Abstract
Inverse gas-chromatography apparatus for investigating the properties of a solid material, having a carrier fluid, comprising at least two fluid components (typically water and an inert gas); a second flow comprising the carrier fluid components and probe material; a temperature controlled column, for holding the solid material; a switch for selectively passing the flow of carrier fluid and the second fluid flow through the column; a detector for detecting the passage of the probe material through the column. The relative proportions of the fluid components in the flow of carrier fluid and the second fluid flow can be controlled.
