AS251: Real-Time Analysis of VOC Production From An Algae Bioreactor Using Select Ion Flow Tube Mass Spectrometry (SIFT-MS)

Algae can be cultivated in large bioreactors, using a range of technologies, for purposes as diverse as biomass production, water treatment and CO₂ fixation.

Algae biomass can be extracted or refined to produce compounds such as bioethanol or higher value products such as fatty acids and protein.

Careful monitoring of the health of the bioreactor can significantly increase yields, leading to a commensurate increase in income from harvested products.

The ability of Select Ion Flow Tube Mass Spectrometry – SIFT-MS – to measure gas phase volatile organic compounds (VOCs), in real-time, offers a unique approach to monitoring critical compounds produced by the bioreactor, potentially at low parts-per-billion by volume (ppbV) levels.

This Application Note demonstrates the ability of Select Ion Flow Tube Mass Spectrometry – SIFT-MS – on a pilot scale facility, over the course of several weeks and shows the utility of this approach in maximising outcomes.
