Multiplexed operation of an ultrasonic droplet ejector

What is it about?

A dual-sample ultrasonic droplet ejector array is developed for use as a soft-ionization ion source for multiplexed mass spectrometry MS. Such a multiplexed ion source aims to reduce MS analysis time for multiple analyte streams, as well as allow for the synchronized ejection of the samples and an internal standard for quantitative results and mass calibration.
