Research, testing and measurement laboratories are a defining feature across the broadest range of industries – from automotive and power through petrochemicals and pharmaceuticals to environmental protection. In fact, just about everything we eat, drink and use has been analyzed at some point in its lifecycle. Regardless of what they are analyzing or testing, all laboratories have one thing in common. They are aiming for precision and often rely on high-purity process and calibration gas mixtures to achieve this.
Helium is the most commonly gas used as carrier in gas chromatography.
Under liquid state, at -269 °C, helium is the cooling fluid for the MRI, NMR or EPR magnets.
