How HPLC-CAD Analysis Can Allow You to See Hidden Extractable Oligomers

Join us for an informative webinar where we'll unveil our innovative in-house method for studying Extractables and Leachables (E&L) substances in common medical and pharmaceutical-grade plastics.

We'll dive into the analysis of nylon, polyurethane, and PVC (epoxidized soybean oil) oligomers, showcasing our approach that leverages multiple advanced detectors to analyze a wide range of analytes with diverse chemical properties.

Our method incorporates an ingenious inverse gradient technique, fine-tuned with an in-line mixer and optimized gradient delay times. We'll demonstrate the application of a previously published calculation to determine analyte behavior, classifying them as non-volatiles or semi-volatiles using CAD (Charged Aerosol Detection).

By attending, you'll discover how our approach minimizes inter-analyte response factor variation, enhancing quantitative accuracy and reducing uncertainty in setting analytical evaluation thresholds. Ultimately, our method is designed to meet crucial requirements in E&L studies, ensuring efficient and cost-effective protection against potentially harmful substances. Don't miss this opportunity to stay at the forefront of E&L research.

Learning points:

• determine which analytes behave as non-volatiles with CAD and can therefore be accurately quantified using surrogate standards

• improve quantification accuracy and reduce response factor variation using an inverse gradient

• use an in-line mixer to combine the analytical and inverse gradients and improve response uniformity

Who should attend:

• Laboratory managers and directors

• Technology leaders

• Principal scientists

• Laboratory analyst
