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.
