Abstract

A process for the chemical determination of an analyte in a specimen using thermally activated atomic absorption spectroscopy where a specimen may be injected directly through sampling port (12) into an atomiser furnace (10) without complicated pretreatment. Constituents of the specimen which may interfere with the process are removed by volatilisation controlled by introduction of reactive gases through gas ports (13, 14) creating reducing, oxidising or neutral environments, and also controlling pH. Volatile substances causing deterioration of the atomiser furnace may also be inhibited or neutralised by introduction of such gases. Suggested gases, by way of example only, are carbon monoxide, ammonia, hydrogen, methane, argon and oxygen.
