The Department of Energy (DOE) National Nuclear Security Administration (NNSA) has a specialized need for analyzing low mass gas species at very high resolutions. The currently preferred analytical method is electromagnetic sector mass spectrometry. This method allows the NNSA Nuclear Security Enterprise (NSE) to resolve species of similar masses down to acceptable minimum detection limits (MDLs). Some examples of these similar masses are helium-4/deuterium and carbon monoxide/nitrogen. Through the 1980s and 1990s, there were two vendors who supplied and supported these instruments. However, with declining procurements and down turns in the economy, the supply of instruments, service and spare parts from these vendors has become less available, and in some cases, nonexistent.


Dr. Steven Wyrick is the current President of the Institute for Nuclear Materials Management (INMM) Southeast Chapter and has been a member of INMM for four years. Dr. Wyrick is the Surveillance Program Manager for Gas Transfer Systems at the Department of Energy (DOE) National Nuclear Security Administration (NNSA) Savannah River National Laboratory (SRNL). He is currently performing a detail assignment at the National Nuclear Security Administration (NNSA) Headquarters, where he is a member of the Science Council in the Office of Defense Programs. At SRNL, Dr. Wyrick previously held positions of Manager, Weapons Technology Group; Manager, Defense Programs Engineering Technology; and Senior Scientist Subject Matter Expert, Mass Spectrometry. Dr. Wyrick earned his PhD in Physical Chemistry at the University of Cincinnati.
