Abstract
A process and to an apparatus for isotope ratio analysis having the steps of: performing an LC process and thus providing a first eluate which comprises at least one first liquid carrier fluid and one or more analytes, collecting a portion of interest from the eluate, processing the eluate portion of interest by combining with a second liquid carrier fluid and removing the first carrier fluid to form a processed eluate portion, processing the processed eluate portion to form one or more gaseous conversion products of the analytes, and supplying the gaseous conversion products with gaseous carrier fluid to an isotope analyzer and determining the isotope ratios.
Claims29
A process for isotope ratio analysis, comprising the steps of:
- a) performing an LC process and thus providing a first eluate which comprises at least one first liquid carrier fluid and one or more analytes,
- b) collecting a portion of interest from the eluate,
- c) processing the eluate portion of interest by combining with a second liquid carrier fluid and removing the first carrier fluid to form a processed eluate portion,
- d) processing the processed eluate portion to form at least one gaseous conversion products of the analytes, and
- e) supplying the gaseous conversion products with gaseous carrier fluid to an isotope analyzer and determining the isotope ratios.
An apparatus for isotope ratio analysis, comprising:
- a) a liquid chromatograph, which releases an eluate which comprises at least one analytes,
- b) LC a device arranged downstream of the liquid chromatograph, for taking up at least a portion of the eluate and for exchanging or replacing a liquid carrier fluid present in the eluate portion with a second liquid carrier fluid and for forming an eluate portion processed in this way,
- c) a device for forming at least one gaseous conversion products of the analytes from the processed eluate portion, and
- d) an isotope analyzer to which the gaseous conversion products can be supplied.
A process for isotope ratio analysis, comprising the steps of:
- a) collecting a portion of interest of an eluate from an LC process, said eluate portion comprising at least one liquid carrier fluid and at least one analytes,
- b) processing the eluate portion of interest by combining with a second liquid carrier fluid and removing the first carrier fluid to form a processed eluate portion,
- c) processing the processed eluate portion to form at least one gaseous conversion products of the at least one analytes,
- d) supplying the at least one gaseous conversion products (U) with gaseous carrier fluid to an isotope analyzer and determining the isotope ratios.
An apparatus for isotope ratio analysis, comprising:
- a) a device for taking up a portion of the eluate from a liquid chromatograph, said eluate comprising at least one analytes, and for exchanging or replacing a liquid carrier fluid present in the eluate portion with a second liquid carrier fluid and for forming an eluate portion processed in this way,
- b) a device for forming at least one gaseous conversion products of the at least one analytes from the processed eluate portion, and
- c) an isotope analyzer to which the at least one gaseous conversion products (U) can be supplied.
