(Thermo Fisher Scientific Inc.: Waltham, MA) -- Thermo Fisher Scientific Inc., a leader in serving science, has launched the Thermo Scientific Lumina, a new research-grade dual-monochromator-scanning fluorescence spectrometer that offers a new level of clarity in fluorescence measurement. Designed for demanding research applications and routine laboratory analysis, the Lumina delivers 0.5 nm spectral bandwidth, high sensitivity, and fast scanning speed, providing industry-leading performance for rapid and accurate assay development, quantification, and sample analysis applications in life science, QA/QC, materials science, pharmaceutical, environmental, photochemistry, and luminescence laboratories.

With its ability to provide 0.5 nm spectral bandwidth, the Lumina offers superior resolving power when compared with competitive systems in the same price range, enabling analysts to uncover the most detailed information about their samples, including sample features that are closely positioned, and better discriminate between peaks in spectra. Additionally, the Lumina’s increased sensitivity offers the advantages of lower limits of detection, less noise, and more consistent baseline measurements.

“With the launch of the Thermo Scientific Lumina, our customers can now achieve advanced spectral resolution for both excitation and emission spectra,” says Michael Allen, Thermo Fisher Scientific product manager for UV-visible and fluorescence products. “The combination of the instrument’s high resolution and increased sensitivity offers a new level of clarity to fluorescence spectroscopy, helping researchers dig deeper into their samples and unlock new information.”

The powerful xenon lamp in the Lumina, combined with optimized monochromators, allows for the detection of sample concentrations below parts-per-billion levels for compounds such as harmful heavy metals, polycyclic aromatic hydrocarbons, and more. A fast, accurate, and reliable monochromator drive mechanism enables slewing at 20,000 nm/min and wavelength scanning at speeds of up to 6,000 nm/min. This reduces the exposure of photosensitive samples during synchronous and 3-D scanning experiments. The instrument’s photomultiplier detector offers extended measurement of the near-infrared wavelength (190 nm to 900 nm), which facilitates cutting-edge research in biochemistry and photosynthesis applications.

With a large sample compartment and a wide range of accessories for temperature control, polarization, and solid sample measurement, the Lumina can be expanded for use in a variety of applications. The instrument uses Thermo Scientific Luminous software for complete instrument and accessory control, as well as efficient data collection, analysis, and reporting.
