The Atmospheric Pressure Photoionization (APPI) source, in conjunction with Atmospheric Pressure Chemical Ionization (APCI) allows independent APPI and APCI experiments with the ability to acquire APPI and APCI data in the same analysis.
The IonSABRE APCI probe introduces samples into the ion source, which incorporates a Syagen Technologies 10.6 ev krypton discharge UV lamp. The lamp emits photons that excite analyte molecules and subsequently produce ions through electron ejection. In this process, sample molecules are preferentially ionized when the photon energy exceeds their ionization potential, but is lower than the ionization potential of the surrounding vaporized LC eluent.
Together, APPI and APCI provide you with the ability to comprehensively analyze low polarity and non-polar compounds in a single experiment
The APPI/APCI Dual Ionization Source is available for the following MS instruments:
SQ Detector 2, Xevo TQD
Xevo TQ MS, Xevo TQ-S, Xevo TQ-S micro
Xevo QTof MS, Xevo G2 QTof, Xevo G2-S QTof, Xevo G2-XS QTof
Xevo G2 Tof, Xevo G2-S Tof, Xevo G2-XS Tof
(MALDI) SYNAPT G2 MS/HDMS, (MALDI) SYNAPT G2-S MS/HDMS, (MALDI) SYNAPT G2-Si MS/HDMS
The source includes an IonSABRE APCI probe, corona pin, krypton discharge lamp and control unit, instrument interface/source enclosure assembly, spare parts kit and user guide. The source requires installation and operation training by a Waters Field Service Engineer.
