  • Isotopes 101

    Isotopes 101

    When we talk about our instrumentation, it’s with the goal of measuring various isotopes… but not all isotopes are created (or destroyed) equally! This is a summary of isotopes in terms of longevity, abundance, and elemental behavior. When people think of isotopes they often think of nuclear plants… but what makes certain isotopes useful for…


  • Do all mass spectrometers go to heaven: What does it take to recycle an Isotope Ratio MS?

    Do all mass spectrometers go to heaven: What does it take to recycle an Isotope Ratio MS?

    This may be upsetting to some of our readers, but the reality is no mass spectrometer can produce data forever (*sobbing into lab coat*). While this can be difficult to accept, rest assured that it’s not over for your geochemically enthusiastic instrument… in fact it’s just the beginning! Here we explore exactly what parts of…


  • Isotope Ratio MS – Do Looks Matter?

    Isotope Ratio MS – Do Looks Matter?

    I sometimes attend product development meetings at Isotopx. The subject of instrument design, by which I mean the “aesthetic values” of our products are quite often a subject of discussion. If you know your historic isotope ratio instruments, you’ll know that until relatively recently they been a triumph of function over form, with sometimes an…


  • Why are some mass spectrometers Dual Use?

    Why are some mass spectrometers Dual Use?

    If you work in the Earth sciences, as many of our users do, then you probably don’t come across the term “Dual Use” very often, if at all. Yet for the vendors that supply this community, it is a very significant term and has a large effect on where we supply our instruments to. I…


  • ATONA Technology – would it work on other instruments?

    ATONA Technology – would it work on other instruments?

    If you have been following my blogs or have taken an interest in detector technologies, then you probably know about ATONA technology already. If you’re not familiar, then for a short overview try here. In brief, ATONA is a Faraday amplifier system that avoids many of the major disadvantages of traditional resistor-based amplifier systems, in…

  • Video introduction to ATONA technology

    We publish a new video that gives a high-level introduction to one of our key technologies – ATONA Our key Faraday technologies, ATONA and Zeptona, are described in a new video. This short “explainer” video is designed to give someone unfamiliar with these technologies an introduction to why they are so different from more traditional…


  • AGU Fall Meeting 2023, San Francisco

    11th – 15th December 2023 San Francisco, USA We are pleased to announce that Isotopx will be attending AGU 2023 which will be taking place from 11 December – 15 December 2023 in San Francisco, California. For more than 100 years AGU has been opening pathways to discovery, opening greater awareness to address climate change,…


  • Femtogram-level analysis of 90Sr using Phoenix TIMS

    Showcasing excellent data from Norbert Kavasi and the team at Fukushima Institute for Research, Education and Innovation Phoenix TIMS users Norbert Kavasi and Sarata Kumar Sahoo and team have been working hard to measure low levels of 90Sr, typically in environmental samples or food and beverage samples. 90Sr is an anthropogenic isotope produced in relatively…
