Abstract
In a method of measuring the amount of metaldehyde in water, a water sample of known volume is mixed with an isotopologue, a colorimetric dye and Raman-scattering nanoparticles. The water sample contains an analyte, for example metaldehyde. Optionally, the analyte may be treated to form a compound reactive with the dye. The amount of the analyte is measured by producing a Raman spectrum of the mixture and performing a ratiometric analysis of the Raman spectrum to quantify the analyte.
