However, their low concentrations and high susceptibility to degradation make them difficult to detect using conventional gas chromatography mass spectrometry (GC\/MS). Here we describe the development of a more sensitive liquid chromatography mass spectrometry (LC\/MS) method to detect these compounds.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>A method based on the use of ultra\u2010high\u2010performance liquid chromatography (UHPLC) coupled to an Orbitrap mass analyser was established and validated for the detection of low\u2010concentration ARs in pottery. During the preliminary experiments, UHPLC\u2010Q\/Orbitrap MS (ultra\u2010high\u2010performance liquid chromatography\u2010quadrupole\/Orbitrap mass spectrometry) was demonstrated to be more sensitive, and a wide range of AR homologues in cereal extracts were detected, unlike UHPLC\u2010QTOFMS (ultra\u2010high\u2010performance liquid chromatography\u2010quadrupole time\u2010of\u2010flight mass spectrometry) and GC\/MS. The developed method was utilised to profile AR homologue distribution in modern cereal samples and reanalyse AR\u2010containing pots from the archaeological site of Must Farm.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A highly sensitive LC\/MS method with a limit of detection (LOD) of 0.02\u2009\u03bcg\/g and a limit of quantification (LOQ) of 0.06\u2009\u03bcg\/g was used to profile ARs in five modern cereal grains. The obtained LOD is 250 times lower than that obtained using the conventional GC\/MS approach. AR 21:0 was the most abundant homologue in all four\n                      <jats:italic>Triticum<\/jats:italic>\n                      spp.\u2014einkorn, emmer, Khorasan wheat and common wheat. Meanwhile, AR 25:0 was the predominant homologue in barley, potentially enabling differentiation between wheat and barley.
