Aiolos III is a high-precision GasMix™ gas mixer, gas diluter and gas blender. It belongs to the GasMix™ family of automated gas mixing systems (GasMixing Systems) used worldwide for generating calibration gas standards directly in the laboratory.
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 GasMixing 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)
Metrological Excellence for Gas Mixers
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.
- NIST-traceable calibration
- ±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.

Most asked questions about multi-line GasMix™ calibration, automation and metrology for gas mixing systems and gas blenders.
What is Aiolos III used for?
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.
How many gas lines can Aiolos III handle?
Aiolos III can handle from 2 to 6 Mass Flow Controllers. The number of channels will depend on the chosen configuration and application requirements.
What concentration range can Aiolos III generate?
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.
How is Aiolos III different from Zephyr or Nomad?
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 as a rack-mounted gas mixer and gas blender.
Does Aiolos III need a PC, or is software embedded?
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.
Is Aiolos III suitable for CEMS and EN 14181?
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.
What gas types are compatible with Aiolos III?
Aiolos III is compatible with pure gases, concentrated mixtures and many aggressive gases, with suitable materials and options.
How accurate is the system and what about traceability?
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.
Can Aiolos III be integrated with analyzers or automation systems?
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.
What maintenance does Aiolos III require?
Routine maintenance is limited to periodic leak checks, filter inspection or replacement and scheduled recalibration of the MFCs according to your QA plan. For aggressive matrices, more frequent checks of surfaces and seals may be recommended.
Is Aiolos III suitable for hydrogen applications?
Aiolos III can be configured with MFCs and materials compatible with hydrogen and hydrogen-containing mixtures. For pure H2 or high-pressure / high-concentration hydrogen use, a dedicated hydrogen-ready configuration is recommended.
Is Aiolos III a gas mixer or a gas blender?
Aiolos III works as both. It is a dynamic gas mixer and gas diluter that can also be used as a fully automated gas blender within complex analytical systems. This means one GasMix™ unit can replace several manual gas blenders and flow panels.
