GASMIX™ PLATFORM
Gas Mixer and Gas Diluter for Precise Gas Blending and Calibration - Aiolos III
Dynamic Gas Mixer & Gas Diluter, 2 to 6 channels, ISO 6145-7 compliant
AlySoft™ software — unified control, sequences, analyzer sync and full Audit Trail for your gas mixing system.
Aiolos III is a high-precision GasMix™ gas mixer and gas diluter. It belongs to the GasMix™ family of automated gas mixing systems used worldwide for generating calibration gas standards directly in the laboratory.
System Concept
AIOLOS III is the third-generation GasMix™ dynamic gas mixer, gas diluter and gas blending system from AlyTech, designed by engineers & chemists to generate calibration gas standards directly on site — from percent down to trace levels. By mixing and/or diluting two to six gases, Aiolos III delivers precise, reproducible concentrations with full traceability and certified metrological accuracy.
Developed and manufactured in France, the instrument builds on 20+ years of GasMix™ experience in laboratory and industrial gas preparation. As a result, this gas mixing system can act as a central gas blender for complex multi-analyzer benches, supporting multi-point calibration, linearity checks, LOD/LOQ validation, research studies and more.
Compact and robust, and compliant with ISO 6145-7, Aiolos III ensures dependable performance for laboratories that demand accuracy, flexibility and long-term reliability from their gas mixer and gas diluter.
Operation & Software for Gas Mixing Systems
Aiolos III is operated via dedicated GasMix™ software, providing unified control of channels, flow parameters and sequences through an intuitive interface. The platform performs all calculations — mixture ratios, dilution curves and documentation — and synchronizes with external analyzers for fully automated routines on your gas mixer and gas diluter.
Programmable sequences for dilution, injection and flushing
Analyzer synchronization for automated calibration
Multi-point calibration and validation
Event logging and Audit Trail for complete traceability
Options: Injection Valve, FReD flow regulator, 2nd stage dilution mode (Cascade), Multiplexer...
High-Accuracy Gas Mixing and Metrological Excellence
Every integrated Mass Flow Controller (MFC) undergoes 400-point factory calibration across the full dynamic range and for each selected gas matrix (He, Ar, CH4, H2, N2, Air, …). This ensures superior linearity and precision, especially at very low and very high flow rates.

±1% set point accuracy and <0.1% repeatability *
Automatic K-factor calculation & correction
Dilution factor: 104 in standard — up to 108 with Cascade
Automatic uncertainty calculation, full QA/QC traceability with Audit Trail
Certificate issuance with concentrations & uncertainties
* When MFCs operate between 10% and 100% of full-scale flow.

FAQ — AIOLOS III Gas Mixer & Gas Diluter
Most asked questions about multi-line GasMix™ calibration, automation and metrology for gas mixing systems and gas blenders.
Aiolos III is a multi-channel GasMix™ gas mixing system. As a gas mixer and gas diluter, it blends and dilutes several certified gases with a diluent gas to generate calibration mixtures for GC/µGC, process analyzers, CEMS and R&D applications.
Aiolos III can handle from 2 to 6 Mass Flow Controllers. The number of channels will mainly depend on the application requirements.
Thanks to dynamic dilution and multiple MFCs, Aiolos III can cover a very wide concentration range, from percent levels down to trace levels. In standard configuration Aiolos III can dilute up to 104, and up to 108 in cascade mode.
Zephyr is a compact two-gas mixer/diluter, ideal when only one standard gas and a diluent are required. Aiolos III can have up to 6 channels and is customizable with many different options (cascade, FReD, heated lines, multiplexer, etc.). Nomad focuses on mobile, field-ready GasMix™ applications, whereas Aiolos III is optimized for laboratory or fixed installations.
Aiolos III is controlled by AlySoft software, which is run via an external PC. The software allows you to build methods, Smart Sequences, log all events and export full reports for QA/QC and audits.
Yes. Aiolos III is designed for high-accuracy calibration and can support multi-point linearity checks, QAL3 routines and periodic calibrations in line with EN 14181 and similar requirements, when paired with appropriate certified gases.
Aiolos III is compatible with pure gases, mixtures and many aggressive gases such as H2S, NH3, HF, NOx, VOC and more.
Each MFC is factory-calibrated and characterized across its entire flow range. Flow accuracy is typically better than 1% of the requested value and repeatability is better than 0.1%. Combined with ISO 6145-based dilution and uncertainty calculation within the software, Aiolos III offers high accuracy and full traceability from parent cylinder certificate to final mixture.
Yes. Aiolos III can synchronize with analyzers via digital signals (such as dry contacts/TTL or Modbus, depending on configuration) and can be integrated in automated test benches. GasMix™ software allows remote control, method scheduling and data export.
Thanks to its robust design, the Aiolos III is virtually maintenance-free. We simply recommend a performance verification of the MFCs every 24 months to prevent any drift and ensure continuous compliance with ISO 6145-7 standards.
From percent levels down to ppb traces, the Aiolos III is the system of choice for ISO 14687-2 compliant calibration. It is already deployed in H2 labs to monitor critical impurities, guaranteeing the high-purity hydrogen required for fuel cell applications. See more in our application note section.
