AIOLOS III

Dynamic Gas Mixer & Diluter — 2 to 6 channels, ISO 6145-7 compliant

AIOLOS III Gas Mixer Diluter

20+ years of GasMix™ expertise — third generation.

2 to 6 Channels ISO 6145-7 Audit Trail Cascade Dilution Up to 10⁸ Dilution Aggressive Gases Ready Analyzer Sync

System Concept

AIOLOS III is the third-generation GasMix™ dynamic gas mixer, gas diluter and gas blending system from AlyTech, designed 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. It 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, 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 AlySoft™ 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 and validation
  • Event logging and Audit Trail for complete traceability
  • Certificate issuance with concentrations & uncertainties
  • Options: Injection Valve, FReD flow regulator, Cascade, Multiplexer

Key Benefits

  • Dynamic Mixing — flexible generation of standards from 2 to 6 gas channels
  • High Accuracy — 400-point MFC calibration curves applied per gas matrix
  • Full Automation — sequences + analyzer sync minimize operator time and gas consumption
  • Traceable by Design — certificates, uncertainty reports and full Audit Trail for every blend
  • ISO 6145-7 — proven compliance for calibration in regulated environments
  • Customizable — injection valve, FReD regulator, heated lines, multiplexer and more

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, CO₂…). NIST-traceable calibration, ±1% accuracy, <0.1% repeatability. Automatic K-factor calculation & correction. Dilution factor: 10⁴ in standard — up to 10⁸ with Cascade option.

Typical Applications
