How to Choose the Right Gas Mixer for Your Laboratory: 7 Specs That Actually Matter The right gas mixer is the one whose specifications match how your lab actually works. Seven specs decide it: the dilution ratio you need, how many gases you blend at once, your required concentration accuracy, the traceability and uncertainty you […]

Do You Really Need a Gas Mixer? When One Cylinder Isn’t Enough By Laurent & Klaudia, AlyTech The short answer You need a gas mixer or gas diluter when a single certified cylinder cannot cover your whole analytical range — and a dynamic dilution system lets you keep one concentrated certified cylinder and generate every

In short: EPA Method TO-17 measures VOCs collected by active sampling on sorbent tubes and analysed by thermal desorption (TD) GC–MS. Reliable quantification depends on calibration standards loaded onto the tube in the gas phase, the same physical state as the field sample. GasMix and LiqMix dynamic dilution systems generate these matrix-matched, multipoint standards on

NEPHOS by LiqMix: BTEX & VOC Gas Standards Generated from a Single Liquid NEPHOS is a liquid-to-gas standard generator that produces traceable BTEX and VOC calibration standards on demand from one liquid reference, replacing a shelf of certified cylinders. It vaporises a liquid standard into a controlled gas stream, reaches concentrations from percent down to

NEW PRODUCT  ·  MAY 2026 Alytech Launches ZEPHYR II: The Next Generation Smart Gas Diluter from GasMix™ Alytech is proud to announce the launch of ZEPHYR II, the next generation of the GasMix™ smart gas diluter with two channels. ZEPHYR II is the first ZEPHYR to run AlySoft, the unified software platform behind every GasMix™

How Modern Gas Mixers Achieve Reliable, Defensible Accuracy A gas mixture is only as good as your ability to prove it. Modern mass flow controllers are excellent, but hardware alone does not make a result defensible. What does is the system around it: bidirectional MFC control that reads back actual delivered flow in real time,

Why MFC Flexibility is Redefining Modern Metrology 1. Fundamental Operating Principles: Stability vs. Agility The Sonic Nozzle (Fixed Geometry): This technology generates mass flow by accelerating gas to the speed of sound at a fixed orifice (choked flow). While mechanically elegant, it is inherently discrete; flow is locked into fixed hardware steps, requiring physical manifold

NIST Traceable Certified Value: What It Means and Why It Matters for Gas Calibration If you work in gas analysis, environmental monitoring, or laboratory calibration, you have likely encountered the term NIST traceable certified value. But what does it actually mean — and why does it matter for the accuracy and legal defensibility of your measurements?

Hydrogen Fuel Purity Calibration (ISO 14687) How to calibrate hydrogen impurity analysers at trace levels, on demand and traceably. ISO 14687 sets impurity limits for fuel-cell hydrogen down to the ppb range, where the calibration standard, not the analyser, becomes the hard part. Commercial trace-level cylinders are expensive, slow to deliver, short-lived and carry 10 to 20 %

Trace-Level Gas Generation: Trustable Calibration at ppb Concentrations At sub-ppm and ppb levels, the limit on measurement quality is no longer the analyser, it is the calibration standard. Dynamic gas dilution under ISO 6145-7 generates traceable trace-level standards on demand: high-accuracy mass flow controllers with a combined uncertainty below ±1 % of set flow, dilution down to
