25.3.1.1 Katharometer A wire, heated electrically and maintained at constant
temperature, is fixed along the axis of a cylindrical hole bored in a metal block,
which is also maintained at a constant temperature. The cylindrical hole is filled
with ...
The Katharometer (Thermal Conductivity or Hot Wire) Detector One further
detector should be mentioned that is commonly used for preparative
chromatography employing packed columns. It is relatively insensitive (a feature
that is necessary ...

Quantitative Chromatographic Analysis
A diagram of the katharometer is shown in figure 24. There are two types of
katharometer, the “in-line” cell where the column eluent actually passes directly
over the filament and the “off-line” cell where the filaments are situated out of the
main ...

Within a katharometer, the element protrudes from a cavity into a channel in a
metal block through which the carrier gas stream flows. There

GAS CHROMATOGRAPHY OF POLYMERS
Katharometer The principle of operating of the katharometer is based on the
change in the electric resistance of the sensor (filament, coil) in relation to the
heat conductivity of the gas leaving the GC column. The heat conductivity of the
gas in ...
