Marcela Najarro (Fed)
Marcela Najarro has been a research chemist at NIST since 2005. Her professional background is in Forensic Chemistry/Toxicology, with an emphasis in the detection and identification of drugs of abuse. Her current research interests include the generation of trace explosives standards to verify the proper operation of Ion Mobility Spectrometry (IMS) instruments, establish detector response criteria, and be used for calibration purposes. This effort includes developing and validating methods for the high precision quantification of trace explosives standards using Gas Chromatography/Mass Spectrometry and Ultraviolet-Visible spectroscopy (UV/Vis) and the evaluation of multi-variable data sets using statistical analysis.
