Increased raw material verification capabilities with portable Raman and XRF instruments

This webinar explored the use of the Thermo Scientific TruScan RM Handheld Raman Analyzer with TruTools on-board chemometrics to verify the identity of challenging raw materials.

In this webinar, Thermo Fisher Scientific discussed a portable XRF instrument, the Thermo Scientific IonicXPortable XRF Analyzer, and explained how it could identify ionic salts in a matter of seconds, replacing traditional time-consuming and resource-intensive wet chemistry and benchtop methods.

In pharmaceutical manufacturing, handheld Raman analyzers are widely accepted for material verification of excipients and APIs. For many years the pharmaceutical industry has used TruScan RM Handheld Analyzer's embedded multivariate residual analysis decision engine to identify most pharmaceutical raw materials directly.

When characterizing complex samples such as structural analogs, highly similar formulated materials, or contaminated materials, building chemometric models to enhance specificity is necessary. The webinar will use TruTools on-board chemometrics as real-world examples to discriminate:

  • Various colors of Opadry solid dosage film coatings
  • Different molecular weight polyethylene glycols (PEGs)
  • Diethylene glycol (DEG) contaminated glycerol
  • Structural analogs povidone and crospovidone
  • Buffer solutions

TruTools offers advanced pre-processing of spectral data, qualitative discrimination, quantitative component analysis, and customized chemometric models, including PLS, PCA, and PLS-DA.

Complementary to the use of Raman and NIR portable instruments for raw material ID is the new IonicX portable XRF analyzer for identity testing of pharmaceutical ionic salts. Built for biopharmaceutical manufacturing, IonicX is 21 CFR part 11 compliant and employs a patented algorithm C-value which allows ionic salts to be identified in seconds using portable X-Ray fluorescence.

Join Dr. Lin Chen, Thermo Scientific Application Scientist, and learn more about the enhanced capabilities of portable instruments for raw material verification. A questions and answers session followed the presentation.
