UV-Visible spectrophotometer ThermoFisher Evolution 220
The UV-Visible (UV/VIS) spectrophotometer measures absorption of light in 190-1100 nm range. Measurements are possible in either ex-situ mode in cuvettes or in-situ using an external probe. The instrument is mostly used for the determination of elemental concentrations (e.g., Fe2+, As, Si, P) using well-established colorimetric methods. In addition, the spectrophotometer can also be used for the in situ and real-time monitoring of the nucleation, crystallization and growth of minerals, and is equipped with Single Cell Peltier System for temperature control and sample stirring.
