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 17):
The method of  claim 9 , further comprising:\n isolating the variable volume reservoir from the spectrometer and from a supply of the first analyte gas, once the reservoir has taken up first analyte gas through expansion of the reservoir; compressing the volume of the reservoir following the said isolation of the reservoir, until the pressure of the gas within the reservoir reaches a chosen pressure; and connecting the variable volume reservoir to the spectrometer for expulsion of at least a part of the contents of the reservoir thereto.
