A stoichiometry of glutathione and common amino acids were mixed to reach the equilibrium, and then the mixed solution was investigated by electrospray ionization mass spectrometry (ESI–MS). The ...

Electrospray ionization mass spectrometry (ESI-MS) has emerged as a pivotal analytical tool, enabling the gentle conversion of analytes in solution into gas-phase ions while minimising fragmentation.

Mass spectrometry (MS) is already perhaps the most popular analytical chemistry tool in drug discovery and development. Its use is ubiquitous in bioanalytical laboratories for drug and metabolite ...

In electrospray ionization (ESI), an electric potential is applied to a solution inside a capillary, producing a strong electric field at the spray capillary tip. That leads to the expulsion of an ...

Electrospray ionization (ESI) is best known as a way to introduce chemical compounds and mixtures into mass spectrometers. The machines apply a voltage to a stream of liquid containing a sample, ...

WEST LAFAYETTE, Ind. — Researchers at Purdue University have used a new technique to rapidly detect and precisely identify bacteria, including dangerous E. coli, without time-consuming treatments ...

Researchers have developed a novel technology that allows the distribution of components within a single cell to be accurately detected and visualized. Positioning a t-SPESI (tapping-mode scanning ...

What are the ionization techniques for mass spectrometry? Mass spectrometry (MS) plays a vital role in many aspects of our lives, from diagnosing illness and detecting food contaminants to fighting ...

The authors developed a method to accurately measure the average molecular weight of large poly(ethylene glycols) (PEGs) using ion-mobility time-of-flight mass ...
