Automated 15 N 13 C Analyser (ANCA)

Location: Hebrew University of Jerusalem, Edmond Safra Campus, Givat Ram
The Automated 15N 13C Analyser (ANCA) provides fast and easy measurements of 15N abundance and total N, 13C and total C of variety organic samples with high precision. Soil, plants, organic compounds and other materials can be analysed directly by converting samples on-line into nitrogen and carbon dioxide. These two simple gases are purified by reduction and "trapping chemistry" and separated by gas chromatography. The result is a pure pulse of gas that can be measured by stable isotope ratio mass spectrometry. The precision is 10 ppm 13C and 30 ppm 15N.13C is a tracer of carbon cycling in ecosystems and food chains. 15N is used as tracer in quantitative investigation of the N-cycle. Major applications are determining the fate of applied N-fertiliser and measuring biological fixation of atmospheric N, soil denitrification studies, nitrogen mass balance. Carbon isotope determination in soil carbonates, methane source identification atmospherics carbon dioxide measurements, etc.
