Detector responds to all compounds and compares the thermal conductivities of two gas flows using a single-filament, single-column design.

• Designed, tested and manufactured by Agilent engineers to work perfectly with our instruments Superior performance

The thermal conductivity detector responds to all compounds, excluding carrier gas. The TCD compares the thermal conductivities of two gas flows – pure carrier gas (also called the reference gas) and carrier gas plus sample components (also called column effluent), using a single-filament, single-column design.
