CESI 8000 Plus system by SCIEX

Extending the reach of your mass spectrometer.

Mass spectrometry (MS) has become an indispensable technology for the analysis of compounds of biological interest. Our improvements in assay sensitivity and reduction in ion suppression reveal new information that is critical to your research, whether you’re characterizing a therapeutic protein, identifying the proteins that make up a specific proteome, analyzing post-transitional modifications, or studying a metabolomic fingerprint. We developed a new front-end separation and ionization technology called CESI, which combines the high efficiency and ultra-low flow of capillary electrophoresis (CE) with an integrated electrospray ionization source. This optimization of electrospray ionization (ESI) into the nanoflow region has been shown to greatly improve assay sensitivity and reduce ion suppression.
