Abstract

A system for controlling flow of gas in a continuous flow isotope ratio analyser is provided. The system comprises gas inlet and gas outlet lines for providing gas into and from a measuring cell, and at least one switchable flow restriction on the gas inlet line, for selectively controlling gas flow into the isotope ratio analyser. Also provided is a method for determining an isotope ratio using the system according to the invention.
