Waters XEVO APPI


The XEVO™ APCI / APPI probe introduces samples into the ion source, incorporating 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.

Product Benefits/Features:
Together, APPI and APCI provide you with the ability to comprehensively analyze low polarity and non-polar compounds in a single experiment.
