A generic purpose, compact and affordable instrument for the chemical analysis of liquid samples based on the non dispersive infrared (NDIR) scheme is presented. It comprises a detector module built from two matching arrays of CMOS compatible thermopiles and non-specific infrared filters (Fabry-Perot resonators). Each filter provides a set of transmission peaks distributed along the mid-infrared spectral range instead of a single transmission peak associated to a specific wavelength, so that each channel collects information...
