∙ Metals Speciation and Incremental Sampling Methodologies

Dr. Mark Bruce

Corporate Technical Director, TestAmerica

Dr. Mark Bruce has over 35 years of environmental analytical chemistry experience in academic and commercial laboratories. He has led method development and modification projects for both organic and inorganic analyses, which include arsenic speciation, methyl mercury, low-level mercury, vapor space organics, leaching and incremental sampling methodology (ISM). Dr. Bruce has been actively involved with the Interstate Technology and Regulatory Council (ITRC) committee for ISM, and he is a recipient of the ITRC Industry Recognition Award for his contribution. He also has experience developing custom cleanup methods to address sample specific interferences.

As Corporate Technical Director, Dr. Bruce's duties include investigation and implementation of new technology, process improvement, and leading technical project teams within TestAmerica. His method development work has involved incremental sampling methodology, mercury, metals speciation and organic extractions.

Dr. Bruce earned his BS in Chemistry at the University of Mount Union, OH, and his Ph.D. in Analytical Chemistry at the University of Cincinnati, OH.
