Liquid-to-Gas Standard Generator — from % to ppb
From liquids to traceable gas standards — on demand.
NEPHOS is AlyTech's latest evolution in the LiqMix™ range — a bench solution that produces custom gas standards directly from pure or mixed liquids. Optional cascade dilution unlocks an exceptionally wide concentration span, from percent down to ppb.
The instrument precisely vaporizes up to two liquid phases into a controlled carrier gas stream, generating mixtures on demand with full traceability. A modular architecture lets your system evolve as requirements grow — ideal for QA/QC, method development and analyzer validation.
Heated transfer paths up to the delivery point prevent re-condensation, ensuring a clean, stable gas phase for accurate, repeatable measurements.
NEPHOS combines a Coriolis-type liquid flow meter with a precisely regulated vaporization chamber. Mass Flow Controllers (MFC/RDM) deliver repeatable dilutions, while heated lines maintain the gas phase to the outlet. All controlled via LiqMix™ software:
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. Dilution factor up to 10,000 per stage — up to 10⁸ with cascade option.
