Introduction

Erina Shimizu is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of mass spectrometry, holding a total of 5 patents. Her innovative work has advanced the capabilities of analytical techniques used in various scientific applications.

Latest Patents

One of her latest patents involves an inductively coupled plasma mass spectrometry (ICP-MS) system with improved signal-to-noise and signal-to-background ratios. In this system, ions are transmitted into a collision/reaction cell. A DC potential is applied at the exit of the cell at a first magnitude to generate a DC potential barrier effective in preventing the ions from exiting the cell. The DC potential barrier is maintained during a confinement period to perform an interaction. After this period, analyte ions or product ions are transmitted to a mass spectrometer by switching the exit DC potential to a second magnitude, allowing the ions to pass through the cell exit as a pulse. The analyte ions or product ions are then counted during a measurement period. The interaction may involve ion-molecule reactions or ion-molecule collisions.
