| Abstract: | Data acquisition and treatment system of Finnigan MAT model 251 mass spectrometer has been remade, and it can determine 15 N abundance of biotic samples with single way and three beams. Precision, accuracy, sample amount and memory effect of this method has been tested. It is confirmed that this method is exact and reliable. |
