The combined APPI/APCI source components
The combined APPI/APCI source comprises the standard IonSABRE II probe
and a source enclosure with an APPI lamp drive incorporated.
The combined APPI/APCI source enclosure:
The UV lamp, which you ignite via a control in the MassLynx Tune window,
provides a constant photon output. You vary the intensity of incident
radiation upon the sample molecules by adjusting the distance between the
UV lamp and probe tip.
Caution: To prevent damage to the corona pin and lamp assembly,
ensure that the lamp assembly does not touch the corona pin when the
source enclosure door is closed.
