THE mass spectrometer is often used for the measurement of the appearance potentials of ions produced by electron bombardment of gaseous molecules. For this purpose, two gases are admitted to the ...

Ionization and coupling are two different sub-disciplines in the field of mass spectrometry. Ambient ionization allows direct, high-throughput, surface study of native samples. And for the study of a ...

EC-MS can be used to analyze a wide range of biological reaction. In this technique, electrochemistry is used to determine the concentration or chemical reactivity of a substance by measuring either ...

The ability to measure mass to charge ratio of the ions in mass spectrum is the most important feature of the high-resolution mass spectrometers. An analyte's identification can be progressed further ...

MALDI remains a powerful tool for analyzing large biomolecules with minimal fragmentation. In this process, peptides or proteins are co-crystallized with a matrix on a metal plate. A laser pulse ...

In this interview, AZoM talks to Ed Sprake, Principal Product Manager at Waters, about the work Waters do with ambient ionization in mass spectrometry and the potential that this innovation has.
