Method and system for real time in-situ monitoring of a solution during a solution based process

摘要

The invention concerns a method and system for real time in situ monitoring of a solution during a solution based process, a reference sample (6) being immersed in the solution, the method comprising the following steps:- Emitting an excitation light in the solution and on the reference sample (6);- Collecting a Raman spectrum generated by the solution and by the reference sample (6);- Comparing the Raman spectrum generated by the solution with the Raman spectrum generated by the reference sample (6).;The system comprises a Raman probe (4) comprising an emission source (1) and a photodetector unit (2). Preferably the excitation light is guided to the solution and the reference sample (6) via an optical fiber (3). Preferably the Raman scattered light is guided to the photodetector unit (2) via an optical fiber (3).
