fluorometer

 [floo͡-rom´ĕ-ter]
the instrument used in fluorometry, consisting of an energy source (e.g., a mercury arc lamp or xenon lamp) to induce fluorescence, filters or monochromators for selection of the wavelength, and a detector.

fluor·om·e·ter

(flōr-om'ĕ-tĕr),
A device employing an ultraviolet source, monochromators for selection of wavelength, and a detector of visible light; used in fluorometry.

fluorometer

(1) An instrument used to measure the intensity and wavelength distribution of fluorescent emissions after excitation by a certain spectrum of light.
(2) A now-retired device formerly used to measure the amount of ionising radiation emanating from an X-ray tube.

fluor·om·e·ter

(flōr-om'ĕ-tĕr)
A device employing an ultraviolet source, monochromators for selection of wavelength, and a detector of visible light; used in fluorometry.

Using a 3-mm punch from an identical DBS and the previous fluorometric LAL assay with and without Lalistat-2 (5), we obtained a specific activity of 466 [micro]mol/h/L (within the range of values reported previously) for the LAL component, which is 1.9-fold lower than the activity measured with the new UPLC-MS/MS assay.
