Jacqueline L. Mann

Jacqueline’s employment at NIST began with the measurement of sulfur concentration by isotope dilution thermal ionization for certification of fossil fuel (coal, diesel fuel, fly ash, gasoline, etc.) and other Standard Reference Materials (SRMs).  This activity evolved into the development of a high-precision technique for the measurement of sulfur isotope composition of these and other environmental materials with sub-micromolar quantities of sulfur. More recently, measurements of moisture and other additional analytes including chlorine and mercury have been a part of her activities. Currently, she is also actively involved with learning new analytical techniques for isotopic measurements associated with the NIST Isotopic Reference Material Program. She has authored or co-authored 13 peer-reviewed publications describing these activities.
