See the MassLynx 4.1 user documentation and online Help for more
information on installing and using MassLynx software.
OpenLynx™ and TargetLynx™ application managers are included as
standard software.

Instrument Console software

The Instrument Console is a software application with which you configure
settings, monitor performance, run diagnostic tests, and maintain the system
and its modules. The Instrument Console functions independently of
MassLynx software and does not recognize or control the data systems.
See the Instrument Console system online Help for details.

Ionization techniques and source probes

Electrospray ionization (ESI)

In electrospray ionization (ESI), a strong electrical charge is applied to the
eluent as it emerges from a nebulizer. The droplets that compose the resultant
aerosol undergo a reduction in size (solvent evaporation). As solvent continues
to evaporate, the charge density increases until the droplet surfaces eject ions
(ion evaporation). The ions can be singly or multiply charged.
The standard ESI probe accommodates eluent flow rates of up to 2 mL/min
making it suitable for LC applications in the range 100 µL/min to 2 mL/min.
See "ESI mode" on page 3-2
Combined electrospray ionization and atmospheric pressure
chemical ionization (ESCi)
Combined electrospray ionization and atmospheric pressure chemical
ionization (ESCi) is supplied as standard equipment on the mass
spectrometer. In ESCi, the standard ESI probe is used in conjunction with a
corona pin to allow alternating acquisition of ESI and APCI ionization data,
facilitating high throughput and wider compound coverage.
See "ESCi mode" on page 3-6
