The introduction of USP<232> and ICH Q3D requires the pharmaceutical industry to re-evaluate how elemental impurity (heavy metal) testing is performed.  ICP-MS is often used for this type of analysis, but requires a high level of user expertise and can be time-consuming.  USP <735> and EP 2.2.37 enable the use of X-ray fluorescence (XRF) spectrometry as an alternative technology for pharmaceutical elemental impurity testing.  In this webinar, the capabilities of the Epsilon 4 benchtop system set up with our unique calibration solution to analyze elemental impurities according to current regulatory requirements, will be demonstrated.
