Chromatography is a method for separating the parts of a mixture of either a gas or liquid solution containing different chemicals. For example, pen inks are often made up of different colours. The different bonding properties of each molecule type are exploited. Chromatography is used in both qualitative and quantitative analysis of both organic a...

Chromatography is used in chmistry in a number of applications: 1. Unknown substances left at a crime scene can be identified by separating the molecules that make them up. Matching this unknown chromatogram to chromatograms of known substances can help identify the unknown substance providing a clue to the crime. 2. The ink used in a note left at ...

Paper chromatography is an analytical technique used to separate and analyse mixtures of soluble substances. It is a type of chromatography. This article is all about the type of chromatography known as paper chromatography. We will start by looking at the principles of chromatography before applying them specifically to paper chromatography.
Paper chromatography is an analytical method for separating colored substances, amino acids, cations, and anions by mobile and stationary phase [110,111]. The mobile phase is a developing solution (alcohol solvent) that travels up the stationary phase (chromatography paper strip) by capillary action.
May 24, 2024 · In paper chromatography, the sample mixture is applied to a piece of filter paper, the edge of the paper is immersed in a solvent, and the solvent moves up the paper by capillary action. It is the simplest and commonest form of liquid-liquid chromatography.
In paper chromatography, the paper acts as the stationary phase, a “track” with varying “terrains” determined by its composition and properties. The mobile phase, the “runner,” is a solvent that moves along the paper, carrying the components of the mixture.
