Method for the on-line mass spectrometric determination of oxygen isotope compositions in geological samples |
| abstract |
The invention relates to a method for the on-line mass spectrometric determination of the oxygen isotope compositions (18 O) of geological samples. DOLLAR A The object of the invention is to provide a method for the on-line mass spectrometric determination of oxygen isotope compositions in geological samples, which makes it possible to completely convert the oxygen content of geological samples into the measurement gas carbon monoxide by means of high-temperature pyrolysis. DOLLAR A The object is achieved according to the invention by using halogen compounds as an additive to the mineral samples. Complete pyrolysis of the sample oxygen to CO is thus achieved. DOLLAR A The additive is to be added in excess to the sample in a quantity ratio of 1: 1 to 1: 500 and is weighed into the sample pan (preferably silver or tin) together with the sample in practical measuring operation. DOLLAR A The aggregates should have a grain size in the _m range (a small excess to the sample is necessary), but coarser grain sizes (mm) are also possible. For an optimal reaction, the sample and aggregate should be fine-grained to powdery. |
