Thermo Fisher Scientific Introduces New UV-Vis and Fluorescence Instruments at Pittcon 2010

Thermo Fisher Scientific Inc. introduces the Thermo Scientific Evolution Array UV-Visible (UV-Vis) spectrophotometer and the Thermo Scientific Lumina fluorescence spectrometer. The Evolution Array uses advanced photodiode array (PDA) technology to provide significant advantages in full-spectrum data acquisition and sample throughput when compared to traditional dispersive, monochromator-based spectrophotometers.

Full spectrum data is acquired at less than one second for routine data applications and can be acquired at nearly 50 points per second for advanced kinetics applications. The Evolution Array delivers industry-leading performance for rapid and accurate method development and sample analysis in QA/QC, materials science and educational laboratories.

The Evolution Array provides simultaneous detection of all wavelengths throughout the ultraviolet and visible regions of the spectrum, allowing a nearly instantaneous display of a full absorbance spectrum from 190-1100 nm. Full-spectrum analysis of every standard and sample allows users to create standard curves, plot 3D graphical displays and examine samples at any wavelength at any time. This significantly accelerates analytical method development.

The new Thermo Scientific Lumina fluorescence spectrometer offers twice the resolution power of competitive instruments. It provides a 0.5 nm spectral resolution, helping analysts isolate detailed information about samples. The instrument’s high resolution capability enables researchers to resolve sample features that are closely positioned and better discriminate between peaks in spectra. Additionally, its increased sensitivity offers lower detection limits, less noise and more consistent baseline measurements, delivering a new level of clarity in fluorescence measurement for QA/QC, materials science, environmental, photochemistry and luminescence laboratories.

The Lumina features a powerful xenon lamp and fast scan speeds (up to 6,000 nm/min), providing research-quality results for demanding samples. It can detect sample concentrations below parts-per-billion for compounds such as harmful heavy metals and polycyclic aromatic hydrocarbons. Additionally, the photomultiplier detector in the Lumina offers an extended measuring near-infrared wavelength (190 nm to 900 nm), which facilitates cutting-edge research in biochemistry and photosynthesis applications.
