chromatography betydelse and definition

Exempel på chromatography

• 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.
