Analytical chemistry

Retention index

Chemistry; Analytical chemistry

In gas chromatography, the relationship of retention volume with arbitrarily assigned numbers to the compound being analyzed; used to indicate the volume retention behaviour during analysis.

Gas chromatograph

Chemistry; Analytical chemistry

The instrument used in gas chromatography to detect volatile compounds present; also used to determine certain physical properties such as distribution or partition coefficients and adsorption ...

Capillary electrochromatography

Chemistry; Analytical chemistry

A separation technique in which analytes are transported through a small-diameter packed column by electroosmosis (electrically induced flow of the mobile phase) by applying a high potential (5–30 ...

Retention time

Chemistry; Analytical chemistry

In gas chromatography, the time at which the center, or maximum, of a symmetrical peak occurs on a gas chromatogram.

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.

Gas chromatography

Chemistry; Analytical chemistry

A separation technique involving passage of a gaseous moving phase through a column containing a fixed adsorbent phase; it is used principally as a quantitative analytical technique for volatile ...
