System Concept
AIOLOS III is AlyTech’s third-generation of GasMix™ dynamic gas mixer and diluter, 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. Its modular, customizable design lets you tailor configurations for 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.
Operation & Software
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.
- Programmable sequences for dilution, injection and flushing
- Analyzer synchronization for automated calibration
- Multi-point calibration
- Event logging and Audit Trail for complete traceability
- Options: Injection Valve, FReD flow regulator, 2nd stage dilution mode (Cascade)
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.
- 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.
What is Aiolos III used for?
Aiolos III is a multi-channel GasMix™ system for dynamic preparation of gas standards. 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 is typically configured with multiple Mass Flow Controllers to handle several gas inlets (standard and diluent gases). The exact number of lines depends 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 trace levels up to high-level calibration points. Multi-point curves for linearity checks and span/zero calibration can be generated automatically.
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 is a multi-line rack/bench system designed for complex mixtures, simultaneous feeds and advanced calibration scenarios. Nomad focuses on mobile, field-ready GasMix™ applications, whereas Aiolos III is optimized for laboratory or fixed installations.
Does Aiolos III need a PC, or is software embedded?
Aiolos III is controlled by GasMix™ software, which can be run from a built-in interface (depending on configuration) and/or 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 a wide range of non-corrosive and reactive gases used for calibration (e.g. CO, CO₂, NOx, SO₂, H₂S, hydrocarbons, VOC). For aggressive or highly reactive gases, dedicated materials and sealing options can be specified.
How accurate is the system and what about traceability?
Each MFC is factory-calibrated and characterized across its flow range. 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, 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.
