3-18 Configuring the LockSpray Source
Configuring for ESCi mode
To operate in ESCi mode, you must fit an ESI probe and corona pin to the
LockSpray source enclosure.
The system, with the ESI probe installed and corona discharge pin fitted, can
alternate between ESI and ESCi modes, facilitating data acquisition in ESI
and ESCi modes in parallel. For more information on using dual ESI and
ESCi modes, see the Xevo G2 QTof system online Help.
See
“Installing the ESI probe” on page 3-2 , “Installing the corona pin in the
source” on page 5-11 , and “Combined electrospray and atmospheric pressure
chemical ionization (ESCi)” on page 1-9 .
Optimizing the ESI probe for ESCi operation
See the mass spectrometer’s online Help for details on how to optimize the ESI
probe for ESCi operation.
