Thermo Fisher Scientific Unveils New UV-Vis Spectrophotometer

Thermo Fisher Scientific has launched a new UV-Visible (UV-Vis) spectrophotometer Evolution Array driven by photodiode array (PDA) technology that offers dramatic improvements in laboratory throughput.

Thermo Fisher claimed that the Scientific Evolution Array, designed for fast acquisition of full-spectrum UV-Vis data, delivers accurate method development and sample analysis in QA/QC, pharmaceutical, life science, materials science and educational laboratories.

By utilizing advanced photodiode array technology, the new instrument offers advantages with regards to full-spectrum data acquisition and sample throughput compared to traditional dispersive, monochromator-based spectrophotometers. Full spectrum data will be 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 array system provides simultaneous detection of all wavelengths throughout the UV 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 greatly enabling analytical method development.

The design of the Evolution Array enables longer uninterrupted operation, further increasing analytical speed. In addition, a complete line of accessories, including automated cell changers and temperature control and solid sample accessories, are available to facilitate system configuration according to specific laboratory requirements.

The Evolution Array operates on the Thermo Scientific VISIONcollect software to facilitate complete instrument and accessory control as well as efficient data collection, analysis and reporting. From routine quantitative analysis to 3D-spectrum kinetics, the software provides a spectrum radar visualization tool that allows users to view the entire active spectrum at a glance without interrupting work in the main display window.

Additional advanced software options are available for life science, film thickness and color applications. For regulated laboratories, the VISIONcollect software is designed to enable data handling in accordance with 21 CFR Part 11 requirements.
