Abstract: In processing chromatographic data, collected by performing a measurement for each of the segments which respectively define time ranges, a system determines whether there is any boundary sandwiched between two temporally continuous segments whose measurement modes are the same and which has the same m/z value designated by an operator to be displayed. If such a boundary exists, the measurement mode common to the two neighboring segments across that boundary is identified, and the system determines whether the parameter values corresponding to that measurement mode are the same. If they are the same, the partial chromatograms corresponding to the two segments show a temporal change in the intensity of the same kind of ion. Accordingly, the two neighboring measurement points across the boundary are connected by interpolation to create a chromatogram with no missing portion.

Abstract translation: 在处理色谱数据时，通过对分别限定时间范围的每个段执行测量来收集，系统确定是否存在夹在测量模式相同并且具有相同m / z值的两个时间连续的段之间的任何边界 由操作员指定要显示。 如果存在这样的边界，则识别跨越该边界的两个相邻段共同的测量模式，并且系统确定与该测量模式相对应的参数值是否相同。 如果它们相同，则对应于两个片段的部分色谱图显示相同种类离子的强度的时间变化。 因此，跨越边界的两个相邻的测量点通过插值连接以创建没有缺失部分的色谱图。
