Raman spectroscopy is especially useful for reaction monitoring, product identification, remote sensing, and the characterisation of highly scattering particulate matter in aqueous solutions. Based on the principle discovered by Prof. Chandrasekhara Venkata Raman, it measures the result of the inelastic scattering of photons.

​

The AvaSpec-HERO is integrated into the AvaRaman system. Because of the low dark noise of the HERO (only 2 counts), you’ll have great performance. The superior signal-to-noise ratio (800:1) is important when you’re dealing with small signals, which is typically the case in Raman. Also, when small process changes need to be monitored in time, the HERO is superior as the small change process will lead to a small change in signal which can be discriminated by the excellent SN ratio. The high NA optical bench also results in a better sensitivity - this will lead to more photons impinging on the detector.

 

Temperature control is critical in Raman measurements to create stable results over time. Cooling to -10 °C for the lowest noise performance and very stable cooling control ( +-0.1 °C accuracy) delivers accurate and reproducible results. This provides you with a combination that is suitable for the more demanding applications (low light, better signal-to-noise, low noise ratio).

​

The AvaRaman system is equipped with a cooling system, cooling the detector down to -35°C cooling versus ambient, reducing noise by a factor of 2-3, enabling the use of longer integration times to enhance the detection of small signals.

 

The AvaRaman system is delivered with special AvaSoft-Raman software, with Panorama-Pro software also being available for Raman interpretation and functional group assignment.

​

A selection of different probes is also available to allow selection of the most appropriate one for your application.
