Title: The Innovative Contributions of Harald Oser
Introduction
Harald Oser is a notable inventor based in Menlo Park, CA (US). He has made significant contributions to the field of analytical chemistry, particularly in the detection and identification of trace organic substances. With a total of 2 patents, Oser's work has advanced the capabilities of mass spectrometry.
Latest Patents
Oser's latest patents include a method and apparatus for the detection and identification of trace organic substances from a continuous flow sample system using laser photoionization-mass spectrometry. This innovative method allows for the identification of analytes at low concentrations in a liquid sample. The liquid sample is introduced through a continuous flow membrane inlet system, where analytes that permeate the membrane are analyzed by photoionization-time-of-flight mass spectrometry. Additionally, any analytes remaining in the liquid sample that do not permeate the membrane are conducted to a capillary tube inlet for further analysis. The apparatus also allows for the application of heat to drive analytes remaining absorbed on the membrane through it. Oser's second patent, a direct liquid injection inlet to a laser photoionization apparatus, provides a method for analyzing an analyte at low concentration in a liquid sample. This system allows for a significant improvement in the lower detection limit of an analyte compared to conventional methods.
