Spectroscopy and flow methodologies are an interesting and fruitful marriage in the field of Green Analytical Chemistry (GAC). Automation, immobilization of analyte, reagent(s), reaction product, or catalyst on active solid surfaces and miniaturization are highlighted as alternatives for waste decrease. Flow-Through Solid-Phase Spectroscopy (FSPS) can be envisaged as a variant of the use of immobilized reagents. It is implemented by placing the solid support inside the flow cell in order to perform the analyte (or its reaction product) retention and detection simultaneously. FSPS is an interesting spectroscopy approach that offers simple and rapid procedures that fulfil satisfactorily the requirements demanded by GAC. This article is focused on the contribution of FSPS methodologies to the GAC concept. The different strategies and types of FSPS developed will be presented and discussed in detail under the Green Spectroscopy point of view.
