BPC Core working principle

1. Gas is collected under a flow cell in a chamber filled with water. While the flow cell is in its sitting position, a magnet located at its end is in contact with a sensor below it.

2. Once a certain volume has been collected, the force of buyuoance makes the flow cell open and release the gas. The magnet at the tip of the flow cell then loses it contact with the sensor and a measurement point is detected. For each point, the ambient temperature and pressure is registered to  be used adjusting the gas volume to standard conditions.

Effortless operation, maximum convenience

It`s all automatic! This translates to reduced labour costs, eliminating the need for expert assistance, and no more jotting down results in Excel files or notebooks. A user-friendly, intuitive interface simplifies the setup and monitoring of gas evolution or consumption processes. Whether it’s a research project or an industrial application, using BPC Core is a breeze. Just fill the measurement flow cells of BPC Core with deionized water, connect the unit to a power source, then start your experiment.
