He has made significant contributions to the field of mass spectrometry, with a focus on techniques for quantifying molecules and efficient fragmentation of peptides. His work has led to the development of two patents that enhance the capabilities of mass spectrometry.

Latest Patents

Johannes P C Vissers holds two patents that showcase his innovative techniques. The first patent, titled "Techniques for quantification of samples," describes methods for quantifying molecules in a sample using mass spectrometry. This technique involves obtaining ionization intensities for precursor and product ions from a specific molecule. A first set of precursor ions with the highest ionization intensities is determined, followed by identifying a second set of product ions associated with each precursor. The intensity sum for the molecule is calculated and compared to a calibration standard to determine the quantity of the molecule in the sample.

The second patent, "Techniques for efficient fragmentation of peptides," outlines methods for performing mass spectrometry. In this technique, a stream of ions is generated and transmitted into a collision cell. The collision energy is selected based on criteria such as the retention time of precursor ions, allowing for the generation of product ions from the precursor ions in the stream.
