Steven J Christopher

Research

Dr. Christopher's current research focuses on developing reference analytical methods for the determination of trace elements in NIST Standard Reference Materials, research on petroleum materials, isotopic chemical forensics measurements via multicollector ICP-MS, investigating novel instrument couplings, and solid-sampling and imaging research using laser ablation interfaced to ICP-MS. He is an adjunct professor at the Medical University of South Carolina's Marine Biomedicine and Environmental Sciences Center.

Experience

Dr. Christopher has 20+ years of research experience in plasma-based spectroscopies, including inductively coupled plasma and glow discharge plasma mass and emission spectrometries, sector field ICP-MS and multicollector ICP-MS; Comprehensive knowledge of analytical instrumentation and method development for quantification of trace elements; experience with trace element and isotopic chemical separations and microwave sample decomposition methodologies; application of quantification strategies employing high-accuracy measurement and calibration schemes, including isotope dilution mass spectrometry, method of standard additions and mercury quantification methods.
