Opto-mechanical design and performance of a compact three-frequency camera for the Millimeter Bolometer Array Camera on the Atacama Cosmology Telescope
2008
The invention relates to an appliance for the oxidation of components in organic samples, in particular for the oxidation of components emerging from a gas chromatograph and for preparation for an analysis of isotope ratios by mass spectrometry, having a chamber with a gas inlet and a gas outlet, having an oxidizer inside the chamber and, in particular, having a heating appliance for the chamber. It is known to use copper oxide as oxidizer. The latter requires continual reoxidation to achieve sufficiently good results of measurement. In addition, at high temperatures, coagulation of the copper occurs. An oxidizer composed of nickel oxide is provided according to the present invention. This is extremely stable to temperature. The chamber receiving the oxidizer is advantageously lined with Al2O3.
