Raman Analyzers
RAMANRXN3L MRA

The RAMANRXN3L™ Multi-Reactor Analyzer (MRA) is targeted to drug discovery and early process optimization customers. In these regimes, multiple parallel small-scale reactors (10-100 mL) are often used to monitor, analyze, and optimize the reaction chemistry. The ability to simultaneously follow several different potential reaction pathways can significantly speed up early process development and remove bottlenecks in the optimization pipeline. The multichannel RAMANRXN3L™ MRA meets and solves this need.

Raman spectroscopy provides the chemical specificity of mid-IR spectroscopy and the sampling simplicity of a near-IR analyzer. By operating in the visible spectral region, Raman spectroscopy allows vibrational spectra to be collected in situ, using fiber-coupled probe heads, without sample purging, and without the use of exotic sampling devices. The RAMANRXN3L™ MRA utilizes, as standard, fiber-coupled 1/4-inch OD probe optic technology for in situ reaction monitoring.

The RAMANRXN SYSTEMS™ suite of analyzers is based on advanced and innovative technologies that provide distinct advantages over traditional instrumentation. The HoloPlex™ advantage, standard in all RAMANRXN3L™ MRA systems, yields both full spectral coverage and high spectral resolution simultaneously for improved qualitative and quantitative analysis. Analysis is fast because the entire Raman spectrum is measured simultaneously, which translates into real-time data collection for reaction analysis and monitoring. The RAMANRXN3L™ MRA uses an optional Raman Calibration Accessory (HCA) and advanced calibration protocols, developed and demonstrated in the process arena, to ensure optimal instrument performance and calibration transferability.
