Enabling Robust and Rapid Raw Material Identification and Release by Handheld Raman Spectroscopy

Area of Science:

• Analytical Chemistry
• Spectroscopy
• Pharmaceutical Manufacturing

Background:

• Current pharmaceutical raw material identification relies on time-consuming compendia methods.
• Existing methods often involve subjective spectral comparisons and extensive sample preparation.
• A need exists for rapid, non-destructive, and objective raw material identification in warehouse settings.

Purpose of the Study:

• To develop and validate a rapid, objective, and non-destructive method for raw material identification.
• To implement Raman spectroscopy for real-time identification of raw materials upon receipt.
• To support biopharmaceutical cell culture processes with enhanced raw material quality control.

Main Methods:

• Developed and validated a rapid identity (Rapid ID) method using a Bruker BRAVO handheld Raman spectrometer.
• Created a library of reference spectra for 46 common raw materials used in biopharmaceutical processes.
• Evaluated method repeatability, reproducibility, selectivity, and robustness against operational factors.

Main Results:

• The Rapid ID method significantly reduces raw material quality release time from weeks to minutes.
• Achieved objective identification with enhanced data integrity through autonomous electronic reporting.
• Demonstrated robustness against instrumental variance, packaging, and thermal effects.

Conclusions:

• Handheld Raman spectroscopy offers a fast, reproducible, and non-destructive solution for raw material identification.
• The Rapid ID method aligns with Pharma 4.0 principles, enabling automated processes and continuous verification.
• The approach enhances objectivity, data integrity, and supports continuous improvement initiatives.
