STATE-OF-THE-ART IN THE PRIMARY ISOTOPE MEASUREMENT: WHAT IS AN “ABSOLUTE ISOTOPE AMOUNT RATIO MEASUREMENT“?. Authors: MIHAI VARLAM, STAF VALKIERS. |
||||||
Abstract: Stable isotope measurement techniques are considered as one of the fastest growing analytical areas, especially due to the large range of their applications. However, most frequently, the explored matter is extremely sensitive to small variations in isotope ratios and therefore a high analytical precision of the measurements is required. Fortunately, in most cases, valuable information can be obtained from ''differences'' in isotope amount ratios and most of the related analytical instrumentation (mass spectrometers) has therefore been developed in this direction. | |||||||
