Why gas generators?
No more cylinder changes, delivery slots or high pressure in the lab.
A generator produces exactly the gas your instrument needs – around the clock, at consistent purity. No storage, no rental fees, no downtime because a cylinder ran empty.
Safe
No storing or moving high-pressure cylinders, no stock of flammable hydrogen in the lab.
Cost-efficient
No fluctuating gas prices, delivery or rental fees. Minimal maintenance and a short payback time.
Always available
Gas on demand, 24/7. No more stopped sequences because a cylinder ran out overnight.
Better results
Consistently high purity and stable pressure – for flat baselines, sensitivity and reproducibility.

Frequently asked questions
What labs want to know before they buy.
Your question isn't listed? Get in touch – we'll be happy to advise you.
- What is the SCHMIDLIN Smart Box?
The SCHMIDLIN Smart Box is an innovation by SCHMIDLIN and the link between your hydrogen generator and maximum operational reliability. It monitors the generator around the clock, detects anomalies instantly and reports not just an “error”, but the exact fault code with context data – so our service team can act precisely. All sensor data such as cell voltage, temperature, system pressure and flow rate feeds into a digital twin that calculates the remaining life expectancy of the H2 stack. With the SCHMIDLIN App you also get instant access to all sensor data via USB. Learn more about the SCHMIDLIN Smart Box.
- Is a hydrogen generator safe in the lab?
The generator produces hydrogen on demand from deionized water – you store neither high-pressure cylinders nor a stock of flammable hydrogen in the lab. Integrated sensors shut the generator down automatically in the event of internal or external leaks, contaminated water, low water or overpressure. VICI DBS generators are certified to CE, FCC and MET (UL and CSA compliant). Learn more about our hydrogen generators.
- What purities and flow rates are available?
Depending on the model, our hydrogen generators deliver up to 1350 mL/min at up to 99.99996 % purity – a single NM Plus supplies up to 33 GCs. Depending on the model, nitrogen generators reach up to 120 L/min in LC/MS quality, and zero air generators up to 30 L/min. Find the right unit for your gas demand in our generator overview.
- Which applications are the generators suited for?
Hydrogen serves as carrier and fuel gas for GC and FID, nitrogen is used for LC/MS, sample preparation and GC, and zero air as hydrocarbon-free air for FID and analyzers. Our generators also supply test benches and the development of fuel cell systems, as well as universities, institutes and teaching labs. See the overview of applications.
- What service does SCHMIDLIN offer – also after the purchase?
We take care of consultation, installation and commissioning as well as on-site maintenance and repair in Germany and Austria. A service contract includes regular maintenance, preventive maintenance measures and fast response times in case of repair. If a unit fails, our exchange service keeps your lab running, and our well-stocked spare parts store keeps downtime short. With the SCHMIDLIN smart ecosystem of Smart Box, digital twin and SCHMIDLIN App, maintenance becomes predictive: service intervals are based on the actual condition of the components instead of rigid schedules, and gradual deviations are detected before they lead to a failure. All services on our service page.
- How sustainable and economical is a gas generator?
Because the gas is produced right on site, regular gas deliveries and cylinder changes are eliminated – reducing your lab's ecological footprint. At the same time, you are independent of fluctuating gas prices, delivery and rental costs, and maintenance effort is minimal. We'll gladly calculate when a generator pays off for you – just ask us.
