In modern analytical and industrial workflows, gas calibration is just as important as gas generation. While on-site gas generators improve laboratory safety, continuity, and cost efficiency, a robust calibration strategy ensures measurement accuracy, traceability, and confidence in analytical results.
At LNI Swissgas, our calibration systems — led by the Sonimix 2106 gas mixer — are designed to deliver highly accurate dilution flows, metrological performance, and operational versatility that drive reliable calibration across a wide range of applications.
Why accurate dilution flows matter
Calibration is the process of linking instruments and measurement devices to known reference standards. In gas analysis, particularly for gas chromatographs (GCs) and other detectors, calibration must be precise so that instruments deliver valid, repeatable results. A calibration device that produces consistent and traceable gas mixtures reduces uncertainty and supports compliance with quality systems and regulations.
Without accurate dilution flows:
- results can drift over time
- instruments may perform inconsistently
- compliance with standards and regulations becomes more difficult
Sonimix 2106 — Precision Meets Performance
The Sonimix 2106 gas mixer from LNI Swissgas represents a class-leading solution for gas calibration based on sonic nozzle technology — a proven method that ensures stable, accurate dilution across a wide range of mixtures.
Key advantages include:
📏 Highly accurate concentration levels
The sonic nozzle principle enables binary gas mixtures with concentration accuracy within ±0.5% of setpoint, with consistent flows generated in fixed mechanical steps — without electronic regulation and unaffected by ambient temperature or pressure changes.
🔄 Exceptional stability and repeatability
Sonimix 2106 provides repeatability of flow below 0.1% and concentration repeatability better than 0.14% relative — critical metrics for confidence in calibration and analytical repeatability.
📊 Wide dilution range and automation
With support for up to 1,024 programmable setpoints, Sonimix 2106 is ideal for complex calibration sequences and automated routines. Its touchscreen interface and remote connectivity (Ethernet, USB, RS-232) simplify integration into laboratory automation and QC systems.
🛠 Operational benefits
- Reduced reliance on multiple certified gas cylinders
