Title: William Daniel Frazer: Innovator in Mass Spectrometry
Introduction
William Daniel Frazer is a prominent inventor based in Mountain View, CA (US). He has made significant contributions to the field of mass spectrometry, holding a total of 10 patents. His work focuses on enhancing the resolution of mass spectra, which is crucial for various applications in scientific research and analysis.
Latest Patents
Frazer's latest patents include a mass spectrometer and a method for enhancing the resolution of mass spectra. The mass spectrometer he developed comprises an ion detector, an analog-to-digital (A/D) converter, a sample adjuster, and an adder. The A/D converter generates digital samples representing an analog signal received from the ion detector during a mass scan. The adder sums the samples with corresponding unsuppressed samples from previous mass scans, defining a mass spectrum. The sample adjuster identifies a peak defined by the samples and suppresses all but one of the samples defining the identified peak to enhance resolution.
Another notable patent is the enhanced resolution mass spectrometer and mass spectrometry method. In this process, a mass spectrum is generated from a mass scan signal comprising original samples defining a peak. A subset of these original samples is selected, and one or more synthesized samples are created from this subset. These synthesized samples provide greater temporal resolution than the original samples and are summed with temporally-aligned accumulated samples from previous mass scans to produce the final mass spectrum.
