Instrument: Fluorometer
A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. The instrument is designed to measure the amount of stimulated electromagnetic radiation produced by pulses of electromagnetic radiation emitted into a water sample or in situ.
Samples were analysed underway using a Turner Trilogy fluorometer (model #7200-000) with Turner UV fluorescence module (7200-041). Limit of detection was typically ~0.01uM NH4.
