A brief history of my experiences in using extra-lab resources:

a.LSD by GC/MS in the Chemistry Dept. at Florida State University, 1971

b. ATR FTIR of a rubber fragment from an automobile bumper guard run at the Nicolet Lab in Frankfurt, Germany, 1980

NMR198?: Identification of a suspicious white powder at the NMR Lab of the Höchst AG Chemical Corporation in Frankfurt, Germany after examinations at the U.S Army Criminal Investigation Laboratory-Europe using FTIR, GC/MS, and X-ray diffraction had failed to come up with an identification.

200?: Identification of a suspicious white powder with the Chair of the Chemistry Department at USD using their NMR

DCI/MSCondom Lubricant Detection/Identification in two Rape Cases using Desorption Chemical Ionization with a magnetic sector MS

PDMS Condom Lubricant Nonoxynol-9 Condom Spermicide

Both obtained my Dr. Marco Vincenti, Chemistry Department, University of Torino, Torino, Italy ~ 1994

~1995 – 2006 ESI MS; Nano-Spray Ionization MS; MALDI TOF MS; & DIOS MS at Dr. Gary Siuzdak’s Mass Spectrometry Lab at the Scripps Research Institute, La Jolla, CA
