Przykłady 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.

• Enzymes of purine salvage and catabolism in the mouse preimplantation embryo measured by high performance liquid chromatography.

• The synthetic compounds were purified by high performance liquid chromatography.

• Using antigen-matrix affinity chromatography, we purified monospecific antibodies from the rabbit antiserum generated against the crude extracts.

• Concomitant separation of strontium and samarium- neodymium for isotope analyses in silicate samples, based on specific extraction chromatography.

• A gas chromatography syringe was used to obviate the problem of schistosomula lodging in the syringe barrel.

• Residues were dried, derivatized and analysed for fagopyritols or other soluble carbohydrate products by high-resolution gas chromatography, as described above.

• Determination of leucine metabolism and protein turnover in sheep, using gas-liquid chromatography-mass spectrometry.
