Case Study: Detection of VOC gases and CO2 by active sample delivery via micropump

posted in: Case study | 0

Sensing ambient gas phase compositions is a crucial task in today’s everyday life. Be it for containing stable conditions or for supervising potential toxic concentrations, in many circumstances gas phase analysis has become a powerful tool.

When analysing cell growth, it is essential to observe carbon dioxide levels. Additionally, when ambient pollution has to be measured, volatile organic compound (VOC) sensors are used.

In the following experiment, it will be shown how via the mp6 micropump by Bartels Mikrotechnik GmbH it has become possible to transport gas phases in microliter proportions to such sensors. It is of great importance to understand whether and how the procedure is functioning. Thus, the gas phase biological experiment within a closed reservoir will be analysed.

For quantitative results, the gas will be conveyed to a VOC and a CO2 sensor at different fermentation stages and the development of both concentrations is going to be displayed and analysed.
