Abstract

A sensing system and method for sensing a component in a liquid is disclosed. The system comprises a microfluidic channel, the microfluidic channel comprising a first end and a second end, wherein the microfluidic channel is open at the first end and closed at the second end. The system also comprises at least one measurement sensor positioned adjacent the first end, the measurement sensor being arranged for detecting a measurement signal and a reference sensor positioned in the microfluidic channel adjacent the second end, the reference sensor being arranged for detecting a reference signal of the liquid. The system further is configured for combining the measurement signal and the reference signal so as to filter out background influences.
