Combining low-cost single board computers with open-source software to control noble gas extraction lines

Specialised mass spectrometers such as those used in noble gas geochemistry are often controlled by bespoke computer systems that get harder to maintain as, along with their expensive interface cards, they become obsolete. This work explains how bespoke interface cards and obsolete versions of software can be replaced with low-cost single board computers and open source software. Although tailored to an ultra-high vacuum helium extraction line the basic elements and microservices detailed in this paper provide a template for controlling a wider range of instruments. • Moving from obsolete computer hardware to current hardware. • Moving from licenced proprietary software to opensource software. • Automating processes to reduce process time and manual steps.
