Helium is a rapidly-dwindling, non-renewable resource, so it is becoming more difficult to source, which has led to disruption in supply, and more expensive to purchase. There are many benefits to switching to Multi-Gas enabled thermal desorbers. Being able to use hydrogen as a carrier gas instead of helium, for example, has the following benefits.
Enchanced Productivity
Hydrogen offers faster chromatographic separations, shorter TD methods and lower-temperature separations than helium, drastically increasing laboratory throughput, extending consumables’ lifetimes and extending maintenance intervals.
Hydrogen viscosity is about half that of helium, enabling it to be used at faster flow rates (linear gas velocities) without compromising chromatographic resolution.
Cost&Time Saving
Switching from helium to hydrogen saves up to 90% per cylinder.
A hydrogen generator eliminates the costs of cylinders together with their delivery, rental and system maintenance, and the need to install expensive pressurised gas supply lines and cylinder cages in new or refurbished laboratories.
Superior analytical performance
Hydrogen carrier gas routinely produces high-quality data and delivers results that comply with global tube-based TD–GC–MS standards.
Multi-Gas enabled TD instruments allow re-collection and repeat analysis to eliminate data loss, confirm results and validate analyte recovery in compliance with international standard methods.
Convenience
Hydrogen generators provide consistent, high-quality carrier gas on demand, eliminate the risk of downtime due to delayed carrier gas cylinder deliveries and reduce reliance on personnel trained to change the cylinders.
Generators are ideal for remote, difficult to access or mobile laboratories.
Green Techonology
High-purity hydrogen can be generated from water, providing a sustainable carrier gas supply. Helium, on the other hand, is non-renewable and needs to be extracted, shipped and stored using specialist equipment, causing significant environmental impact.
An in-house generator eliminates the need for cylinder deliveries, significantly reducing the laboratory’s carbon footprint.
Future-proofing
Multi-Gas thermal technology safeguards laboratory operations against the rising costs of high-purity helium.
Multi-Gas desorbers enables the development or transfer of methods using hydrogen as a carrier gas as workload and requirements evolve.
