Analytical chemistry

electrical calorimeter

Chemistry; Analytical chemistry

Device to measure heat evolved (from fusion or vaporization, for example); measured quantities of heat are added electrically to the sample, and the temperature rise is noted.

analysis

Chemistry; Analytical chemistry

The determination of the composition of a substance.

polarogram

Chemistry; Analytical chemistry

Plotted output (current versus electrode voltage) for polarographic analysis of an electrolyte.

electrical equivalent

Chemistry; Analytical chemistry

In conductometric analyses of electrolyte solutions, an outside, calibrated current source as compared to (equivalent to) the current passing through the sample under analysis; for example, a ...

analyte

Chemistry; Analytical chemistry

1. The sample being analyzed. 2. The specific component that is being measured in a chemical analysis.

polarographic analysis

Chemistry; Analytical chemistry

An electroanalytical technique in which the current through an electrolysis cell is measured as a function of the applied potential; the apparatus consists of a potentiometer for adjusting the ...

electrobalance

Chemistry; Analytical chemistry

Analytical microbalance utilizing electromagnetic weighing; the sample weight is balanced by the torque produced by current in a coil in a magnetic field, with torque proportional to the current.
