Gas analysis
A hydrogen tank never looks contaminated. So we measure it.
ppm-level precisionAt Kløfta or on siteGas Analysis Report
01
We take a gas sample from your tank or process line — at Kløfta or at your site.
02
The gas chromatograph separates the mixture and pinpoints every component — down to ppm level.
03
An analysis report with documented purity — the same method that verifies < 300 ppm after flushing.
Valves actuate, pressure builds, sensors report healthy values — and none of it tells you what is actually inside the tank. Purity is invisible. Fuel cells, on the other hand, notice it immediately: contaminants measured in parts per million can be enough to degrade sensitive downstream equipment. Fuel-cell-grade hydrogen requires a minimum hydrogen purity of 99.97 %, with strict limits on individual contaminants. Not much of a margin — which is why we measure throughout the process.
The instrument is a gas chromatograph.
It separates a gas sample and quantifies selected target components — such as nitrogen, oxygen and moisture — down to ppm level. It is the same method we use to verify every one of our own warm flushing and first fill deliveries, so it is not a service we offer on the side. It is the standard our own work has to pass, every time.Where and why we sample.
Samples can be taken from a tank or a process line — at Kløfta, or at your site if the gas cannot come to us. Typical cases: verifying a container after flushing, troubleshooting a purity deviation, checking a supply before it reaches sensitive equipment, or documenting quality in a handover between parties who would both rather have numbers than promises.What you receive.
A Gas Analysis Report with measured results for each target component, backed by calibrated instruments and documented procedures. If the gas meets the specified limits, you have the paperwork to prove it. If it doesn't, you have the diagnosis — and, since flushing happens fifty metres away, a short path to the fix.Measurement is also how we run the place.
Internally we call it Gas-troscopy: using operational data and regular audits to examine not just whether a process works, but how well. The same discipline that keeps our flushing repeatable — the hundredth flush performed exactly like the first — is what your analysis report inherits.Need numbers instead of assumptions?
Send an enquiry describing the tank or gas stream in question, and we will come back with method, timeline and price — normally within one working day.Get in touch
