Reactor device for chemical and isotopic analyses

摘要

A reactor device (1) is provided, for chemical analysis on a sample (32) designed to be connected to a distributor (31) of samples (32) and to an analytical system (39) suitable for performing said chemical analyses, comprising: a carbon reactor element (2) defining an internal volume (2a), including a carbon crucible (3) suitable for containing said sample (32), a heating element (4) arranged on the outside of said reactor element (2) suitable for bringing the crucible (3) up to temperatures designed to enable the reaction of the carbon with the element being analysed and forming part of the sample (32), so as to obtain an analytical gas, and wherein the reactor element (2) comprises a substrate (20), in contact with the internal volume (2a), and a protective layer (21) made of a ceramic material, suitable for at least partially covering said substrate (20) and for providing a protective barrier for said substrate (20) against atmospheric degradation in high temperature conditions.
