24 targeted elemental impurities in three drug products were determined following new USP chapters <232>/<233> using Shimadzu ICPMS-2030. The method was evaluated and validated according to the procedures defined by USP <233> and combined with microwave digestion for sample preparation. Good calibration linearity, repeatability, stability and specificity were achieved for all 24 impurities. Low LODs and LOQs were obtained as compared to the target limits from USP <232>. The ICP-MS method applying universal He collision mode provides a high throughput method for routine elemental impurity analysis in pharmaceutical products.
