F • GlossarySiemens (S)Unit measure of conductance; the reciprocal of the electrical resistance of asolution.SuppressorA device used to minimize eluent conductivity and convert sample species to acommon form, thus increasing detection sensitivity.Temperature CoefficientThe percent of change in the conductivity of a solution with a 1 o C change intemperature. Every solution has a characteristic temperature coefficient which isdetermined experimentally.Theoretical Plates (N)See Column Efficiency.Void Volume (V 0 )The volume occupied by the eluent in a packed column. This volume includes thevolume between the injection valve and the column, as well as between thecolumn and the detector cell. Unretained components are eluted in the voidvolume.Doc. 031879-01 3/03 F-5
