Title:
質量分析計内へとイオンを効率的に搬送するための方法および装置
Document Type and Number:
Japanese Patent JP4520979
Kind Code:
B2
Abstract:
An apparatus and a method which produce a pulse of ions, generate a transient electric field correlated in time with a duration of the pulse of ions, receive the pulse of ions into the transient electric field, and collect the ions from an ion drift region of the transient electric field into a gas dynamic flow region of the mass analyzer. As such, an apparatus for transferring ions into a mass analyzer includes an ion source configured to generate the pulse of ions, a transient electric field device configured to receive the pulse of ions and generate the transient electric field, and an ion collector configured to collect the ions from the ion drift region and transfer the ions into the mass analyzer.
