Microvolume Thermal Conductivity Detector (TCD)
Our dual filament TCD is a stand-alone unit consisting of the detector housing
and a controller with electrometer and temperature controls. The detector cell
includes two separate nickel/iron filaments, capable of independent or
referenced (differential) operation. Cell volume and geometry are optimized for
capillary chromatography and enhanced sensitivity at low flow rates.
(Recommended total flow rate: 2-10 mL/min.)
Thermal stability is maintained to ±0.02°C, resulting in a stable, noise-free
signal. A single 0-1 millivolt attenuated output for a strip chart recorder is
provided through the signal cable at the rear of the controller, with 0-1 volt
and 0-10 volt unattenuated signals available through the remote signal cable.
