NEPHOS — Liquid-to-Gas Mixer

NEPHOS covers a very wide range, from percent-level vapors down to trace and ppb levels. When equipped with optional cascade dilution, the overall dilution factor can reach up to 10⁸, depending on configuration and application.

NEPHOS is suitable for many organic solvents and VOC mixtures (e.g. BTEX, siloxanes, alcohols, phenols) and, in dedicated configurations, water or aqueous solutions. Final compatibility depends on volatility, viscosity and material compatibility; our team can review your liquid list and propose the appropriate configuration.

No, NEPHOS is designed to generate gas standards directly from liquids using a carrier gas. It can also be combined with existing gas standards or GasMix™ platforms when you want to mix liquid-derived components with gas-phase standards in the same stream.

Vaporization takes place in a controlled, heated chamber and the transfer path to the outlet is heated to maintain the gas phase. This minimizes the risk of condensation, especially for higher-boiling components, and improves repeatability at low concentrations.

Yes, on request NEPHOS can be built with inert-grade wetted materials (SS316, inert coatings, Kalrez® seals) for aggressive or reactive compounds. For highly corrosive or unusual chemistries, we recommend providing details so we can check material compatibility and lifetime.

NEPHOS relies on 400-point calibrated MFCs, NIST-traceable references and LiqMix™ software. The software calculates concentrations, manages sequences, logs all critical events in an Audit Trail and can generate certificates including calculated concentrations and uncertainties for QA/QC documentation.

A typical installation requires electrical power, a suitable carrier gas supply (e.g. nitrogen, air or other matrices depending on your application) and proper ventilation or exhaust according to the compounds used. Exact requirements are specified in the technical documentation.

Yes. LiqMix™ can synchronize sequences with GC, preconcentrators, spectrometers and other gas analyzers using digital I/O and timing parameters. This allows fully automated calibration routines with minimal operator intervention.

Yes. NEPHOS generates traceable, reactive-compound and humid standards suitable for analyzer checks and validation in emission-monitoring workflows. Tell us your components and regulatory framework and we’ll confirm the configuration.

NEPHOS meters liquids with a Coriolis mass flow meter, measuring true mass independent of density, viscosity or temperature — so you can change fluids without re-tuning. It states a < 2 % concentration accuracy, is ISO 6145-7 compliant, and issues a certificate with uncertainty for every point. Many peristaltic or syringe-pump generators dose by volume and do not publish an accuracy figure.

Yes. NEPHOS vaporizes water and aqueous solutions to generate humid calibration gas alongside your target compounds. Its design prioritizes certified concentration accuracy; for applications requiring very long-duration humidity stability, contact us to confirm the right configuration.

A Coriolis meter measures the actual mass of liquid delivered, unaffected by the fluid’s density, viscosity, temperature or conductivity. This means accurate, repeatable standards across different solvents and mixtures without recalibrating the dosing each time you change liquid — an advantage volumetric pumps cannot match.
