    Abstract: A hand-held microfluidic testing device is provided that includes a housing having a cartridge receiving port and a cartridge for input to the cartridge receiving port. An optical detection system in the housing is capable of providing an illuminated electric field useful for Raman spectroscopy. The cartridge may have a sample well. The sample well is loaded with a mixture of water containing the analyte, Raman-scattering nanoparticles and a calibration solution. The calibration solution contains an analogue of the analyte differing in its Raman response, for example an isotope of the analyte. Optionally, a chemical compound capable of increasing interaction between the analyte and the nanoparticles may be added.

    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.
