This listing is for one Waters IonKey MS Microflow UPLC Ion Source W/ 150 µm iKey. Source was recently removed from service during large lab closure. Set comes as pictured with one iKey and a second adapter plate / camera set that may or may not go with this source. We believe this works with the Waters Xevo G2-XS QTof, Synapt G2-Si, Xevo TQ-S, and Xevo TQ-S Micro spectrometers. Please do your own research to make sure this will work for your needs / instrument, as we are selling it as-is, with no returns.
