William Brewer, PhDPresident and CEO

As president and CEO of DPX Technologies, Dr. Brewer (Bill) leads a biotechnology company focused on providing creative solutions for complex sample preparation.

Bill originated the idea for a solid-phase extraction device while working for the S.C. Law Enforcement Division as a forensic toxicologist. His goal was to streamline sample preparation by transferring liquid samples and performing extractions within a pipette tip. Dr. Brewer obtained a patent for a “Disposable Pipette Extraction” (DPX) device in 2000. This flagship technology has since been improved and rebranded as Dispersive Pipette XTRaction.
