1. A system for identifying a first sample in an analysis sequence of one or more analysis samples to be analyzed, comprising:
an acoustic droplet ejection device (ADE) operative to eject a sample from one or more sample wells;
an open port interface operative to receive the ejected sample and transport the received sample to a mass analyzer;
the mass analyzer operative to perform mass analysis on the sample to produce representative mass peaks; and
a controller, comprising at least a processor, operative to direct the ADE to eject an identifiable sequence of one or more ejections from the sample wells prior to initiating an analysis sequence of ejections for the one or more analysis samples.
