The LiqMix NEPHOS is based on the proven technology of mass flow controllers (MFC) for gases and Coriolis for liquids. These MFCs are factory calibrated using NIST-traceable procedures. The Coriolis flowmeter can handle all kinds of liquids, pure or in solution, regardless of the conditions of its environment (temperature, pressure, density, conductivity and viscosity). The vaporization temperature is controlled by the software. The liquid phase, thus vaporized, is pushed by a vector gas. This gas stream can be further diluted and/or mixed with other gases (up to 4 additional channels possible) and/or a second vaporized liquid. It is then possible to generate complex mixtures over a very wide range of concentrations with many compounds. The gas lines are heated in order to avoid any point of re-condensation and to maintain the whole in the gaseous state until the point of delivery.
AlyTech LiqMix™ NEPHOS
From liquids, generate your gaseous mixtures at the desired concentrations
Some applications require gas mixtures or standards that are not commercially available in cylinders. LiqMix™ Nephos, developed by AlyTech, is a dynamic system that custom generates these standard gases from pure liquids or mixtures of liquids.
The instrument vaporizes the liquid phase in a gas stream, generating a custom gas standard, of multiple concentrations and in a faithful and accurate manner. The production of a standard gas then benefits from full traceability and quality monitoring thanks to the associated software. The software, developed by AlyTech, allows you to create sequences, to have quality monitoring and can be synchronized with third-party instruments such as GC, a spectrometer, a preconcentrator, a gas analyser, or any other instrument.

Application spotlight: Biogas Valorization
Siloxanes are transformed into silicon oxides at high temperature. These oxides are very hard materials which can damage the metal surfaces of an engine. Gas chromatography is used to evaluate the efficiency of a siloxane remover process. The analyzer must be calibrated and gas standards containing Siloxanes are not commercially available. LiqMix is used to vaporize octamethylcyclotetrasiloxane (D4) which is liquid at room temperature,
