Imaging Mass Spectrogram using Rotating Electric Fields Mass Spectrometer

Abstract

Imaging mass spectrometric technologies are innovating biological or medical scientific reorganizations using secondary ion mass spectrometry (SIMS) or matrix-assisted laser desorption ionization (MALDI) imaging [1]. This article briefly introduces“ an imaging mass spectrogram” by new principle double rotating electric fields (REFs) type mass spectrometer [2,3]. The imaging mass spectrogram indicates not spatial mass distributions but mass constitutions. Different masses draw annular ring patterns with respect to their existences and intensities on the same field of in the same time. The imaging mass spectrogram can be obtained by specific features of REFs type mass spectrometer; separates mass weight by filtering in high speed double REFs and draws annular ring patterns with direct continuous beam, simultaneously. The imaging mass spectrograms are mostly controlled by frequencies and intensities of REFs. The relationship with a specific frequency: f and a weight of single charged mass: m can be described by following equation [4]. 2 1 acc eV f L m =
