With a total of 2 patents, his work showcases innovative solutions that enhance analytical techniques.
Latest Patents
Xie’s latest patents include an "Integrated column and detector in a module for liquid chromatography." This invention presents a system and method for separating the functions of a liquid chromatography (LC) system into physically separate systems. This allows for a more versatile LC system, where an LC device provides column liquid solvent, a sample, and a pump and injector that pushes the sample in the solvent to an output port. The attachable module contains a module input port, a column, a heater for the column, and at least one detector for on-column detection. This design enables the sample in the solvent to be pumped through the column to the detector, facilitating the separation, identification, and quantification of substances in the sample.
Another significant patent is the "Simple equilibrium distribution sampling device for GC-MS calibration." This system provides standard mixtures of volatile and semi-volatile organic compounds for simultaneous GC and MS calibration in a calibration vial. Calibration mixtures are prepared by diluting calibration analytes in granular PDMS, ensuring that most analytes are in the PDMS phase. This method allows for reliable calibration samples to be taken from the headspace vapor in the calibration vial, offering solvent-less sampling, long-time stability, and ease of use.
