A mass spectrometer analyzes ... for efficient ionization. ESI is the most common form of ionization used for MS. 3 It employs voltage to convert a flow of liquid to generate an electrospray. A ...

Users unfamiliar with Mass Spectrometry are advised to consult with Xiao Feng about what might be the most suitable method to solve their problem. 1. Some guidelines for methods to ionize samples: a.

including electron ionization (EI), electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), and atmospheric pressure photo ionization (APPI). Tandem mass spectrometry (MS/MS or ...

mainly used for small molecule mass analysis and hydrogen/deuterium exchange-mass spectrometry (HDX-MS). It has an electrospray ionization (ESI) interface, meaning that analytes need to be dissolved ...
