- •
A portable, low-cost and continuous sensing technology for profiling colonic gases from in-vitro fecal fermentation is proposed.
- •
The technology relies on anaerobic gas sensing in a regulated pressure incubation chamber, mimicking the colon environment.
- •
The performance of the system was evaluated using fecal samples of healthy humans.
- •
The effect of different gas mixtures in the headspace was investigated and the ideal mixture was defined.
