Fluorolog-QM

Modular Research Fluorometer for Lifetime and Steady State Measurements

The HORIBA Fluorolog-QM™ series of modular research grade spectrofluorometers is the fourth generation of the world famous HORIBA Fluorolog, with the first Fluorolog introduced by Spex Industries in 1975.

The Fluorolog-QM represents the culmination of decades of HORIBA’s industry-leading experience in development and manufacture of the highest level of spectrofluorometer performance and versatility. The Fluorolog-QM, with its exquisite, optically perfect, all reflective optics, combined with a multitude of light source and detector options, and sample handling accessories, provides the highest sensitivity and greatest versatility of any spectrofluorometer.

The Fluorolog-QM can be enhanced to suit a broad array of luminescence experiments, with the industry’s most extensive list of optional accessories to expand capabilities and performance, to meet all of the most demanding research lab’s experimental needs. And when you purchase a Fluorolog-QM all of these enhancements and accessories can be added to your system at any later time as your needs change, or funds become available.

With thousands operating in universities and research labs around the world, and tens of thousands of publications, Fluorolog has proved itself to be the best choice for the most demanding steady state, time-resolved, TCSPC, PLQY and NIR research.

                  PLQY in NIR with Fluorolog-QM and K-Sphere
                  PLQY in NIR with Fluorolog-QM and K-Sphere
                  The Fluorolog-QM fluorescence spectrometer with an integrating sphere option is an excellent choice for PLQY measurements in NIR. The K-Sphere is very convenient and easy to use, as it couples directly to the sample compartment optics and allows a use of external light sources, such as DPSS lasers, which can be attached to the front of the sample compartment. The sphere has holders for cuvettes, slides and powders that can be easily interchanged. The results demonstrate very good reproducibility and precision for NIR PLQY measurements spanning almost two orders of magnitude. Based on multiple measurements, the demonstrated PLQY standard deviations range from 1.3% for high QY value (77%) to 6.4% for the QY below 1%.

                  Fluorescence on Small or Solid Samples
                  Fluorescence on Small or Solid Samples
                  Samples can be valuable. Either you don’t want to waste them, or you may not have very much starting material. Biological proteins and enzymes, for example, are often obtained in small volumes and may be expensive.
                  Recording Fluorescence Quantum Yields
                  Recording Fluorescence Quantum Yields
                  When a fluorophore absorbs a photon of light, an energetically excited state is formed. The fate of this species is varied, depending upon the exact nature of the fluorophore and its surroundings, but the end result is deactivation (loss of energy) and return to the ground state.

                  Photoluminescence Spectroscopy of Quantum Dots
                  Quantum dots (QDs) have potential applications in optoelectronics, biosensing, biolabeling, memory devices, and sources of laser light.
