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-, <br /> 01729 TPH-GRO - Waters <br /> 01730 TPH-GRO - Waters n.a. 2,100. 50. <br /> The reported concentration of TPH-GRO does not include MTBE or other ug/1 1 <br /> gasoline constituents eluting prior to the C6 (n-hexane) TPH-GRO range <br /> start time. <br /> A site-specific MSD sample was not submitted for the project.
