Analytical chemistry
capillary zone electrophoresis
Chemistry; Analytical chemistry
A type of capillary electrophoresis in which the capillary is filled with a homogenous buffer, and compounds are separated on the basis of their relative charge and size.
rotating platinum electrode
Chemistry; Analytical chemistry
Platinum wire sealed in a soft-glass tubing and rotated by a constant-speed motor; used as the electrode in amperometric titrations. Abbreviated RPE.
gas-solid chromatography
Chemistry; Analytical chemistry
A form of gas chromatography in which the moving phase is a gas and the stationary phase is a surface-active sorbent (charcoal, silica gel, or activated alumina). Abbreviated GSC.
carbon dioxide absorption tube
Chemistry; Analytical chemistry
An absorbent-packed tube used to capture the carbon dioxide formed during the microdetermination of carbon-hydrogen by the Pragl combustion procedure.
salt error
Chemistry; Analytical chemistry
An error introduced in an analytical determination of a saline liquid such as sea water; caused by the effect of the neutral ions in the solution on the color of the pH indicator, and hence upon the ...
gel filtration
Chemistry; Analytical chemistry
A type of column chromatography which separates molecules on the basis of size; higher-molecular-weight substances pass through the column first. Also known as molecular exclusion chromatography; ...
carbon film
Chemistry; Analytical chemistry
Carbon deposited by evaporation onto a specimen to protect and prepare it for electron microscopy.
