In analytical laboratories, gas purity is not an option.
Yet, a discreet contaminant can compromise results without being immediately detected:
👉 siloxanes
Often overlooked, these compounds can silently impact analytical performance, instrument stability, and data reliability.
Why Siloxanes Are a Problem
Siloxanes typically originate from silicone-based materials, such as:
- seals
- lubricants
- tubing
- adhesives
They can enter the gas stream even in controlled environments.
👉 In simple terms:
A gas can be technically compliant and still alter analytical results.
Over time, this leads to:
- reduced repeatability
- drift in measurements
- contamination of sensitive components
Gas Generators: Not All Are Equal
In gas generation systems, the risk of siloxane contamination is directly linked to:
- material selection
- assembly processes
- manufacturing discipline
Even minimal use of silicone components can introduce contamination into the gas path.
👉 This is why design philosophy matters as much as performance specifications.
The LNI Swissgas Siloxane-Free Approach
At LNI Swissgas, this issue is addressed at the design level.
Our generators are engineered to avoid contamination risks, through:
✔ strict exclusion of silicone materials along the gas path
✔ systematic qualification of components and suppliers
✔ assembly procedures without silicone lubricants or adhesives
✔ full traceability of critical parts
✔ continuous team training on contamination risks
To date, no siloxane contamination has been reported across installed systems.
Why It Is Essential for Laboratories
Choosing a truly siloxane-free gas solution means:
✔ ensuring analytical quality and repeatability
✔ protecting analytical instruments
✔ reducing unexpected maintenance
✔ guaranteeing compliance, especially in regulated environments
Because in analytical science:
👉 reliability depends on what you don’t see
👉 and purity is part of the measurement system
From Gas Supply to Analytical Confidence
Gas is not just a utility. It is an integral part of analytical performance.
Ensuring its purity means ensuring the quality of every result.
