Title: Innovations of John E Brann, III
Introduction
John E Brann, III is an accomplished inventor based in Boylston, MA (US). He has made significant contributions to the field of chemical analysis, holding a total of 2 patents. His work focuses on the separation of compounds in liquid mixtures, showcasing his expertise in chromatographic techniques.
Latest Patents
Brann's latest patents revolve around a system designed for separating compounds of relatively low molecular weight from those of high molecular weight. This innovative system utilizes a chromatographic column packed with uniformly distributed rigid, solid, porous particles. These particles have chromatographically active, hydrophobic surfaces, with average diameters of not less than about 30 micrometers. The average pore diameters are sufficiently small to exclude the introduction of high molecular weight compounds into the pores. The mixture is pumped through the interstitial volume between the particles at a reduced velocity greater than about 5,000, allowing a band of high molecular weight compounds to exit the column. The low molecular weight compounds are then eluted and recovered separately, with spectrographic identification made possible through methods such as ultraviolet absorption or mass spectrography.
Career Highlights
Brann is currently associated with Cohesive Technologies, Inc., where he continues to innovate and develop new technologies in chemical analysis. His work has been instrumental in advancing the methodologies used in the separation of chemical compounds.
