Gas Supply in Chromatography

In chromatography, gas quality is not just a utility issue — it directly impacts instrument uptime, method stability, and operational efficiency.

For many laboratories, compressed gas cylinders have been the traditional choice for supplying nitrogen, hydrogen, or zero air. But the challenges are well known:

• Cylinder changes during busy workflows
• Risk of supply interruptions mid-sequence
• Manual handling and storage requirements
• Recurring rental, transport and delivery costs
• Variability in logistics and market pricing

That is why an increasing number of labs are moving toward on-site gas generation solutions such as those from Peak Scientific.

A modern gas generator produces the required gas on demand, directly at the point of use. For chromatography users, this can deliver several practical advantages:

Consistent Supply
No more unexpected empty cylinders during critical runs. Continuous gas availability helps reduce downtime and rescheduling.

Stable Purity & Performance
Reliable gas purity supports reproducible analytical performance in LC-MS, GC and GC-MS workflows.

Improved Laboratory Safety
Generators reduce the need to store and move high-pressure cylinders around the lab environment.

Lower Total Cost of Ownership
While generators require upfront investment, many labs see savings over time by reducing cylinder rental, transport and delivery expenses.

Sustainability Benefits
On-site generation can help lower the environmental footprint associated with repeated cylinder deliveries.

At Nordic Biolabs, we are proud to support laboratories with Peak Scientific solutions designed for modern analytical workflows.

If your lab still relies fully on cylinders, it may be worth asking a simple question:
Are we buying gas… or buying inconvenience?
