About Us

Gary W Yanik

Extensive expertise in applying physics, mathematics, engineering, software, and chemistry to the development and volume manufacture of successful instruments and systems. Design and development skills include optics/lasers, electronics, mechanics, and software. Application skills include HPLC/UPLC/SFC/CCC/SMB and especially method development, prep purification, and process control.

BS in Physics, Mathematics, and Chemistry at University of Michigan (1970) and Engineering Management degree from California Institute of Technology. At University of Michigan developed instrumentation to accurately measure g-factor of positrons (anti-particles); at Hale Observatories developed photon-counting imaging spectrometers and polarimeters for characterizing distant galaxies and the expansion of the Universe; as Technical Director at Hughes Aircraft and United Technologies (aerospace) developed multi-sensor suites for detection and tracking of ballistic missiles (SDI) and laser radar guidance systems for cruise missiles; as VP of Product Development at Thermo Separation Products developed photodiode array detectors, autosamplers, and HPLC pumps.


PDR-Separations is an instrument manufacturing company focused on services and hardware/software products for method development, prep purification, and process control, especially in HPLC/UPLC/SFC/CCC/SMB applications. Services include: practical lab automation complete with on-site training and SOIP (Service Over Internet Protocol; designing/installing unique automation systems; helping customers do more with less. Products include: 4th generation Advanced Laser Polarimeter (4G-ALP); Software for automating Method Development (AutoMDS), Prep (AutoPrep), and AutoCCC for method development and prep collection with CCC systems; 10/20 bottle Low Pressure Gradient Mixers, 12/24 position Column Selectors with heating/cooling; Prep Injector/Collectors; and Composition/Concentration Monitors (CCM) that “look into flowing streams” and plot real-time concentration of chemical components.
