A new look at an old classic: implementation of a SERS-based water hardness titration

Abstract

The principle of complexometric titration is here revisited in SERS on the case of water hardness determination. The SERS signal abruptly switches about the equivalence, enabling quantitative SERS analysis without the need for tedious calibration.
