Lu Yang received her BSc and MSc in Chemistry from Nanjing University (Nanjing, China) in 1987 and University of British Columbia (Vancouver, Canada) in 1993, respectively. Since 1994, she has been working at Chemical Metrology, Institute for National Measurement Standards, National Research Council of Canada (NRCC). In 2004, she received her PhD in Chemistry from Carleton University (Ottawa, Canada). Presently, she is a Research Officer at NRCC. Her research activities encompass three major areas. 1) The development of innovative methods for trace and ultra-trace metal analyses by isotope dilution ICP-MS. This includes the development and use of on-line column preconcentration/matrix separation of trace metals, on-line vapor generation of trace metals, laser ablation, improved digestion and sample decomposition procedures for marine sediments and biological matrices with microwave assisted digestion techniques, and novel SPME preconcentration procedures for volatile element species. 2) The development of accurate and precise methodologies for the determination and quantitation of speciated forms of metals such as, Se, Hg and Sn in various sample matrices by SPME, GC, and HPLC, in combination with ICP-MS detection or by GC-MS detection. 3) The development of cutting edge methodologies for accurate and precise isotope ratio measurements using MC-ICP-MS. This includes the production of CRMs with certified isotopic compositions, applications in isotopic fractionation studies, provenance studies of foods and natural health products, and applications in fingerprinting sources of elements in the environment. In addition, she is responsible for managing CCQM (Consultative Committee on Amount of Substance of CIPM) projects (such as CCQM-K13, CCQM-P15, CCQM-K29, CCQM-K43, CCQM-P18, CCQM-P62, CCQM-P86, CCQM-P105 and CCQM-K75) to ensure NRCC’s calibration and measurement capabilities in Chemical Metrology area and maintain the expert level proficiency.
