  • The mass spectrometers built to last!

    The mass spectrometers built to last!

    I’m recently back from a sales trip to China and Japan, and several things struck me whilst travelling. First was the pace of change, especially in China – where the level of visible wealth has increased significantly, in the cities I visited at least. The second thing was the number of old but well-maintained noble…


  • Cultural mishaps of a mass spectrometrist

    Cultural mishaps of a mass spectrometrist

    At the time of writing this blog it’s only a couple of weeks until I head out on a business trip to China and Japan. Although I used to travel a bit when I was younger, it doesn’t happen so much these days, especially in the last three years (for the unmentionable reason). But I…


  • Who would be an installation engineer?

    Who would be an installation engineer?

    In the world of analytical instrumentation, it’s quite a well-trodden path to move from test and installation engineering to marketing, sales or product management. It’s the route that I took myself, along with a number of my colleagues here at Isotopx. But why does this happen so commonly, what is it about test and installation…


  • Should I consider leaving academia for the commercial world?

    Should I consider leaving academia for the commercial world?

    Many of our customers, past, present and future, are highly successful academics. Therefore, the question about consideration of a career in the commercial world is a contentious one at best. I’m guessing that the majority of people in our sphere that see the abovementioned question will have a pretty clear answer in mind. But there…


  • Why should I use a degasser with my TIMS?

    Why should I use a degasser with my TIMS?

    Much of my mass spectrometry experience has been associated with ICP-MS so I’m far from an expert in thermal ionization mass spectrometry (TIMS), meaning every day can be a school day at Isotopx. Today I was wondering about filament preparation techniques such as carburization to increase efficiency of small samples. However, I thought I’d first…

  • An introduction to Zeptona technology

    Interested to learn about Zeptona technology? It’s a technology based on ATONA, but takes it one step further. It’s well suited to a number of isotope ratio measurement applications, particularly those in U-Pb geochronology. Click here to take a look at the short article that introduces Zeptona, and get in touch if you want to…
