THz-Raman® Well-Plate System (WPS)

Coherent’s new TR-WPS Automated Well-plate Measurement System combines high throughput screening (HTS) capability with our patented low-frequency/THz-Raman® technology to automatically capture the entire Raman spectrum from -800 cm-1 to +2800 cm-1 for common well-plate measurements. Ideal for screening and identification of polymorphic compounds and co-crystals, or quantifying degree of crystallinity in pharmaceuticals, THz-Raman delivers fast, sensitive, and reliable measurements of both chemical composition and molecular structure. The relative ease of sample handling and measurement ensures that the user spends more time with the data, rather than collecting it.

The TR-WPS has been designed to be fully automated, from sample insertion to data generation. The sample is excited with a 785 nm Coherent CleanLine™ laser from below the well in an inverted microscope format. A plate autofocusing system ensures measurement repeatability, and an integrated vision system with polarized light detection can be used to determine areas of interest within each well.

The WPSTM Application Software Interface has a highly intuitive GUI with a layered design, enabling fast learning and simplified operation, while providing extensive additional functionality in advanced mode.
