Abstract
An analyser for measuring carbon in a sample comprises a furnace (3), a reaction vessel (7), a dehumidifier (8), a detector (10), and means (1) for flowing the sample in a carrier gas through the furnace and/or the reactor vessel to produce carbon dioxide, which is passed via the dehumidifier to the detector, characterised in that a carrier gas flow control unit (2) is provided downstream of the furnace. The analyser may also comprise means (20) for providing an additional supply of carrier gas to the carbon dioxide passing through the detector, the additional supply of carrier gas acting to dilute the carbon dioxide.
