SIRIX

Introducing SIRIX, our all-new large radius gas source stable isotope ratio mass spectrometer. SIRIX features advanced multicollector technology derived from the Phoenix Thermal Ionization MS. It also includes our unique, patented ATONA® amplifier technology in combination with a high sensitivity, high mass resolution spectrometer design. The result is a powerful, versatile, sensitive, stable isotope mass spectrometer that is intuitive to use, and can also be optimised for the most exacting applications, including the measurement of isotopologues.

Users of SIRIX will also benefit from the capability to significantly increase their throughput compared to existing solution. The exceptionally quiet and stable amplifier system allows for extended measurement times of sample gas, without the need for repetitive calibration with a reference gas, or calibration of different gain resistors.

The image shows mass scans for m/z 44 to 49, clearly showing the potential for SIRIX to be used for the study of CO2 isotopologues, including m/z 48 and 49

The analysis of CO2 isotopologues has become routine, allowing the measurement of Δ47 with sufficient precision to draw meaningful conclusions. Additional information is available from the measurements of Δ48 & Δ49, but existing instrumentation produce inadequate results. The new SIRIX mass spectrometer from Isotopx leverages the dynamic range and exceptional noise performance of the ATONA® detection system to rewrite the rule book.
