Abstract
A sample preparation apparatus for an elemental analysis system comprising a sample combustion and/or reduction and/or pyrolysis arrangement for receiving a sample of material to be analyzed, and producing therefrom a sample gas flow containing atoms, molecules and/or compounds; a gas chromatography (GC) column into which the sample gas flow is directed; a heater for heating at least a part of the GC column; and a controller for controlling the heater. The controller is configured to control the heater so as to increase the temperature of at least the part of the GC column while the sample gas flow in the GC column elutes.
