Abstract:

This article defined the chromatographic band in the chromatography. The relationship between the chromatographic band and the chromatographic peak was discussed in detail, and the analytical band was considered as the basic for the study of chromatographic phenomena. The chromatographic peaks in the chromatography were not limited to the chromatographic peaks in the chromatogram, and a chromatographic peak can be formed corresponding with an analysis bands of the components.

Key words: Component, Intuitive band, Analytical band, Band length, Chromatogram, Sample band
