Development and Application of an Ion Gate Driving Power Supply for Inverse Ion Mobility Spectrometry

Zhipu Xuebao
Ion mobility spectrometry (IMS) is a trace detection technique. It realizes rapid separation and detection of ions by capitalizing on the disparities in the mobility velocities of ions in an electric field under atmospheric pressure.

ZnCl2 Post‐Treatment Enables High‐Efficiency Violet CsPbCl3 Quantum Dot LEDs

Advanced Optical Materials, EarlyView.
Schematic illustration of ZnCl2 post‐treatment–induced doping in CsPbCl3 quantum dots (QDs). ABSTRACT Perovskite light‐emitting diodes (LEDs) have achieved external quantum efficiencies (EQEs) above 20% in the red, green, and blue spectral regions, yet their efficiency rapidly declines as the bandgap widens for shorter‐wavelength emission.

On-line analysis of coffee roasting with ion mobility spectrometry–mass spectrometry (IMS–MS)

International Journal of Mass Spectrometry, 2018
Online analysis of coffee roasting was performed using ion mobility spectrometry–mass spectrometry (IMS-MS) with corona discharge ionization. This is the first time that formation of volatile organic compounds (VOCs) during coffee roasting was monitored not only in positive but also in negative ion mode, and not only with mass spectrometry, but also ...

Mass spectrometry imaging of N‐linked glycans: Fundamentals and recent advances

Mass Spectrometry Reviews, EarlyView.
Abstract With implications in several medical conditions, N‐linked glycosylation is one of the most important posttranslation modifications present in all living organisms. Due to their nontemplate synthesis, glycan structures are extraordinarily complex and require multiple analytical techniques for complete structural elucidation.
