Title: Randy W. Purves: Innovator in Mass Spectrometry and FAIMS Technology
Introduction
Randy W. Purves is an accomplished inventor based in Orleans, California, known for his significant contributions to the field of mass spectrometry and ion mobility spectrometry. With a remarkable portfolio of 12 patents to his name, Purves has demonstrated an unwavering commitment to advancing scientific innovation.
Latest Patents
Among his latest patents is the "Quadrupole FAIMS apparatus," which presents a combined rf-only/FAIMS analyzer for mass spectrometry applications. This innovative apparatus features a series of flat-plate electrodes arranged around a longitudinal axis, forming a parallelogram in cross-section. The FAIMS functionality can be electronically removed when not in use by applying tailored radio frequency waveforms to the electrodes.
In addition, he developed a "Method for distinguishing between protein variants," which employs high field asymmetric waveform ion mobility spectrometry (FAIMS). This method entails establishing a FAIMS analyzer region defined by spaced electrodes, introducing ions of analyte proteins generated from a specific solution using an ionization source, and enabling the measurement of detected ions at predetermined conditions. The sophisticated technique facilitates the identification of protein variants based on intensity differences against a reference value related to the expected intensity for a reference form of the analyte protein.
