测定了一组芳香族化合物的碰撞截面（CCS）值，并评价了这些化合物作为校准和标准化的标准。利用从原油中获得的离子迁移率质谱，用聚DL -丙氨酸进行外部校准，用芳香族化合物进行内部和外部校准。结果表明，该方法具有准确、简便的特点。使用这些芳香标准物得到的精度提高可以解释为它们与原油中分析物的结构更相似。我们预计这些标准的采用将增加IM - MS在石油分析中的效用，并使其更容易直接比较不同研究的结果。
Collisional cross section (CCS) values of a set of aromatic compounds were determined and the compounds were evaluated as standards for calibration and standardization. External calibration with poly‐DL‐alanine and internal and external calibration with the aromatic compounds were performed using the ion mobility mass spectra obtained from crude oils. The results showed that the external calibration method using the set of aromatic compounds is both accurate and easy to implement. The improved accuracy obtained using these aromatic standards can be explained by their greater structural similarity with the analytes in the crude oils. We anticipate that the adoption of these standards will increase the utility of IM‐MS in petroleum analysis and make it easier to directly compare results from different studies.
