Analysis of organic residues of archaeological origin by high-temperature gas chromatography and gas chromatography-mass spectrometry

Evershed, Richard P., Heron, Carl, Goad, L. John·1990·The Analyst

Abstract

Organic residues are extracted from materials of archaeological interest by solvent extraction and subjected directly to high-temperature gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The use of high-temperature GC allows intact acyl lipids, e.g., triacylglycerols, diacylglycerols, monoacylglycerols and wax esters, to be analysed without prior degradation (e.g., saponification) to release constituent fatty acids and alcohols. Trimethylsilylation is employed to block protic sites in free fatty acids and hydroxylated components. The data obtained from temperature programmed GC and GC-MS analyses, employing immobilised apolar (dimethyl polysiloxane type) stationary phases, provide essential compositional information that would be lost if the more conventional degradative approach to acyl lipid analysis was adopted.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
