The Ins and Outs of On-line Process Control with Raman and FT-IR Spectroscopy

Using Raman and FT-IR spectroscopy for on-line monitoring of manufacturing processes offers advantages such as improved quality control, nondestructive analysis, and reduced costs. Jim Rydzak has more than 20 years of experience leading teams in applying on-line process control, in both the pharmaceutical and consumer goods industries. He recently talked to Spectroscopy about that work, including what they achieved and how they overcame challenges. read more

Raman Polarization Measurements: Keeping Track of the Instrumental Components’ Behavior

Controlling the orientation of the laser and Raman polarization relative to the sample orientation can provide a wealth of information. But it is easy to produce erroneous results, so you need to know what instrumental components affect the observed polarization effects and how the sample setup itself affects the Raman signal. read more

Developing Portable Raman Spectroscopy Methods for Identification of Raw Materials Used in Pharmaceutical Development and Manufacturing

Great care is required when developing Raman spectral libraries for raw material identification. Critical factors—such as instrument type, Raman capability, container type, container interference, background interference, and material variability— can potentially influence the identity of the material. read more
