Abstract
An analyte in water is quantified by mixing an internal standard with a water sample. The sample is analyzed with a Raman spectrometer. The analysis includes mapping the signal from the Raman spectrometer to the quantity of said analyte. The mapping can include using a calibration curve, for example a multivariate calibration curve, that was previously prepared with the internal standard. In other examples, a sample is measured after addition of a known amount of the analyte.
