Increased raw material verification capabilities with portable Raman and XRF instruments
ABOUT THIS WEBINAR
This webinar explored the use of the Thermo Scientific™ handheld Raman analyser TruScan™ RM with TruTools™ on-board chemometrics to verify the identity of challenging raw materials.
We discussed a portable XRF instrument, the Thermo Scientific IonicX™, and explained how it can identify ionic salts in seconds and replace traditional time-consuming and resource-intensive wet chemistry and benchtop methods.
In pharmaceutical manufacturing, handheld Raman analysers are widely accepted for material verification of excipients and APIs. For many years the pharmaceutical industry has used TruScan RM’s embedded multivariate residual analysis decision engine to identify most pharmaceutical raw materials directly. When characterising complex samples such as structural analogues, highly similar formulated materials or contaminated materials, building chemometric models to enhance specificity is necessary. As real-world examples, we will discuss the use of TruTools on-board chemometrics to discriminate:
- Various colours of Opadry solid dosage film coatings
- Different molecular weight polyethylene glycols (PEGs)
- Diethylene glycol (DEG) contaminated glycerol
- Structural analogues povidone and crospovidone
- Buffer solutions.
TruTools offers advanced pre-processing of spectral data, qualitative discrimination, quantitative component analysis, and customised 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 analyser 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 on the enhanced capabilities of portable instruments for raw material verification. A questions and answers session followed the presentation.
