Gas-liquid chromatography in diagnosis of pyogenic arthritis.

Gas-liquid chromatography in diagnosis of pyogenic arthritis.

Pyogenic arthritis must be diagnosed early if joint destruction is to be avoided. Differentiation from other arthropathies is crucial, and immediate aspiration and culture of synovial fluid is essential when infection is suspected. Synovial fluid contains pus cells in all inflammatory arthropathies and, since Gram-staining is of limited reliability, a further rapid screening test for infection ...

Gas liquid chromatography in the rapid diagnosis of meningitis.

Gas liquid chromatography was employed to detect lactic acid in the cerebrospinal fluid of patients suspected of having bacterial meningitis. The technique was found to be both rapid and reliable. Differentiation between aseptic, purulent, and partially treated bacterial meningitis was readily achieved. The effectiveness of therapy in bacterial meningitis was indicated by a rapid fall in the co...

Rapid diagnosis of anaerobic infections by gas-liquid chromatography.

It was postulated that the short chain fatty acids (SCFA) produced by anaerobic bacteria might serve as microbial markers in purulent material. Eighteen pus specimens from various sources were analysed by gas-liquid chromatography (GLC), and the SCFA detected were compared with the microorganisms isolated by conventional methods. It was found that the detection of propionic, isobutyric, butyric...

Wine: Gas and Liquid Chromatography

From the chemical point of view, wines are aqueous alcoholic solutions containing more than 1000 components that can be present at high concentrations (g L ), but also at trace levels (ng L ). Some of these components determine the organoleptic properties of wines, while others are signi"cant for classifying their origin and/or for checking whether some adulteration has taken place. Concentrati...
