Abstract

A sleeve unit for preparing a sample for gas chromatographic analysis comprises an inlet liner having a bore therein, an inlet to the bore, and an outlet from the bore, and an inlet liner insert located with the bore. The inlet liner insert extends across the bore to cause a sample being prepared for gas chromatographic analysis to flow through the inlet liner insert. The inlet liner insert comprises an arrangement of wire, the arrangement creating a restricted pathway for the sample as the sample flows through the bore of the inlet liner to the outlet of the bore, and the wire having a surface having a high thermal conductivity and being substantially chemically inert to the sample.
