1.4 Combined APPI/APCI source

Atmospheric pressure photoionization (APPI) uses photons generated by a discharge UV lamp
(~10.2 eV) to produce sample ions from vaporized LC eluent. Direct photoionization of the
sample molecule occurs when the photon energy exceeds the ionization potential of the sample
molecule.

Description
For flow injection or coupling to nanoACQUITY
systems. A pump regulates flow rate to as low
as 100 nL/min.
Uses metal-coated glass capillaries, permitting
the lowest flow rates. Usable for one sample
only, after which you must discard them.
