Trilogy Laboratory Fluorometer

Fluorescence modules are available for chlorophyll a, (extractive acidification and non-acidification plus in vivo), rhodamine and fluorescein dye, cyanobacteria (phycocyanin and phycoerythrin pigments), CDOM, optical brighteners and ammonium. For extracted chlorophyll measurements using EPA 445, Trilogy automatically calculates the concentration using the filtered and solvent volumes. The Turbidity Module uses an IR LED with a wavelength of 860 nm to meet ISO 7027 requirements for Turbidity water quality measurements.

The Absorbance Module accepts interchangeable filter paddles so measurements can be made at different wavelengths in order to identify or place a sample in a particular class of compounds.

The standard filter paddle wavelengths/bandwidths are: 560/10; 600/10 and 750/10 nm.
