  • METHOD FOR RAPID IN SITU DETECTION OF AMMONIA
    Publication number: 20230184731
    Abstract: A method for detecting and quantifying an amount of ammonia in a sample by surface-enhanced Raman spectroscopy includes a step of position a liquid or gaseous sample proximate to a detection substrate. Incident light is focused onto the detection substrate while it is positioned proximate to the sample, the incident light having an excitation wavelength from about 500 nm to 800 nm. Raman activity from ammonia proximate to the detection substrate is then detected.
