采用气相色谱-质谱联用技术（GC/MS）分析了阿拉斯加天鹅角（Swan Point）炉床遗址的土壤残留物。还通过燃烧动物骨头来制备实验壁炉，以研究骨火的特性和它们嵌入土壤中的脂质残留物。炉床土壤样品用HCl甲醇溶液衍生化，将结合和未结合的脂肪酸转化为甲酯。测定样品中饱和脂肪酸甲酯的浓度并分析其比例。在古代营火中发现的脂肪酸模式与大型反刍动物和单胃食草动物的燃烧骨头一致。
Gas chromatography - mass spectrometry (GC/MS) is used to analyse soil residues from hearth sites in Swan Point, Alaska. An experimental hearth is also prepared by burning animal bones to study the characteristics of bone fires and the lipid residues that they leave embedded in soil. Hearth soil samples are derivatized with HCI in methanol to convert bound and unbound fatty acids into methyl esters. Concentrations of saturated fatty acid methyl esters in the samples are determined and their ratios analysed. The fatty acid patterns found in ancient campfires are consistent with burning bones of large ruminants as well as monogastric herbivores.
