Tom Jupille has been a practicing chromatographer for more than 30
years, during which he has written more than 30 papers on
chromatography and related subjects. He worked primarily in gas
chromatography in the late '60s, switching to thin-layer chromatography
in the early '70s and then to HPLC and ion chromatography in late '70s.
His career has focused on instrument and column development and user
support, providing a broad foundation of practical experience.
Tom is the resident Microsoft Excel and Powerpoint guru at Separation
Science Associates. Over the past 18 years, he has presented courses
and seminars in the field of chromatography to more than 3000 students
as well as preparing, editing, or coaching the presentation of dozens
of papers and seminars. In addition to teaching, he has been involved
in the development and support of computer modeling techniques for
chromatography method development. He is the Moderator of the popular
on-line discussion group Chromatography
He is a Consulting Editor for LCGC Magazine and Associate
Director of the California Separation Science Society (CASSS).
John Dolan John Dolan's 20-plus years as author of LCGC's
popular "LC Troubleshooting" column, co-author of Troubleshooting
LC Systems, and 20 years of teaching short courses for LC Resources
have earned him a reputation as one of the world's top troubleshooters.
John was a member of the team that developed DryLab® software, and
his research on gradient elution has helped move this important
separation technique from a research tool to routine use.
Dr. Dolan's 30 years of experience in HPLC have resulted in 100
scientific papers, more than 225 installments of the monthly "LC
Troubleshooting" column, and countless presentations. He has worked in
instrument design, software development, professional training, and
laboratory management. In 1984, he and Lloyd Snyder started LC
Resources. In 2002, LC Resources Laboratory Services group was sold to
Bioanalytical Systems (BASi), with John serving as Vice President
General Manager of BASi Northwest Laboratories, a division of BASi that
specializes in method development, validation, and application of LC
and LC-MS/MS methods for the analysis of pharmaceuticals in biological
samples. He is currently Vice President and Director of Training for LC
John's expertise can be
used to help solve separation and instrument problems, train your
staff, or as a sounding board for new ideas.
||Lloyd Snyder is widely
regarded as one of the "founders" of HPLC and is well known for his
40+ years of experience and research in the field of liquid chromatography. He has written more than 200 HPLC-related papers and
has taught HPLC courses to more than 10,000 students since 1971.
He is coauthor of the three standard HPLC texts:
- Introduction to Modern Liquid
- Practical HPLC Method
- Troubleshooting HPLC Systems.
Dr. Snyder's contributions to
the development of HPLC have been recognized by a number of
international awards, including the ACS awards in chromatography and
the Pittsburgh Analytical Chemistry Award. Dr. Snyder is heavily
involved in designing strategies for effective HPLC method development
as well as in developing training materials and course content to
communicate these strategies to the chromatography community.
Dr. Snyder's unsurpassed
understanding of chromatography gives him a unique ability to extract
useful information from masses of baffling and seemingly unrelated
Hallenburg holds the distinction of having the longest tenure
(eight years) as editor of LCGC Magazine. She has also served
as founding editor of LCGC International and Managing Editor
of the Journal of Microcolumn Separations. Kari combines a
solid understanding of chromatography, 20 years of professional writing
and editing experience, and well-honed skills at page layout, technical
writing, graphic design, and web site design to provide world-class
support for scientific communications. She has worked in the areas of
chromatography, spectroscopy, pharmaceutical technology and business,
cosmetic technology, medical training, and health care.
has over 40 years' experience in separation technology, with a focus on biochromatography. He has worked on HPLC instrument and column development, and has developed capillary electrophoresis instruments, separation chemistries, and applications. He has over ten years' experience with mass spectrometry and LC-MS, and worked with quadrupole, ion trap, and MALDI TOF-TOF instruments.
Dr. Wehr has published over 20 peer-reviewed research papers, four books on separation science, and numerous book chapters. He is coauthor of the popular textbook HPLC and CE of Biomolecules. He was cofounder of the International Symposium on HPLC of Proteins, Peptides and Polynucleotides, and served as editor for the Journal of Chromatography Symposium Series. He served as a columnist for LC-GC magazine, publishing Directions in Drug Discovery.
He has extensive teaching experience, having taught chromatography and biochromatography courses for UC Berkeley, Ohlone College, and LC Resources.
