Fig. 5: High-temperature gas chromatography/mass spectrometry chromatograms of a total lipid extract, containing beeswax, from potsherd NOK119.
From: Honey-collecting in prehistoric West Africa from 3500 years ago

a. partial total ion current chromatogram and b-f. mass chromatograms displaying ion masses of characteristic fragments from the main compound classes comprising the extract (m/z 85, 73, 103, 257 and 117, respectively), showing one of the molecular structures of each compound class. Green rhombus, n-alkanes (ALK); red circles, n-alkanoic acids (fatty acids, FA); purple stars, n-alkanols (OH); black triangles, fatty acyl monoesters (WE); blue squares, hydroxyl fatty acyl monoesters (HWE); IS, internal standard (n-tetratriacontane). Numbers denote carbon chain length.
