2011 R&D 100 Winner
The Thermo Scientific Evolution 201/220/260 UV-Visible Spectrophotometers featuring INSIGHT and CUE Software were designed to satisfy specific applications, from standard quantitative analysis, to life science research and material science assays.
The instruments, from Thermo Fisher Scientific, Madison, Wis., use double-beam geometry with either 1 nm or variable spectral bandwidths. When a sample changes during the measurement period, a double-beam spectrophotometer delivers the most accurate data possible. Application focused beam geometry (AFGB) results in the best performance from microcells, fiber optic probes, and solid sampling. The Evolution 220 system uses AFBG options for solids and materials. The sharply focused small beam from AFBG allows 80% of light to pass through the 2- by 2-mm aperture of a 40-µL microcell.
The Customized User Environment (CUE) software employs flowchart-like tools to program multi-step analyses for future use. INSIGHT software offers users the ability to perform quantitative measurements using either fixed wavelength or scanning modes. A removable sample detector provides flexibility in the location of the sample measurement and the type of vessel or accessory used. Placement of the sample detector at the point of measurement assures the greatest possible energy throughput and best possible performance.
