Press Release Summary:
ReactRA(TM) 4000 Reaction Analyzer utilizes Raman, a complementary technique to FTIR for tracking chemical reaction components. Since signals from solids in suspensions or slurries can also be measured using Raman, crystallizations can be monitored in situ. Information can be directly related to Lasentec FBRM(TM) and PVM(TM) data on particle size, shape, and events. ReactRA 4000 uses integrated 785 nm laser transmitted to sample via fiber optic probe.
Original Press Release:
Reactra(TM) 4000 Raman Reaction Analyzer
METTLER TOLEDO AutoChem recently introduced the ReactRA 4000 Raman Reaction Analyzer for in situ monitoring of chemical reaction species. Raman is a complementary technique to FTIR for tracking reaction components in real time as certain chemical bonds will be more readily observed using Raman, for example -C=C- bonds in polymerizations. Signals from solids in suspensions or slurries can also be measured using Raman, therefore crystallizations and in particular polymorph and solvate formation can be monitored in situ using the ReactRA 4000. This information can be directly related to Lasentec FBRM(TM) and PVM(TM) data on particle size, shape, and events.
The ReactRA 4000 uses an integrated 785 nm laser that is transmitted to the sample via a fiber optic probe. When the laser hits the sample some of the scattered light will have frequencies that relate to the way that the molecule vibrates. This light is collected and sent through a high resolution, high throughput echelle spectrometer where it is dispersed and collected on a Peltier cooled CCD (charge coupled device) detector. These signals are generally very sharp and chemically specific and thus can be directly related to reaction components including starting materials, intermediates, products, and by-products.
A significant advantage of the ReactRA 4000 is the use of fiber optic probes for sampling.
These probes are made of chemically robust hastelloy and sapphire and are compatible with all METTLER TOLEDO RCle(TM), LabMax®, and MultiMax(TM) vessels as well as standard glassware and pressure vessels. The standard length of the fiber optics is 5 to 100 meters to allow for easy interfacing. Also the ReactRA 4000 does not need any dedicated facilities such as liquid nitrogen or purge and therefore can be conveniently moved from lab to lab or even the pilot plant.
The software for the ReactRA 4000 system has all of the built-in tools and algorithms for real time reaction analysis. Collection, component profiling, quantitative analysis, and our improved ConcIRT(TM) algorithm which has made analyzing complex reaction data easy, are all in one package.
