Title: Innovations by Stephen R Bakalyar

Introduction

Stephen R Bakalyar is a notable inventor based in Berkeley, California. He has made significant contributions to the field of chromatography through his innovative designs and patents. With a total of three patents to his name, Bakalyar has focused on enhancing the efficiency and effectiveness of sample injection systems.

Latest Patents

One of his latest patents is an "Injector with minimal flow-interrupt transient." This invention describes an injector designed for injecting a sample at high pressure into a chromatographic column. It effectively avoids sample dilution, which is often a problem with bypass loop injectors, and minimizes flow interruption, a common issue with non-bypass injectors. The design includes a stator with pump and column ports that feature openings spaced at a small angle from one another. This innovative approach ensures that as the injector transitions from load to inject positions, there is only a brief interruption of liquid flow into the column.

Another significant patent is the "Sample injector," which is designed to receive a sample at atmospheric pressure and inject it at high pressure into a chromatographic column. This device is user-friendly and prevents sample loss. It features a rotor and stator with flat adjacent faces, along with a passage in the rotor for receiving a syringe needle. This design allows for the complete transfer of the sample into the stator port, ensuring that no sample remains in the rotor passage after operation.
