In this work, we demonstrate our activities towards the combination of an ultrasound (US) enhanced ATR-IR setup for analysis of bacteria in water. For samples containing low bacteria levels, US-enhanced ATR-IR spectroscopy poses an interesting approach, because the standing ultrasonic wave (USW) can be used in a first step for accumulation of the bacteria in the sample cell. Subsequently, the enriched bacteria solution is forced towards the ATR element for interaction with the evanescent wave.
