Title: The Innovations of Stephen F. Barker
Introduction
Stephen F. Barker is a notable inventor based in La Mirada, California. He has made significant contributions to the field of chemistry analysis through his innovative designs. With a total of six patents to his name, Barker has established himself as a key figure in the development of automatic chemistry analyzers.
Latest Patents
One of Barker's latest inventions is an automatic chemistry analyzer. This device features a flow cell that is mounted in a way that allows visibility of the flow through the cell and the connected tubing from the front of the housing. The electrolytes for the cell can be easily plugged in from the rear. The probe that aspirates sample fluid into an injection cell is designed to be simultaneously washed by diluent, which mixes with the fluid sample. Waste fluid from the flow cell is directed to a basin that feeds under gravity to a waste drain. A ratio pump, formed by selected syringes, is band-driven to deliver precise volumes of reagents to the flow cell. The solution ground to the system is located on the inlet line for the sample, minimizing electronic noise. The design requires only two motive means: one for horizontal and rotational movement of the sample tray, and another for vertical motion of a crane-mounted probe that operates between sample cups and the injection cell.
