Abstract: 
In this paper we report the development of a multi-parameter low-cost (< 100 EUR) portable Centrifugal Microfluidic Analysis System (CMAS) for the in-situ colorimetric analysis of nutrients. Microfluidic discs consisting of three PMMA (Poly(methyl methacrylate)) layers bonded together by two PSA (Pressure Sensitive Adhesive) layers were prepared. A 3D-printed housing was produced for hosting the microfluidic discs which incorporated a low-cost optical sensor for colorimetric detection and a motor which generated the centrifugal force necessary to carry out the tests. Limits of detections of 0.233 ppm, 0.189 ppm and 0.050 ppm were obtained for ammonia, orthophosphate and nitrite respectively.
