The latest version of Renishaw’s Virsa™ Raman analyser, with new WiRE™ 5.5 software, enables users to analyse samples using remote fibre-optic probes. The new system has LiveTrack™ focus-tracking technology and the new Monitor™ software module. These enable it to perform real-time analysis on large samples that have irregular surfaces, are changing shape as they undergo phase changes or that move, such as those on production lines. The Versa has a modest footprint and can be used on a bench or mounted in an industry-standard 19" rack.
The Monitor software module allows the processing and analysis of a constant flow of Raman data, enabling changing chemical concentrations or other sample properties to be monitored. It is applicable to many applications and ideal for users who are looking to understand and monitor processes in development or production stages, as well as scientists looking to track spectral changes as their experiments progress. The Monitor software module can be applied to a wide range of sampling situations including: sampling liquids with immersion probes; examining, via a window, materials in containers, vessels or reactors; and analysing the surface of a material in conjunction with Renishaw’s LiveTrack focus-tracking technology.
Also new is the PLS analysis module, which has industrial and academic applications, especially in fields such as pharmaceuticals. It is now available as part of the WiRE 5.5 software. You can generate and test PLS models, and then predict values in real time (when used with the Monitor software module). Values can be predicted for any material which exhibits a spectral change, for example concentration or crystallinity changes.
