Dual-Channel Process Monitoring: Combining NIR and Raman Spectroscopy in a Single Probe

During active pharmaceutical ingredient (API) crystallization and drying, comprehensive process understanding demands simultaneous insight into chemical composition and solid-state structure. Operators routinely track two distinct parameters in real time: residual solvent or moisture content, and crystal polymorphism. Historically, monitoring both attributes in situ presented a practical instrumentation bottleneck. Near-infrared (NIR) spectroscopy excels at quantifying water […]
