Using 1064 nm Dispersive Raman Systems For Analysis Of Petroleum Products
6/18/2019
Raman spectroscopy is a non-invasive, highly sensitive technology that quantitatively probes and analyzes chemical compositions and structures without the need for sample preparation. In the past, this technology was not useful for petroleum and petroleum-based products due to their high levels of high level of photoluminescence that can overwhelm Raman signals in all visible wavelengths. This issue is now resolved by BaySpec’s line of 1064 nm excitation dispersive Raman systems that offer maximum reduction in fluorescence interference.

How To Make A Tissue Raman Measurement At 1064 nm
6/18/2019
The combination of improved Raman technology and the technique’s molecular sensitivity have led to a rise in Raman usage for a variety of applications including pharmaceutical, biomedical, industrial, and forensics. There remains, however, a struggle to extract useful Raman spectra from fluorescent and luminescent samples. For those users who require longer wavelengths such as 1064 nm, the only available option has been FT-Raman. Now, BaySpec’s new dispersive 1064 nm Raman spectrometers offer users a turn-key solution that combines the speed, sensitivity, and rugged design of traditional dispersive Raman instruments with the fluorescence avoidance of traditional FT-Raman instruments.
