Ayumi Kubo

Title: Ayumi Kubo: Innovator in Mass Spectrometry

Introduction

Ayumi Kubo is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of mass spectrometry, holding a total of 10 patents. Her innovative work has advanced the methods and technologies used in sample analysis.

Latest Patents

Among her latest patents are two notable inventions. The first is a "Sample analyzing apparatus and method," which involves a primary searcher executing a primary search based on a sample mass spectrum. This method utilizes a primary library containing various standard mass spectra. When the judging unit determines that the search range needs to be expanded, a secondary searcher conducts a secondary search using a secondary library that includes predicted mass spectra derived from multiple molecular structures. The second patent is for a "Mass spectrometry method and information processing device." This invention allows for the selection of a composition estimation target peak from a sample's mass spectrum. It estimates a composition candidate based on the selected peak and calculates the distribution of a theoretical isotope peak corresponding to that candidate. The presence of adduct ions or desorbed ions in the sample is then determined by analyzing the mass differences between the measured and theoretical isotope peaks.
