1-8 Waters TQ Detector
Atmospheric pressure chemical ionization
A dedicated, high-performance, atmospheric-pressure, chemical ionization
(APCI) probe is offered as an option. See Chapter 4, “Optional APCI Mode of
Operation”, for full details.
Atmospheric pressure photoionization
Atmospheric pressure photoionization (APPI) is offered as an option. It uses
photons generated by a krypton-discharge ultraviolet (UV) lamp (10.2 eV) to
produce sample ions from vaporized LC eluent.
