| Definition | The ANCA-GSL module allows samples such as soil, viscous liquids, plant material and organic compounds, to be analysed directly by using Dumas combustion for 15N, 13C & 34S or pyrolysis for 18O and D. It also allows isotope analysis of abundant gases from septum sealed containers. During combustion mode, a capsule containing the sample falls into the combustion tube and is converted in the presence of oxygen to CO2, N2, NOx and H2O. An elemental copper stage reduces NOx, a MgClO4 trap removes water vapour, a switchable Carbosorb trap can be used to remove CO2 (for 15N only analyses) and a GC column separates CO2 from N2 (allowing dual isotope analysis). Modified packings, a Nafion dryer and different GC column allow 34S analysis. The sample preparation unit consists of a 66 place autosampler for unattended operation (larger options are available), 2 furnaces able to operate to 1100 deg C, an on-board microprocessor. The analyser is capable of dual isotope analysis of 15N and 13C. For CO (18O), H2 (2H), N2 (15N), CO2 (13C), CO2 (18O) and SO2 (34S) with precisions between 0.1 and 3 dependent on the element. | |
