DEVICE FOR CONTINUOUS ISOTOPE RATIO MONITORING FOLLOWING FLUORINE BASED CHEMICAL REACTIONS

摘要

An apparatus for the sensitive detection of the isotope ratio of elements in a sample by a continuous in-line process that converts each element into a new chemical species in an environment comprising fluorine, the apparatus comprising a sample introduction component, a chemical reaction interface (CRI), and a mass spectrometer wherein: (a) the sample introduction component comprises means for continuously introducing the sample into the CRI, and is capable of separating a mixture of analytes into specific molecules; (b) the CRI is capable of converting intact analytes into new compounds of specific elements in an environment comprising fluorine; and (c) the mass spectrometer is capable of making precise isotopic measurements. 3663 כ" ז בשבט התשס" ד - February 19, 2004
