THE applications and limitations of one- and two-dimensional paper chromatographic techniques have been well documented 1. There remain, however, problems in the separation of certain compounds which ...

WE have found that, when a mixture containing barbiturate, salicylate and acetophenetidin is subjected to chromatography on Whatman No. DE20 cellulosic ion-exchange paper in dilute ammonia solution, a ...

The wide range of chromatographic techniques share one common aim: to separate a material into its components. A material, your sample, is dissolved in a solvent, called the mobile phase. This mixture ...

Chromatography testing and mass spectrometry are two analytical techniques widely used in scientific research, pharmaceuticals, food safety, environmental analysis, and forensic investigations. These ...

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 ...

As food standards evolve in response to new information on the risks associated with contaminants, the food industry is increasingly adopting advanced analytical methods to ensure compliance.

Chromatography is a process by which compounds within a mixture are separated. Compounds are be separated by properties such as size, and how the compounds interact with the mobile and stationary ...
