How does the Sonimix 2106 reduce operational costs?

By generating multiple concentrations from one high-concentration gas cylinder. The Sonimix 2106 reduce the number of cylinders required, lowers inventory costs, and simplifies gas logistics.

Which LNI Swissgas solution is best suited for calibrating gas analyzers, gas sensors, or gas detectors?

LNI Swissgas offers several calibration solutions depending on the application.

The Sonimix 2106 and Sonimix 7100 generate accurate gas concentrations through dynamic dilution from gas cylinder. While the Permacal generates trace-level concentrations of reactive compounds such as NH₃, HCl, HF, HBr, VOCs, and hydrocarbons from permeation tubes.

Together, these solutions cover a wide range of gas analyzer, sensor, and gas detector calibration applications.

Why use a gas mixer or a permeation system instead of single gas cylinders?

Permeation systems or gas mixer allow users to generate multiple concentration levels on demand from a single source gas cylinder or permeation tube. This reduces the number of calibration cylinders required, lowers operating costs and simplifies logistics.

They also provide exceptional flexibility for multi-point calibrations and linearity checks. Concentration setpoints can be adjusted quickly and accurately across the analyzer’s, sensors’s or detector’s measurement range, making it easy to verify instrument linearity, response, and performance without changing cylinders.

This saves time while improving calibration efficiency, traceability, and repeatability.

Can we have a NOx converter tester and a gas divider in the same unit?

The Sonimix 2106 combines Sonic Nozzle dilution technology with a relative uncertainty below 0.5%, allowing highly accurate generation of multiple calibration concentration points from a single source gas.

Designed for automotive emissions testing, the instrument can also integrate a NOx Converter Tester, offering a compact all-in-one solution for NOx analyzer calibration and converter efficiency verification.

This simplifies testing procedures while ensuring reliable and traceable results.

What are the added value of the Sonic Nozzle for UHP applications?

The Sonimix 2106 is based on Sonic Nozzle technology, which provides a dilution ratio uncertainty of less than 0.5% (relative). This enables highly accurate and repeatable concentration generation.

In UHP and specialty gas applications, uncertainty becomes increasingly important as concentration levels decrease. At ppm and ppb concentrations, even minor flow uncertainties can result in significant concentration deviations.

Thanks to the very low uncertainty of Sonic Nozzle technology, the Sonimix 2106 delivers highly accurate dilution ratios, ensuring reliable generation of ultra-low concentrations with outstanding traceability, repeatability, and confidence in the generated gas mixtures.

The stability of the Sonic Nozzle over time also reduce the risk of drift.

Is the Sonimix 2106 suitable for ppm and ppb applications?

Yes, the Sonimix 2106 is designed to accurately generate concentrations at ppm and ppb levels, making it ideal for specialty gas and UHP applications.

Why use the Sonimix 2106 if we already produce certified gas cylinders?

The Sonimix 2106 complements gas cylinder production by allowing users to generate multiple concentration levels from a single source gas. It is ideal for R&D, quality control, analyzer validation, and customer demonstrations.

What technology is used (MFC, sonic nozzles, hybrid systems)?

The technology used will depend of the products. In the Sonimix 2106 we use exclusively the Sonic Nozzle to generate a gas mixture. In the Sonimix 7100 we use exclusively MFC’s to generate a gas mixture. In other product we sometime combine both to manage the gas flow.

How many calibration points can it automatically handle for analyzer linearity verification?

Depending of the use technology, we can start from 10 points and go up to an infinite number of points.

Does the system generate static or dynamic gas mixtures?

Our system are dynamic gas mixer.

When is it better to choose a Sonic Nozzle based system over MFC’s?

Sonic Nozzles are significantly more accurate than Mass Flow Controllers (MFCs). The uncertainty of the resulting gas concentration is typically below 0.5% relative, whereas an MFC-based system generally provides an uncertainty of around 1.5% relative.

Sonic Nozzle technology is therefore preferred for applications requiring highly accurate and repeatable gas mixing, particularly in calibration, metrology, specialty gas and UHP applications.

Calibrator or gas mixer: which one should you choose based on your application?

The term “calibrator” is often used when the primary application is the calibration of a gas analyzer or sensor. The term “gas mixer” is more commonly used when the objective is to generate a specific gas mixture.

Generating a gas mixture can serve different purposes, such as supplying an instrument, simulating a process gas or calibrating an analyzer or sensor. In many cases, a gas mixer and a calibrator are essentially the same device, with the terminology depending mainly on the intended application.

Is it suitable for audit or official regulatory inspection environments?

Yes, all systems can be linked to the national standards.

Does the system require periodic maintenance or frequent recalibration?

The Sonic Nozzle technology provides unmatched stability, resulting in minimal drift and a recommended service interval of two years.

Does the system reduce logistics and gas storage costs?

Yes, our gas mixer helps reduce the number of gas cylinders required. Using a single high-concentration gas cylinder, the gas mixer can generate multiple concentration levels by dilution with a carrier gas.

This reduces the number of cylinders needed, lowers costs, and simplifies the associated logistics and cylinder management.

Can the system operate in continuous mode (24/7)?

Some customer are running our system in their production (24/7), no problem.

Is the system suitable for reactive gases or low concentration ranges?

Yes, thanks to special coatings.

Are gas-contact parts treated to prevent adsorption or contamination?

Yes, we have different type of coating to prevent adsorption/contamination depending of the use gas.

Can it handle high-purity gases without signal degradation?

Yes, coating really help to prevent adsoprtion on the wetted parts which help to avoid contamination.

Does the calibrator generate gases independently or does it dilute certified cylinder gases?

Permeation system are generating trace of gas at ppb level from permeation tubes. Gas mixer are generating mixture from multiple gas cylinder.

Can the system send status signals (Ready/Fault) to the analyzer to synchronize calibration phases?

Yes, there is an autostart function to synchronize the calibrator with an analyzer.

Can an internal calibration check be performed without removing the instrument from the rack?

Yes, on some system we have an Autocal option.

Can solenoid cylinder switching valves be directly controlled via the software?

Yes, all valves within the system are controlled automatically by the software.

Does the software log all events (flows, cylinder changes, errors) to ensure traceability and audit compliance?

Yes, the log allows to track the operational events.

Is it possible to program automatic multi-point calibration sequences?

Yes, all devices include a sequence mode which allows to build a calibration sequence to automatize a calibration process.

Is an accredited calibration certificate provided for the entire system?

LNI Swissgas is accredited according to ISO/IEC 17025 for flow measurement calibrations. An ISO/IEC 17025 calibration certificate can be supplied with every device.
