摘要
A miniaturized flow-through calorimeter based on silicon integrated thermopile chips has been developed. The flow-through calorimeter is applicable as sensor for the detection of volatile organic compounds as well as for the precise determination of heats of absorption of gases onto thin coatings. Applying fast and reversible reactions as it is the case for the absorption onto polymer coatings the resolution of the heat measurement is approximately 60 nJ. (C) 1999 Elsevier Science B.V.
