Mass spectrometry has played an integral part in the study of organic molecular structures for more than 50 years, offering significant information from small amounts of sample. The mass spectrum produced by electron impact ionization presents a pattern of peaks that can often give definitive structural information about an unknown compound.

Biography

Stephen Shrader , founder of Shrader Analytical and Consulting Laboratories, was among the early third-generation mass spectroscopists, starting in 1963. He is an internationally recognized expert in the use of mass spectrometry for structural elucidation and resolution of chemical problems in the petroleum, pharmaceutical, environmental, and polymer fields. His work has included periods in academia, the pharmaceutical industry, and a long stint as a consultant to the overall chemical industry. Throughout his 40-plus-year career, he has shared his experiences and knowledge of mass spectrometry via numerous seminars and classes. He has also been instrumental in developing a set of software tools called TSS Unity for displaying, printing, and evaluating mass spectral data for the purpose of solving chemical problems.
