Abstract
This invention relates to a gas analysis apparatus (10) for analyzing a substance sample (15) containing molecular hydrogen (16). The gas analysis apparatus includes a separation device (20) having at least one first separation device (21) connected downstream to a measuring device (24). According to the invention, the gas analysis apparatus (10) is equipped with the first separation device (21), which includes a first conduit (31) that is at least partially permeable to molecular hydrogen (16) and at least partially impermeable to the residue (18) of the substance sample (15). The measuring device (24) implements a mass flow (27) and / or volume flow for recording molecular hydrogen (16). The invention also relates to a method (100) for recording the composition of a substance sample (15) by means of such a gas analysis apparatus (10) and the use of non-graphite carbon according to the invention. Furthermore, the invention relates to a method (200) for simulating the operating behavior of such a gas analysis apparatus (10) and a simulation program product (60) suitable thereto.
