Thermo Fisher Scientific Unveils v4.1 VISION Software for UV-Visible Spectrophotometers

Thermo Fisher Scientific, the world leader in serving science, today announced the availability of the latest upgrade to its VISION software package for Thermo Scientific Evolution™ and Helios™ UV-Visible spectrophotometers.

Version 4.1 adds unique features to the already advanced VISIONsecurity™, VISIONlife™ and VISIONpro™ software, including the ability to remotely trigger the start of data collection and automatic readings via remote fiber optic probes. The new software provides extended capabilities for a wide range of applications in general QA/QC, materials science and life science markets.

Version 4.1 enables VISIONlife and VISIONpro software to instruct Thermo Scientific UV-Visible spectrophotometers to automatically start collecting kinetics data. This is particularly useful in the life science market where fast reactions need to be studied. The upgrade package enables the interface between the pneumatic drive of a rapid mixing accessory to mix reactants and trigger the spectrophotometer to start collecting the data remotely. When coupled with the Evolution 300, version 4.1 enables 50 data points to be collected in the first 1000 milliseconds of the reaction with a dead time of less than 8 milliseconds.

The new software also features remote fiber optic probe triggering to provide automatic readings remotely from the instrument, thus increasing time efficiency and providing greater sample throughput. This feature is of interest to researchers whose target vessel is located a short distance (<10 meters) away from the spectrophotometer. For example, a remote fiber optic probe could be used inside a drybox or controlled atmosphere environment. For added convenience, a built-in trigger switch located on the fiber optic probe is used to initiate readings. Remote fiber optic measurements can save considerable time compared to using traditional cuvettes and sipper systems.

VISION 4.1 continues to provide an industry-standard UV-Visible software platform under 21 CFR Part 11 Compliance. New capabilities in VISIONsecurity 4.1 provide additional audit trail events, event monitor functionality, and enhanced electronic signature monitoring for customers under this regulation. Additionally the integration into Microsoft^® operating system allows data to be protected even when the VISIONsecurity software is not running.

Additionally, the new built-in weight and volume correction feature saves valuable time by eliminating post run data calculations. New advanced baseline functions for 0%T baseline and standard reference correction enables customers to accurately obtain diffuse reflectance measurements. This, combined with new features for on-line Savitzky-Golay smoothing provides user flexibility to achieve the best possible diffuse reflectance data. VISION 4.1 can also be integrated with other software packages, for example Microsoft Excel and the Thermo Scientific GRAMS/AI™ 8.0 or OriginLab Corporation’s OriginPro 7.5 for further calculations.
