Abstract:
A gas inlet system for an isotope ratio spectrometer and a method for coupling analyte gas to an isotope ratio spectrometer are disclosed. A variable volume reservoir is located between a supply of analyte gas and a spectrometer. The reservoir's internal volume is controllably adjusted at a pre-determined rate to generate a defined flow of analyte gas or mixture to or from the reservoir. Analyte gas and carrier gas are taken up by the reservoir on increasing the reservoir's internal volume and then expelled from the reservoir to the spectrometer on decreasing the reservoir's internal volume. An open split can be used together with the reservoir to facilitate splitting away and hence dilution of analyte within the reservoir. A method for cleaning the gas inlet system is provided, which involves flushing the system with carrier gas.

Claim (Index 11):
The method of  claim 10 , further comprising:\n diluting the first analyte gas once the variable volume reservoir has taken it up by: isolating the variable volume reservoir from a supply of the first analyte gas; compressing the reservoir by a known amount so as to expel a proportion of the first analyte gas to the spectrometer and to expel the remaining portion of the first analyte gas to the open split; subsequently expanding again the variable volume reservoir to or by a predetermined amount, at a speed which is smaller than the difference between the uptake of the spectrometer and the carrier gas flow, so as to cause carrier gas to be drawn into the variable volume reservoir and to dilute the first analyte gas therein; wherein the predetermined amount of expansion of the reservoir is selected on the basis of the subsequently desired dilution/concentration of the first analyte gas.
