结论测定了47种不同离子在常压离子作用下的低场迁移率系数。这些离子是母离子、水合物、部分或全部二聚体或磷酯的分解产物。这些离子的迁移率和质量之间良好的线性相关性意味着，相似离子的迁移率可以从这里提供的数据的回归拟合中确定出来。然而，必须注意的是，通过使用PC/MS仪器，只有两个离子得到了明确的鉴定。虽然迁移率谱可以用这里使用的方式来识别，从而提供有用的数据，但不能保证离子的确切身份。
CONCLUSION The low-field mobility coefficients of 47 different ions formed by atmospheric-pressure ionic reactions of phosphorus esters have been measured. These ions are parent ions, hydrates, partial or full dimers, or decomposition products of the phosphorus esters. The excellent linear correlation between mobility and mass of these ions means that the mobility of similar ions can, with confidence, be determined from the regression fit of the data presented here. One must note, however, that only two of these ions were definitely identified, by use of a PC/MS instrument. While mobility spectra can be identified in the manner used here, and thus give useful data, exact identity of the ions is not assured.
