Electrospray (ESI) Source

Electrospray ionization (ESI) is a mainstay of LC/MS that can be used to analyze large and small analytes. The Agilent electrospray ion source uses patented orthogonal nebulization and a heated counterflow drying gas system to achieve excellent sensitivity and robust, reliable performance. A dual-nebulizer ESI source is available for TOF and Q-TOF instruments, with the second nebulizer dedicated to the continuous introduction of a reference mass to ensure superior mass accuracy.

LC/MS Ion Sources

Features

Well suited for analysis of biological macromolecules such as proteins and peptides, as well as for smaller, more polar molecules
Capable of generating multiply charged ions while operating at relatively low temperatures
Concentration-sensitive technique enables use of more concentrated samples for improved sensitivity, allowing lower flow rates in sample-limited applications
Available for standard flow, capillary flow, and nanoflow regimes
