Definition of fluorometer in US English:


(also fluorimeter)


  • An instrument for measuring the intensity of fluorescence, used chiefly in biochemical analysis.

    • ‘The fluorescence measured by the fluorimeter is the sum of autofluorescence from natural chromophores in the skin and PpIX fluorescence.’
    • ‘These instruments also have built-in fluorimeters that detect fluorescence emitted from nucleic probes annealed to target DNA at the conclusion of each PCR cycle.’
    • ‘The fumonisin was eluted with pure methanol and measured in a calibrated fluorometer.’
    • ‘The lamp intensity of the fluorometer was monitored for each sample.’
    • ‘The advantage that fluorescence imaging instruments have over conventional fluorometers is that images of fluorescence parameters can be obtained from whole leaves or large numbers of plants.’
