Mass spectrometry sampling under ambient conditions with desorption electrospray ionization.
A new method of desorption ionization is described and applied to the ionization of various compounds, including peptides and proteins present on metal, polymer, and mineral surfaces. Desorption electrospray ionization (DESI) is carried out by directing electrosprayed charged droplets and ions of solvent onto the surface to be analyzed. The impact of the charged particles on the surface produce...
متن کاملAdvances in technologies and techniques for ambient intelligence
Human activity is attracting a lot of research activity in several fields including the use of wireless sensors, positioning technologies and techniques, embedded computing, remote sensing and energy management among others. There are a number of applications where the results of those investigations can be applied, including ambient intelligence to support human activity, particularly the elde...
متن کاملPrinciples of electrospray ionization.
Electrospray ionization is today the most widely used ionization technique in chemical and biochemical analysis. Interfaced with a mass spectrometer it allows the investigation of the molecular composition of liquid samples. With electrospray a large variety of chemical substances can be ionized. There is no limitation in mass which thus enables even the investigation of large noncovalent prote...

A new method of desorption ionization is described and applied to the ionization of various compounds, including peptides and proteins present on metal, polymer, and mineral surfaces. Desorption electrospray ionization (DESI) is carried out by directing electrosprayed charged droplets and ions of solvent onto the surface to be analyzed. The resulting mass spectra are similar to normal ESI mass ...
متن کاملAmbient molecular imaging by laser ablation electrospray ionization mass spectrometry with ion mobility separation
Mass spectrometry imaging (MSI) by laser ablation electrospray ionization (LAESI) enables the lateral mapping of molecular distributions in untreated biological tissues. However, direct sampling and ionization by LAESI–MSI limits the differentiation of isobaric ions (e.g., structural isomers) in a complex sample. Ionmobility separation (IMS) of LAESI-generated species is sufficiently fast to be...
