High Throughput Virtual Slit (HTVS™) Impact on Raman Spectroscopy Limit of Detection (LoD) Performance

Conventional Raman systems have traditionally been limited by a lack of sensitivity due to the design trade-off between resolution and throughput mediated by the input slit of the spectrometer. Tornado’s proprietary high throughput virtual slit (HTVS™) design technique eliminates the spectrometer and associated slit losses while maintaining high spectral resolution, resulting in an order of magnitude improvement in sensitivity. This application note demonstrates the improved detection limits and corresponding minimum required acquisition times of four binary mixtures using Tornado’s HyperFlux™ PRO Plus Raman spectroscopy system. Higher sensitivity is achieved by using HTVS to eliminate the conventional trade-off between spectral resolution and optical throughput.
