Figure F44. Combined mass chromatograms of the ions m/z 117 + 75 showing the trimethylsilyl ethers and esters of n-alkanols and n-alkanoic acids, respectively, Site C0020. Representative chromatograms for coal, siltstone, and mudstone lithologies. 16:0 = C16 n-alkanoic acid, 18:0 OH = C18 n-alkanol, etc., * = interfering peak derived from drilling operations.
