O. David Sparkman is a consultant to the National Institute of Standards and
Technology Mass Spectrometry Data Center, an Adjunct Professor of Chemistry at
the University of the Pacific in Stockton, CA, and long-time instructor of
various mass spectrometry courses for the American Chemical Society. Professor
Sparkman has extensive experience in the development of GC/MS, LC/MS, and other
mass spectrometry applications. He currently directs the mass spectrometry
facility in the Department of Chemistry of the University of the Pacific, which
supports the university's School of Pharmacy as well as the Departments of
Biology and Chemistry. This mass spectrometry facility has collaborations with
industry and other universities. During his career, Professor Sparkman has
worked with several mass spectrometry companies in product development and
marketing capacities. Professor Sparkman has published several papers relating
to the use and development of mass spectral databases in conjunction with his
work for NIST. He has written for the Journal of the Society for Mass
Spectrometry (JASMS), the Mass Spectrometry Review of the Pittsburgh
Conference on Analytical Chemistry and Applied Spectroscopy for the past
eight years. Professor Sparkman sits on the editorial advisory boards of a
number of mass spectrometry journals, data sources, and encyclopedias; and
frequently writes book and conference reviews for JASMS. He is the author of
Mass Spectrometry Desk Reference; Global View Publishing: Pittsburgh, PA
(http://www.lcms.com). In addition, it has
been reported that he has the largest single collection of
mass spectrometry and journals assembled in a single place. As
a member of the Bolton Society, Professor Sparkman is a registered
bibliophile.
Professor Sparkman developed the seamless interface between the NIST Mass
Spectral Search Program and the GC/MS and LC/MS ChemStations. He worked on the
development of macros for the interface of NIST's Automated Mass spectral
Deconvolution and Identification System (AMDIS) to the GC/MS ChemStation. He
also worked on the development of a GC/MS ChemStation macro that enables the
searching of up to three different libraries with the best hits being returned
from all three. He has written or caused to be written a number of other
routines that have enhanced the data analysis capabilities of the GC/MS
ChemStation. Professor Sparkman continues to be a frequent contributor to the
sci.techniques.mass-spec News Group.
As one of the original founders of
ChemUserWorld.com, Professor Sparkman has the vision of a single-point source
for information relating to getting the maximum results through GC/MS and LC/MS
using the ChemStation and other GC/MS and LC/MS data systems.

Charlie holds a Ph.D. in Organic Analytical Chemistry from Pennsylvania State
University. After his postdoctoral fellowship developing applications for FT
Mass Spectrometry at UC Riverside, Charlie worked for HP (Agilent) as an
Application Engineer for 13 years, where he developed software solutions and
training classes to support HP ChemStations.
For the last 4 years Charlie has run his own independent consulting firm where
he specializes in developing software solutions for scientific laboratories.
His clients have included Abbott labs, Glaxo, Genentech, Pfizer, Merck, Rohm and
Haas and several other companies.
Through ChemUserWorld.com, Charlie hopes to further apply his knowledge and
skills to help customers solve their problems via training classes, custom macro
and software development, and plain old good advice.

Alex works for the Queensland Government Racing Science Centre.
He received his B.Sc. in Chemistry in 1992 and M.Sc. in Forensic Science in 2001,
both from Griffith University. He has also worked for the Queenland Government
Chemical Laboratory. He has created custom macros and programs that have
contributed to increases in productive and reliability.
He is interested in promoting solutions to increase the ease of use of Chemstation,
enabling users to concentrate on their tasks, and increasing throughput.
He is also interested in developing trace analysis of target compounds using GC/MS
Chemstation macros.
His other areas of interest include:
- Operation, troubleshooting and maintenance of Agilent mass spectrometers
- Data file creation
- Visual Basic programming
