Flow Injection Analysis cell for electrochemical experiments

Batch Injection Analysis: a smart alternative

As an alternative to FIA systems, we have developed the Batch Injection Analysis (BIA) system, a robust and smart technique that eliminates some of the drawbacks associated with Flow Injection Analysis systems, such as air bubbles or leaking.

How does Batch Injection Analysis work? The BIA system uses a programmable electronic micropipette dispensing successive drops at reproducible flow rates and injection volumes. The solution is dispensed close to the working electrode surface. As the flow rate is highly controlled, the resulting peaks are as sharp as the ones obtained with FIA systems. Batch Injection Analysis systems are an easy way to obtain successive measurements in tubeless systems.
