Definitions for "chromatogram"
the paper strip, column, gel, or TLC plate on which subsances have been separated by a process of chromatography{2}.
the record of the results of a process of chromatography{2}, produced by an instrument which measures some property related to the concentration of substances over the course of a chromatographic process. The record may be printed, for example, on a piece of paper, showing the concentration of some substance as a function of time or volume; or it may be retained in a computer and displayed on a video display terminal.
A plot of detector response against peak volume of solution (eluate) emerging from the system for each of the constituents which have been separated.
A separation of substrates, usually proteins, by some method that keeps like substrates together but separates each from other different substrates. For example, a Liquid Column Chromatogram is a long cylindrical glass tube mounted vertically and filled with extremely small glass beads. Proteins dissolved in water is added in at the top and then water is drawn off at the bottom into a different test tube every 10 minutes or so. The smaller proteins can get through the glass beads quicker than the larger proteins, so the smaller proteins will be in a test tube drawn at an earlier time from the bottom of the column.
