Latest Patents

Igor Chemushevich holds a patent titled "Precursor accumulation in a single charge state in mass spectrometry." This invention involves an ion source that ionizes a compound, producing precursor ions with varying m/z values. A reagent source supplies a charge-reducing reagent, while an ion guide is strategically positioned between the mass filter and both the ion source and the reagent source. The ion guide applies an AC voltage and DC voltage to its electrodes, creating a pseudopotential that traps the precursor ions below a certain threshold m/z. The AC voltage facilitates the charge reduction of the trapped precursor ions, allowing their m/z values to increase to a single value above the threshold. Consequently, the ion guide applies a DC voltage relative to the mass filter's electrodes, enabling the continuous transmission of the precursor ions to the mass filter.
