Here, we report on a proof-of-concept study highlighting a new approach for quantitative surface enhanced Raman spectroscopy (SERS) measurements. This has been achieved by implementing the standard addition method (SAM) within a lab-on-a-chip (LOC) system. The approach has been successfully tested to quantify congo red as a model analyte even in the presence of the chemically related mole- cule methyl red. Thus, the developed concept demonstrates its potential to quantify analytes via SERS in the presence of other SERS active molecules.
