CESI 8000 Plus ESI-MS System

CESI 8000 Plus ESI-MS High Performance Systems Overview

See what you've been missing with CESI-MS

Experience the revolutionary ESI-MS approach to discovering previously undetectable characteristics from the minutest amount of precious samples, faster than ever before. Whether using as a standalone capillary electrophoresis instrument or in conjunction with the power of mass spectrometry, the CESI 8000 Plus system allows you to concentrate on your science rather than technology. You’ve worked hard to get your sample this far. Get the most from that precious material and hunt down the hidden information you couldn’t see before:

• Intact mAb charge variants with online MS detection
• Proteoforms and peptide PTMs such as those with multiple phosphorylation sites
• Challenging charged and polar metabolites/degradation products such as anionic and/or hydrophilic analytes
• Isobaric metabolites and glycans not resolved by traditional techniques
• Protein conformation and quantitation

 

Key Features

Zero dead volume

Single continuous separation capillary is contained within the OptiMS cartridge

Multi-detection capability

In stand-alone CE mode, UV/VIS, PDA, or LIF detection can be selected

Multiple injections from precious samples

Sample analysis from as little as 5 μL

 

Go beyond the possibilities

CE-MS: More info, less sample

Learn why capillary electrophoresis - mass spectrometry (CE-MS) is an attractive microscale analytical technique for addressing biological questions inherently dealing with low amounts of material.

Isobaric compounds

Simplify the analysis of isobaric compounds inadequately resolved with current methods.

Native conditions

Study the molecular interactions and structure of your proteins and peptides under native conditions.

 

See more than ever before

Expanded coverage allows you to see more than ever before.

Expand the coverage

Reveal hydrophilic charged and polar compounds and increase sensitivity in your metabolome and glycome analysis, not possible with LC methods.

Uncover new PTMs

Confidently quantify and characterize proteoform and peptide PTMs, such as those with multiple phosphorylation and glycosylation sites.

Separate isomers

Resolve isomers – unseeable with traditional LC-MS methods.

 

More dynamic, efficient processes

CESI-MS allows for a more robust system with ultra-low-flow < 10 nL/min, into the mass spectrometer resulting an overall increase in ionization efficiency.

Minute sample consumption

Samples are often limited in quantity. CESI-MS has nL sample consumption, leaving most of the material available for analysis by orthogonal techniques.

Streamline your workflow

Use the same method and reagents for multi-level characterization of protein therapeutics. Switch between pos and neg ion modes without changing setup.

Frustration free

Open tube technology eliminates frustrations common with nanoscale techniques. No more minimizing dead volumes, or dealing with carryover and clogs.
