Apparatus and method for combustion analysis a sample by determining incomplete combustion in a combustion analyser comprising a combustion chamber (60). A sample is supplied to the combustion chamber and combusted to produce combustion products. A target gas characteristic of incomplete combustion of the sample is detected in the combustion products by a target gas sensor (72). The target gas may be carbon monoxide, methane, methanal and/or methanol, among others. Whether incomplete combustion of the sample has occurred may be determined. A signal indicative of incomplete combustion is outputted from the target gas sensor and the combustion products can be directed to waste using a valve (66) disposed upstream of the target gas sensor (72). Faulty analysis measurements and/or contamination of downstream components, including the target gas sensor, which would otherwise result from incomplete combustion - in particular, from soot formation - can thereby be avoided.
