Title: Joël Lemaire: Innovator in Ion Trap Technology
Introduction
Joël Lemaire is a notable inventor based in Antony, France. He has made significant contributions to the field of mass spectrometry through his innovative patents. With a total of 2 patents, Lemaire's work focuses on advanced ion trap technologies.
Latest Patents
Lemaire's latest patents include an "Ion trap with longitudinal permanent magnet" and a "mass spectrometer using the same." The vacuum magnetic ion trap features an assembly forming a permanent magnet, which includes at least two magnetized structures in the form of hollow cylinders. One of these structures is a convergent radial structure, while the other is a divergent radial structure. These structures are arranged along a common longitudinal axis. The trap also contains a sealed chamber with an anion confinement cell fixed between the magnetized structures, which includes trapping electrodes connectable to a voltage generator.
His second patent, "Permanent magnet ion trap and a mass spectrometer using such a magnet," describes a vacuum ion trap that includes a gastight processing enclosure and a permanent magnet defining a cavity. This cavity creates a directed magnetic field, and the enclosure contains a confinement cell with mutually parallel trapping electrodes. These electrodes are perpendicular to the directed magnetic field and are also connectable to a voltage generator. This innovative trap is particularly applicable to Fourier transform mass spectrometry (FTICR).
