| titleOfInvention | Method for analyzing particle organic carbon and nitrogen stable isotopes in seawater by EA-IRMS |
| abstract | The invention relates to a method for analyzing granular organic carbon and nitrogen stable isotopes in seawater by utilizing EA-IRMS, which belongs to the field of water quality detection, starts from the whole flow of collection, storage, treatment and detection of a sample, changes the setting and parameters of an instrument, and filters 100ml of distilled water after the collected sample is filtered; the oxygen addition on the elemental analyzer was set to 80s, the combustion tube temperature was set to 700 deg.C, and the filament current on the isotope mass spectrometer was set to 300-400 μ A. The method of the invention reduces the detection cost by 30%, improves the data accuracy and improves the working efficiency. |
