IN a recent publication 1 from this laboratory, a technique for the study of the chromatographic behaviour of enzymes on paper was described. The ease with which enzymes can be readily identified on ...

THE separation of several non-volatile carboxylic acids by paper chromatography has been described by Lugg and Overell 1,2. These workers found that it was impossible to carry out the separation with ...

As the solvent soaks up the paper, it carries the mixtures with it. Different components of the mixture will move at different rates. This separates the mixture out.

Postnova Analytics have published an informative new white paper that details how multi-detector Asymmetrical Field Flow Fractionation (AF4) and Electrical AF4 (EAF4) techniques are transforming the ...

In literature, the terms “ion exchange chromatography” and “ion chromatography” (IC) are often used interchangeably, thanks to the wide use of IEX, and refer to the separation of polar or ionic ...

The roots of chromatography can be traced back to the early 20th century when Mikhail Tswett introduced the concept of liquid-phase chromatography. Over the years, chromatography techniques have ...
