0 a method of finding what separate substances are in a mixture by making it flow, as a liquid or gas, through a material such as paper which different substances pass through at different speeds -- chromatografia
Organic and amino-acid determination were performed by chromatography/mass spectrophotometry.
The particles can be moved by an alternating gas or liquid flow, as in chromatography, or by an alternating electric field, as in electrophoresis.
One example where chromatography may not necessarily be the best analytical method.
The stream of gaseous ammonia that bubbled in the solvent caused the release of the arcing products, which were then analysed by liquid chromatography.
The chemical composition of the headspace volatiles from healthy and fourth instar larvae-infested cowpea seeds were identified, characterized, and compared using gas chromatography-mass spectrometry.
The biochemical evidence typically involves a combination of co-immunoprecipitation and size\mass characterization of the purified material by velocity sedimentation and\or gel-filtration chromatography.
This was added to the column chromatography column after the original extract was applied.
We are in the process of standardizing the technique to measure ethanol levels in blood using gas chromatography, with promising results.
