Title: Andre L'heureux: Innovator in Mass Spectrometry
Introduction
Andre L'heureux is a notable inventor based in Levis, Canada. He has made significant contributions to the field of mass spectrometry through his innovative patents. With a total of 2 patents, L'heureux has developed technologies that enhance the analysis of samples in various scientific applications.
Latest Patents
One of L'heureux's latest patents is the "Sample support for desorption." This invention provides an apparatus and method for regenerating ion samples for a mass spectrometer. The design allows source samples to be loaded on a support that is heated by a laser beam, desorbing the sample without ionization. The desorbed sample is then carried by a carrier gas flow through a transfer tube, where it is ionized by corona discharge or photo-ionization. This ionized sample can be analyzed in a mass spectrometer or utilized for other appropriate purposes.
Another significant patent is the "Metastable atom bombardment source." This invention offers a charged particle-free beam of metastable species that can bombard and ionize organic and inorganic substances in a gas phase. The metastable atoms are produced by inducing a discharge in a gas, such as rare gases or small molecules. The discharge is curved between the cathode and anode, with the cathode located in a medium pressure zone and the anode positioned off-axis in a low pressure zone. A nozzle situated between the cathode and anode provides a collimated beam of metastable atoms of low kinetic energy directed at an ion volume containing the substances to be analyzed.
