NEW YORK (GenomeWeb) – A team led by researchers at the Georgia Institute of Technology has developed a device that could increase the amount of sample introduced to mass spectrometers and significantly improve instrument sensitivity and signal-to-noise.

Called DRILL (dry ion localization and locomotion), the device links a mass spec system's electrospray ionization (ESI) component to the instrument's inlet using electrodes to manipulate the charged droplets generated via ESI and deliver them more effectively to the mass spectrometry.
