Rapid scan near-infrared spectroscopy

To investigate the kinetics that control the rate of network connection of a highly cross-linked photopolymer system, Lovell et al. (2001) utilized rapid scan near-infrared (NIR) spectroscopy to study the polymerization of a dimethylacrylate dental resin. The research exploited the Thermo Electron rapid-scan capabilities to analyze the system with a time resolution of ss 30 ms. This was sufficiently faster than traditional techniques, which required data collection at the 2-second time scale and would thus miss the reaction of interest that reacts to... 

Rapid-scanning spectroscopy (RSS) is a method in which a selected portion of the ultraviolet, visible, or near-infrared spectrum is scanned on a time scale ranging from several sec to a few /isec. The applications of this technique to systems in which short-lived transient species exist or large reaction rates are encountered are numerous... 

Sierra et al. in 2007 conducted a study for the rapid prediction of the fatty acid (FA) profile of ground using near infrared transmittance spectroscopy (MT). The samples were scanned in transmittance mode from 850 to 1050 nm. MT spectra were able to accurately predict saturated R2=0,837, branched R2=0,701 and monounsaturated R2=0,852 FAs. Results were considered interesting because intramuscular fat content and composition influence consumer selection of meat products.
