GAS INLET SYSTEM FOR ISOTOPE RATIO ANALYSER AND METHOD OF DETERMINING AN ISOTOPE RATIO |
摘要 |
A gas inlet system for introducing gas into an isotope ratio analyser, the gas inlet system including a reference system comprising: a first supply of a reference gas having a first known isotope ratio; a supply of a carrier gas, wherein the supplies of reference gas and carrier gas are each connected by respective reference and carrier gas lines to a first mixing junction where the reference gas and carrier gas combine; a mixing zone connected downstream of the first mixing junction wherein the combined reference gas and carrier gas mix together; an exit line for transporting the mixed gas from the mixing zone to the isotope ratio analyser; and an opening on the exit line, wherein the opening is downstream of the mixing zone. Also provided is a method of determining an isotope ratio. |
