Title: The Innovations of Stephen Fuerstenau

Introduction

Stephen Fuerstenau is an accomplished inventor based in Montrose, CA (US). He has made significant contributions to the field of mass spectrometry, particularly in the analysis of large molecules. His innovative approach has led to the development of a unique apparatus that enhances the capabilities of mass spectrometers.

Latest Patents

Fuerstenau holds a patent for an "Apparatus and method of determining molecular weight of large molecules." This invention involves a mass spectrometer that determines the mass of multiply charged high molecular weight molecules. The device utilizes an ion detector capable of simultaneously measuring the charge z and transit time of a single ion as it passes through the detector. From this transit time, the velocity of the single ion can be derived, allowing for the calculation of the mass-to-charge ratio m/z for a single ion accelerated through a known potential. The technology enables the detection of electrospray ions with masses exceeding 1 MDa and charge numbers greater than 425 e.sup.-. The on-axis single ion detection configuration allows for a nearly 100% duty cycle, extending the practical application of electrospray mass spectrometry to the analysis of very large molecules with relatively inexpensive instrumentation.
