  • Collision cells are back in fashion!

    Collision cells are back in fashion!

    After a period of time working away from inorganic isotope ratio MS, I returned to the community to see that there has been an interesting resurgence in the application of collision cell technologies. This blog won’t look at the new solutions, but I thought it worth taking some time to look at where it all…

  • Thermal ionization mass spectrometry for kids!

    Thermal ionization mass spectrometry for kids!

    My kids are of an age (12 and 13) where science is both simultaneously daunting and eye opening on a daily basis. The older one is just starting to learn about atoms and elements, giving me ample opportunity to regale her with information about the instruments I work with, whilst giving her ample opportunity to…


  • The story behind ATONA – embracing the capacitor

    The story behind ATONA – embracing the capacitor

    I often get asked about the ATONA Faraday amplification system that we use at Isotopx. The questions are usually along the lines of “how did you come up with the idea?”, or “was it hard to develop?”, typically ending with “what’s next?”. In this blog I’ll address those questions – with the obvious limitation that…


  • Nuclear decommissioning and isotope ratio mass spectrometry

    Nuclear decommissioning and isotope ratio mass spectrometry

    I recently attended the 14th International Symposium on Nuclear and Environmental Radiochemical Analysis (aka ERA14, link here). I found this a fascinating insight into the breadth of applications where radiochemical measurements can help science. I’d naturally assumed the meeting would include major focus on nuclear forensics, but the additional focus on medical applications, fuel reprocessing…
