Thermo Fisher Scientific To Launch New Fluorescence Spectrometer

Designed for both demanding research applications and routine laboratory analysis, the Lumina delivers 0.5nm spectral bandwidth, high sensitivity and fast scanning speed, providing performance for assay development, quantification and sample analysis applications in life science, QA/QC, materials science, pharmaceutical, environmental, photochemistry and luminescence laboratories.

Thermo Fisher will showcase the fluorescence spectrometer at the Biophysical Society 54th Annual Meeting, being held February 20-24 in San Francisco.

Thermo Fisher claimed that with its ability to provide 0.5nm 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.

The 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 monochromator drive mechanism enables slewing at 20,000nm/min and wavelength scanning at speeds of up to 6,000nm/min. This reduces the exposure of photosensitive samples during synchronous and 3D scanning experiments.

The instrument’s photomultiplier detector offers extended measurement of the near-infrared wavelength (190nm to 900nm), 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.

Michael Allen, product manager of UV-visible and fluorescence products at Thermo Fisher Scientific, said: “With the launch of the Thermo Scientific Lumina, our customers can now achieve advanced spectral resolution for both excitation and emission spectra. 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.”
