Friso van Amerom has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9589776
    Abstract: A dual-ionization mass spectrometer includes a first mass spectrometer module forming a hard ionization mass spectrometer, a second mass spectrometer forming a soft ionization mass spectrometer, a vacuum ultraviolet light source positioned between the first and second modules, a housing encompassing the first and second sets of plates and the light source, and an inlet positioned to receive a sample of an analyte and provide it to at least one of the sets of plates. A method of detecting a substance includes receiving a sample of an analyte into a housing through an inlet, performing soft ionization mass spectrometry on the sample with a soft ionization mass spectrometer in the housing, performing hard ionization spectrometry on the sample with a hard ionization spectrometer in the housing if needed, and generating a detection result from at least one of the soft ionization spectrometry and the hard ionization spectrometry.

  • Patent number: 9190258
    Abstract: The present disclosure discusses a system and method for continuous operation of an ion trap mass spectrometer. The described system does not introduce ions into the ion trap in distinct trapping phase, rather the described system continuously injects ions into the ion trap while continuously scanning out the ions. The system and method described herein achieves a much higher duty cycle and cycle rate when compared to standard mass spectrometer devices.

  • Patent number: 8188422
    Abstract: A die assembly for creating a ring electrode including a cylindrically-shaped die base, two die walls and a die top sized to fit inside a cylindrical die housing. The die base and die top having a series of concentric elevations used as impressions to form on two ends of the ring electrode. A method of fabricating an LTCC ring electrode using the die assembly is also provided.

  • Patent number: 7700911
    Abstract: A cylindrical ion trap (CIT) mass spectrometer constructed using a non-conductive substrate (LTCC) as the basis for the ring electrode. Photolithography and electroless plating were used to create well-defined conductive areas on the LTCC ring electrode. The inventive method allows for the precise control of establishing conductive areas on a non-conductive substrate through the steps of punching, lamination, firing, metallization and photolithography on the metallized layer.
