Analysis of Residual Metal Catalysts Using ALTRACE

This Application News presents the use of the ALTRACE Energy Dispersive X-ray Fluorescence (EDXRF) spectrometer for determining residual levels of metal catalysts in organic compounds. The document outlines the capabilities of ALTRACE, which can detect heavy metals at concentrations as low as 1 mg/kg in under 10 minutes. It details the analysis of palladium (Pd) as a catalyst in a Suzuki-Miyaura cross-coupling reaction, emphasizing the importance of managing residual catalysts for safety and cost reasons. The methodology includes sample preparation, calibration curve generation, and the effectiveness of using metal scavengers and activated carbon for catalyst removal. The results indicate a high accuracy in measuring Pd concentrations, with a coefficient of variation of only 2.3%. The document concludes that EDXRF spectrometry offers a reliable method for assessing elemental impurities, making ALTRACE a valuable tool in industrial applications.
