Response of Thermal-Conductivity Cells in Gas Chromatography

Chromatographic measurement of gas-solid interaction potentials

“…This phenomenon has been reported previously and attri buted to a minimum in the thermal conductivity of the mixture (21,22). This would explain the observed results, but no proof was offered for the existence of a minimum.…”

Indirect chromatography using a membrane polarographic detector

“…the response of the TCD depends upon the product of a cell and thermal conductivity factor (17), and the latter depends, not in a simple way, on the difference in conductivity of the carrier and the gas mixture passing through the cell when a component is eluted (17).…”

Sorption-Effect Chromatography

“…Care must be taken if hydrogen is chosen as the carrier gas! Schmauch and Dinerstein (1960) claim that the TCD output is linear up to about 8 mol per cent using a helium carrier gas.…”
