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.

Features and Benefits
◊  Patented ATONA® Faraday amplifiers
◊  9 individually moveable Faraday detectors
◊  Simultaneous measurement of m/z 44 to 49
◊  Mass resolving power 5,000
◊  10 ppm precision 48 CO2 / 44 CO2, within 100 minutes
◊  Measure up to 200 nA ion beams

Users of SIRIX will also benefit from the capability to significantly increase their throughput compared to existing solutions. 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
