NOMAD - New portable gas mixer/diluter from AlyTech

The popular GasMix™ technology is now available for field auditors, quality assurance technicians, laboratory researchers, CEM operators and air monitoring station operators who perform calibrations and verification of gas analysers at remote locations. New GasMix™ NOMAD is a compact and versatile instrument assisting you in routine quality procedures where you need it: in a lab, in a mobile lab or at a customer site.

Packaged in a rigid case, equipped with built-in industrial PC and large touch screen the diluter operates under dedicated GasMix™ Windows software. Made by experts, the user-friendly and intuitive software allows creation, modification, and storage of unlimited number of mixing/diluting projects, including not only a gas generation sequences, but also library of gas standards, MFC calibration tables, user settings, external analyser control parameters, and more.

Like all other GasMix™ diluters the NOMAD can handle pure gases, concentrated gas mixtures, most of aggressive and reactive gases like sulfur compounds, or ammonia at trace level. A typical configuration includes 4 gas channels, that allows connection of 2 span gases, interference gas and dilution gas. In this setup, the NOMAD is a full featured tool for multi-point span and zero calibrations, linearization, repeatability check, purity check, interference check and other applications. No need for manual computations, the operator defines concentrations of calibration points and the software calculates flow rate of each channel considering the initial concentration of parent gas and the range of the corresponding MFC.

Compliant with international standard method ISO6145-7 “Gas analysis -- Preparation of calibration gas mixtures using dynamic volumetric methods”  every instrument undergoes a rigorous factory calibration. Following highest metrology requirements, the instrument not only accurately prepares the gas mixtures, but it also automatically calculates and reports maximum relative uncertainty for every delivered concentration. The Audit Trail function performs complete traceability of the operations carried out.

Proven by thousands users worldwide the GasMix™ is well suited for:

• Calibration of GC, µGC, gas analysers
• Calibration, repeatability, and linearity checks of environmental AMS
• Validation, model building and calibration of FTIR, RAMAN and other spectrometers
• Preparation of customised secondary standards for calibration laboratories and inspections
• Generation of complex on-demand gas mixtures for specific research applications
