SUPER SESI, general description
Principle of operation
A nano-electrospray creates the ions that are used to charge the molecules of interest, which
are introduced though the sample line. The molecules of interest and the charging ions react at
ambient pressure to form analyte ions. These ions are then passed to the mass spectrometer
for analysis.
Ions are not fragmented, enabling for MS-MS analysis and reliable analyte identification.
An accelerated flow is used to radially confine the ions and focus them to the mass inlet, without
perturbing the ionization region. The fast response of the ionizer enables kinetic studies, which
eases to identify specific responses to controlled stimuli, and to differentiate confounding
variables from real discoveries.
SUPER SESI incorporates all the components and controls in one single unit. It is ready to connect
with the MS and start analyzing. Very little sample preparation and virtually no laboratory
consumables are required. SUPER SESI is designed to easily replace the capillary when required.
A nano-ampere meter is used to monitor the stability of the electrospray.
Intended use
SUPER SESI is designed to be coupled with a mass spectrometer and to be used by trained
personnel in a laboratory environment. The purpose of SUPER SESI is to enable analysis of VOCs
at trace concentration. It is not intended for use with concentration of substances that could be
harmful or corrosive.
CAUTION
The safety of this equipment could be compromised if it is not used in the
manner specified in this manual.
