Thermo Fisher Scientific Launches Research- Grade Fluorescence Spectrometer
Product News Feb 26, 2010
Thermo Fisher Scientific Inc. 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 both demanding research applications and routine laboratory analysis, the Lumina™ can deliver 0.5 nm 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 showcased the fluorescence spectrometer at the Biophysical Society 54th Annual Meeting, held February 20-24 in San Francisco.
Thermo Fisher Scientific claims that with its ability to provide 0.5 nm spectral bandwidth, the Lumina offers 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 sensitivity offers the advantages of lower limits of detection, less noise and more consistent baseline measurements, the Company said.
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 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 3D scanning experiments.
The instrument’s photomultiplier detector offers extended measurement of the near-infrared wavelength (190 nm to 900 nm), which facilitates 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.
