摘要: In this paper, we describe a new, simple and fast photothermal method for characterizing the quality of natural gas used as automobile fuel. The consists essentially in measuring thermal properties sequence diluted nitrogen with analyser time especially designed purpose. It is shown that proposed capable an accuracy 3%. also detecting traces H2S greater than 7.8 mg m−3 gas. This good accuracy, together its response portability, suggests it routine, local, checking device assurance at retailers' stations.
