Chromatography - Wikipedia
Chromatograph – an instrument that enables a sophisticated separation, e.g. gas chromatographic or liquid chromatographic separation. Chromatography – a physical method of separation that distributes components to separate between two phases, one stationary (stationary phase), the other (the mobile phase) moving in a definite direction.
How does chromatography work? - Explain that Stuff
2022年2月25日 · Gas chromatography is a largely automated type of chemical analysis you can do with a sophisticated piece of laboratory equipment called, not surprisingly, a gas chromatograph machine. First, a tiny sample of the mixture of substances being studied is placed in a syringe and injected into the machine.

Chromatography - Definition, Uses and Types - Biology Dictionary
2018年4月15日 · Chromatography is a method of separating the constituents of a solution, based on one or more of its chemical properties. This could be charge, polarity, or a combination of these traits and pH balance. In essence, the solution is passed through a medium which will hinder the movement of some particles more than others.

2024年4月16日 · Theory. The distribution of a solute between the mobile and stationary phases in chromatography is described by \(\kappa\), the partition coefficient, defined by: \[\kappa = \dfrac{C_s }{C_m} \nonumber \] where \(C_s\) is the concentration of solute in the stationary phase and \(C_m\) is the concentration of the solute in the mobile phase.
