Title: Innovations of Jill A Marshall
Introduction
Jill A Marshall is a prominent inventor based in San Antonio, TX (US). She has made significant contributions to the field of mass spectrometry, holding 2 patents that showcase her innovative spirit and technical expertise.
Latest Patents
Her latest patents include a time of flight mass spectrometer and an ion source, along with methods of preparing a portable time of flight mass spectrometer using plasma desorption sample ionization. In her inventions, the sample is deposited onto a sample surface by condensing a sample gas stream onto the surface. While the instrument is evacuated, the sample surface is cooled, and a sample gas stream is injected into the instrument near the sample surface. This process causes a portion of the gas stream to condense on the sample surface, while the remainder is removed by the evacuation pump. Her designs include a mass spectrometer with a linear geometry and a reflective geometry, maximizing the flight path length by placing the fission source between the sample surface and a single detector. Additionally, she has developed a collector surface for receiving start signal-generating fission fragments, ensuring equal collection of start signal fragments and sample ionizing fragments.
