Analytical chemistry

retention volume

Chemistry; Analytical chemistry

In gas chromatography, the product of retention time and flow rate.

gas-liquid chromatography

Chemistry; Analytical chemistry

A form of gas chromatography in which the fixed phase (column packing) is a liquid solvent distributed on an inert solid support.

capillary gas chromatography

Chemistry; Analytical chemistry

A highly efficient type of gas chromatography in which the gaseous sample passes through capillary tubes with internal diameters between 0.2 and 0.5 millimeter and lengths up to 100 meters, and ...

reverse bonded-phase chromatography

Chemistry; Analytical chemistry

A technique of bonded-phase chromatography in which the stationary phase is nonpolar and the mobile phase is polar.

gasometric method

Chemistry; Analytical chemistry

An analytical technique for gases; the gas may be measured by instrumental methods or through chemical reactions with specific reagents.

capillary gel electrophoresis

Chemistry; Analytical chemistry

A form of capillary electrophoresis in which a polyacrylamide gel (or other polymeric material) is placed inside the capillary and separation is based on size and charge; often used to separate ...

reversed-phase partition chromatography

Chemistry; Analytical chemistry

Paper chromatography in which the low-polarity phase (such as paraffin, paraffin jelly, or grease) is put onto the support (paper) and the high-polarity phase (such as water, acids, or organic ...
