Latest Patents

One of his latest patents is titled "Pulsed mass calibration in time-of-flight mass spectrometry." This patent describes a method for calibrating mass-to-charge ratio measurements obtained from a time-of-flight mass spectrometer used as a detector for a chromatographic system. The method involves introducing a calibrant material into the mass spectrometer after a sample is introduced, ensuring that the calibrant and sample materials do not coexist at the ion source during analysis. This innovative approach allows for the acquisition of multiple mass spectra of the calibrant material during an analytical run, facilitating accurate mass calibrations.

Another significant patent is the "Method and apparatus for measuring velocity of chromatographic pulse." This invention utilizes thermal modulation in a two-stage chromatographic separation process. The apparatus features a loop structure in the chromatographic column or modulation tube, allowing for simultaneous thermal modulation of two portions by at least one thermal modulation device. This advancement enhances the efficiency and effectiveness of chromatographic separations.
