Event Overview:
Transmission Raman Spectroscopy (TRS) is licensed in the pharmaceutical industry for the identification and determination of bulk assay and uniformity of content of finished products. The first part of this webcast will cover the basic principles of Raman spectroscopy, discussing the advantages and limitations over conventional testing methods, the process steps required to select suitable products for Raman testing, and the development and validation requirements of Raman methods and models. This presentation will also review regulatory submissions of Raman methods and the lifecycle maintenance of licensed Raman models. The second part of this webcast will describe how LDIR technology can enable rapid, high-quality surface imaging of large tablet surfaces, for applications including polymorph screening in the formulation.
Key Learning Objectives:
- Advantages and limitations of Raman Spectroscopy over conventional methods for content uniformity testing
- Development of Raman models for bulk assay and UoC testing
- Rapid, high quality surface imaging of large tablet surfaces, for applications including polymorph screening in formulation development using LDIR technology

This column shows that a Raman plate reader paired with partial least squares regression can simultaneously quantify glucose, fructose, sucrose, and ethanol in yeast fermentation samples, using turbidity-matched calibration standards to correct for yeast-induced turbidity, and offers a rapid, label-free, high-throughput method for tracking sugar consumption and ethanol production in strain screening, media optimization, and process development.
This column, the second installment on highly substituted benzene rings, shows that tri- and tetra-substituted substitution patterns can be distinguished by whether the ring bending peak is present and by the position of the in-phase aryl C-H wagging peak, which shifts according to how many adjacent hydrogens the ring carries.
