New Combined CO2/O2 In-situ Gas Analyser

New compact gas analysers for the parallel measurement of CO2 and O2 have been introduced recently by BlueSens (Germany). The BlueInOne series is currently comprised of two different models, the BlueInOne Ferm and the BlueInOne Cell.

The BlueInOne Ferm is designed to analyse fermentation processes, while the BlueInOne Cells is primarily designed for studying cell growth processes. The analysers are, of course, also suitable for other real-time gas analysis applications.

The BlueInOne is quick and easy to integrate into processes, providing readings with a high level of reliability. The measuring signals can be exported as analogue signals (4-20 mA each for both signals) as well as digital signals (RS485 Modbus, RS232, USB). Data can be logged during measurement using an optional web server, and is very easy to display when needed in any up-to-date browser via a network connection. BlueInOne is suitable for integration into any production level in Bioprocessing and can detect the carbon dioxide and oxygen content there in real time.

Each compact analyser unit reacts automatically to changing conditions. Fluctuations in moisture and pressure are identified and compensated automatically. This ensures the measurements remain precise even under changing process conditions.

BlueInOne features a resolution of up to 50 ppm and is suitable as a replacement for cost-intensive mass spectrometers. Standard interfaces such as Modbus or USB allow it to be connected to any process control system or a PC. Sampling becomes superfluous while automatic and consistent monitoring and documentation of bioprocesses is made possible.
