ABSTRACT:
Gas is transferred for analysis from a sampling probe (15), which may be in the waste gas duct (14) of a steelmaking vessel (10), to remote analysers (31, 32, 33). A high transfer speed is achieved by passing the gas at a relatively high gas transfer rate from the sampling probe (15) along a relatively long first sampling duct (16), while a relatively short duct (25) takes gas at a relatively low gas transfer rate from the long duct to the analysers.
