Latest Patents
One of his latest patents is the "Interface for liquid chromatograph-mass spectrometer." This invention features a moving belt interface designed for real-time, high-performance liquid chromatograph (HPLC) and mass spectrometer (MS) analysis. It effectively strips away the HPLC solvent as it emerges from the end of the HPLC column, leaving a residue suitable for mass-spectral analysis. The interface includes a portable, stand-alone apparatus with a multi-stage vacuum station, a continuous ribbon or belt, and a calibrated HPLC delivery system. Additionally, it has a heated probe tip and means for direct ionization of the residue on the belt, making it adaptable to fit any mass spectrometer.
Another significant patent is for "Radial thin layer chromatography." This invention presents an improved liquid chromatography column that utilizes a horizontal flow of liquid through the separating medium. The improved fluid distribution system includes a screen or mesh arrangement, allowing for uniform distribution of the sample or eluting fluid radially around the periphery of the separating medium bed. This innovation eliminates the high machining costs and other issues associated with traditional systems.
