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
- Software as easy to use as 1-2-3
