Considering these challenges that impurities cause to the petrochemical industry, it is critical for laboratories to monitor the levels of impurities (e.g., metals and sulfur) in common petrochemical products with highly sensitive methods. This podcast, from Thermo Fisher Scientific, will discuss how advances in elemental mass spectrometry systems are enabling rapid and accurate element analysis of impurities, and how small changes in the sample introduction system—such as the use of ceramic torches—are further boosting operational capacities.
