Gas generators provide a number of benefits

Convenience

Consistency

Safety

Green

Economy

Gas on-demand, no
cylinders to change or
maintain supply stocks

Consistent gas quality
and supply, no impurities
or running out of gas

No pressurized
compressed gas cylinders
in your lab

No repeated gas
deliveries, energy efficient

Eliminate on-going costs
of cylinders, manage
lifetime running costs

Why Precision?
“Gas generators provide a consistent source of gas”
Cylinder quality variation can affect your results
Varying quality from batch to batch can affect baseline
Using the last 10% of the cylinder can introduce impurities into the GC

“A generator provides gas 24/7/365”
Cylinders can run out at the wrong time
Cylinders must be monitored to prevent gas running out
Cylinders running out during evenings or weekends affects workflow

“A generator remains on-site once delivered to the lab”
Cylinders must be repeatedly transported
CO2 emitted through the refilling, conditioning and transportation of cylinders

Why Precision?
“Gas generators are a safe, low volume and
low pressure gas source”
Cylinders and dewars present risks to lab personnel
Handling heavy cylinders risks injury
Pressurized hydrogen cylinders are a potential explosion/fire risk
Pressurised nitrogen cylinders and dewars present an asphyxiation risk

“A gas generator provides a stable cost to labs without
future uncertainty”
Hidden costs of cylinders (traps, pipework, regulators, safety inspections)
increase operational costs
Changing market dynamics can hit lab budgets unexpectedly
Helium availability and price is unstable
