<p>Gas-measuring device, particularly for analysis of carbonate samples, comprises a carousel of reaction vessels 16, each to contain separate aliquots of sample and reagent and connected to a common vacuum pump 49, an action station provided with means 27 for disturbing a reaction vessel so as to mix the separated reactants therein, a water trap 36, a cold finger 38 and a mass spectrometer for recovering and measuring carbon dioxide gas generated by the mixed reagents. The device can also be operated in a multiport gas admission mode to measure pre-formed samples of gas. <IMAGE></p> |
