Hiden Analytical is highlighting the DLS-2 and DLS-2X as key systems for nuclear fusion gas analysis within its DLS Series. Designed for fusion fuel studies, vacuum diagnostics and leak detection, the systems combine Dual Zone mass spectrometry, high-resolution gas separation and quantitative residual gas analysis in a single platform, while the DLS-2X adds features for reliable operation in harsh environments.

At the heart of the DLS-2 and DLS-2X is Hiden’s unique, software-selectable Dual Zone operation, allowing users to switch between Zone 1 and Zone H not just within the same instrument, but within the same experiment. This enables ultra-high-resolution analysis for closely spaced species, including applications such as detecting helium in deuterium, while maintaining strong residual gas analyser performance for routine vacuum diagnostics in Zone 1.
For fusion research teams, the DLS-2 and DLS-2X improve separation of hydrogen isotopes, helium and deuterated compounds while supporting reliable quantitative gas analysis for fuel studies, vacuum diagnostics and plasma-facing system research.
“The DLS-2 and DLS-2X demonstrate what the DLS Series is built to deliver: clearer answers in demanding gas analysis applications,” said Bob Mellor, Principal Electronics Engineer at Hiden Analytical. “Our Dual Zone technology gives fusion researchers a unique way to resolve overlapping species without sacrificing the quantitative data they need to understand complex processes with confidence.”
Available in two configurations, the DLS-2 / DLS-2X platform offers high-resolution Zone H up to 22.5 amu with 0.02 amu real-time mass separation plus standard-resolution Zone 1 up to 100 amu, or ultra-high-resolution Zone H up to 10 amu with 0.0065 amu real-time mass separation plus standard-resolution Zone 1 up to 44 amu. The systems also deliver 10 ppm sensitivity for both He in D2 and D2 in He, while the DLS-2X supports remote analyser mounting up to 140 m from sensitive electronics, making it particularly well suited to fusion applications and other harsh operating environments.
As part of the wider DLS Series, the DLS-2 and DLS-2X reinforce Hiden Analytical’s position in advanced gas analysis for fusion research. By combining high-resolution mass separation with dependable quantitative measurement, these systems give laboratories a practical way to move beyond simple detection and towards more accurate, more meaningful interpretation of complex gas mixtures.
