ACUBLEND™ and FLEXBLEND™ Master Class
Scott Brand ACUBLEND Master Class mixtures are produced using our patented ACUBLEND and FLEXBLEND gas blending and analysis technologies. These unique processes allow Air Liquide to blend, mix, compress and analyze gas mixtures in a single operation using either gas or liquid phase minor components.
More calibration gas mixtures have been manufactured by ACUBLEND than any other process, making it a true standard for gas blending. Many customers have come to depend on the homogeneity, consistency and repeatability of ACUBLEND mixtures for their ongoing, close tolerance calibration needs. Because the ACUBLEND and FLEXBLEND processes are so tightly controlled, the cylinders produced from them are completely homogeneous from top to bottom within the cylinder, from cylinder-to-cylinder, and even from batch-to-batch. Each cylinder contains a mix that has a single-certified analytical concentration, accuracy and traceability when the blending is finished.
- Calibration for multiple users
- Auto emissions test cells
- Multi-facility calibrations
- Long-term or recurring calibrations
- Homogeneous consumable process materials
- Applications requiring large volumes of a given mixture
Dynamic Blending Using Proprietary Reference Standards
ACUBLEND Master Class mixtures are dynamically blended using high resolution, real-time analyzers. We use NIST or Air Liquide Reference Standards (ALRSs) for primary calibrations. Air Liquide employs extensive, proprietary calibration algorithms to control our analyzers and achieve an analytical accuracy of ±1% or ±2%, depending on the concentration range you choose.
Scott ACUBLEND Master Class mixtures are backed by our state-of-the-art process controls and include those mixtures where our knowledge of real-time sensors and calibration techniques has demonstrated that an interference-free measurement can be made in real time and within our analytical accuracy specifications. As with our other product classes, raw materials are carefully selected and verified to purity specifications prior to use in the ACUBLEND process.
Air Liquide provides a detailed Certificate of Accuracy with every ACUBLEND Master Class mixture. The analyzed concentration is reported for each minor component. In addition, the requested concentration can be shown.
ACUBLEND Master Class gas mixtures can be manufactured with our exclusive feature, Zero Blend Tolerance.
Why Is Zero Blend Tolerance Important?
Zero Blend Tolerance simply means "no deviation from ordered concentration," in that the concentration we produce for you is the same as the concentration you requested. Zero Blend Tolerance is a very useful feature for those applications where you need a calibration standard at an exact, specified concentration, or where a new calibration standard that you order must match up exactly with your existing ACUBLEND Master Class mix currently in use. Repeat orders can perfectly duplicate prior orders and cylinders can be interchanged with no harm to your process.
