Unleash the power of CE separation for the best in mass spectrometry detection.
The OptiMS cartridge assembly consists of a separation capillary terminating in the porous sprayer, a conductive liquid capillary, circulating liquid cooling, and sprayer housing. Conductive fluid is delivered automatically from a system vial that completes the CE circuit.
This capillary is housed in a protective cartridge that allows easy transfer and routine use in a rugged and robust manner. With the CESI 8000 system, the cartridge simply clicks into place creating an easy-touse plug-and-spray set up for your mass spectrometry.
Located within a protective housing, the CESI 8000’s sprayer combines an intrinsically low-flow CE separation with electrospray ionization (ESI) within a single, simple device that has no liquid junction or dead volume.
Capillary’s distal end is porous to allow ion flow
Electrical contact for the CE is achieved through an ESI needle filled with conductive fluid
ESI’s electrical contact is achieved through the protruding capillary tip
Low flow at the tip terminus instantly generates a fine spray when ESI voltage is applied
All electrochemistry associated with electrolysis of water is hereby decoupled from the spray
Capillary inlet and exit are of the same dimension, reducing the clogging often associated with nanoscale techniques
ESI is generated at lower voltages, which reduces the risks of oxidation artifacts
Swift and simple “plug-and-spray” design increases operational efficiency
Automated sample handling from microvials
Simple interfacing with automatic triggering of MS data collection
Easy switching between liquid chromatography (LC) and CESI-MS
