Simple and robust ICP-MS method for simultaneous determination of serum Co and Cr in routine clinical practice

ICP-MS can simultaneously quantify serum Cr and Co levels with suitable analytical performance including a wide analytical range and very low LOQ. This assay will be very useful for evaluating the nutritional status of Cr and Co in healthy humans as well as monitoring the performance of orthopedic prostheses after hip resurfacing arthroplasty.
