How to Read a Chromatogram? - Lab-Training.com
2024年7月17日 · Chromatogram definition can be understood simply by studying what a chromatogram depicts. The chromatogram is a two-dimensional plot with the ordinate axis giving concentration in terms of the detector response, and the abscissa represents the time.
Chromatography - Wikipedia
In chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the stationary phase is fixed.

2023年8月29日 · The time to elute an analyte is a function of how long the analyte is retained on the column, therefore the output of IC is a graph of conductivity as a function of time, called a chromatogram. Based on the previous discussion of elution, you may expect a chromatogram to look something like:
Chromatography | Definition, Types, & Facts | Britannica
2024年9月26日 · chromatography, technique for separating the components, or solutes, of a mixture on the basis of the relative amounts of each solute distributed between a moving fluid stream, called the mobile phase, and a contiguous stationary phase. The mobile phase may be either a liquid or a gas, while the stationary phase is either a solid or a liquid.
