Gas inlet system for isotope ratio spectrometer |
| abstract |
A gas inlet system 20 for an isotope ratio spectrometer 1 and a method for coupling analyte gas to an isotope ratio spectrometer 1 are disclosed. A variable volume reservoir 5 is located between a supply of analyte gas 9,11 and a spectrometer 1. The reservoir's internal volume is controllably adjusted at a predetermined rate to generate a defined flow of analyte gas or mixture to or from the reservoir 5. Analyte gas and carrier gas are taken up by the reservoir 5 on increasing the reservoir's internal volume and then expelled from the reservoir to the spectrometer 1 on decreasing the reservoir's internal volume. An open split 3,8 can be used together with the reservoir 5 to facilitate splitting away and hence dilution of analyte within the reservoir 5. A method for cleaning the gas inlet system 20 is provided, which involves flushing the system with carrier gas. |
