POLYMER-BASED ELECTROSPRAY NOZZLE FOR MASS SPECTROMETRY

摘要

A MEMS device with an overhanging "polymer" capillary (20) provides vital and significant improvements in interfacing a MEMS electrospray nozzle (50) to an MS inlet or other macroscopic instrumentation. The fabrication methodology associated therewith is easily expanded to include built-in micro particle filters (71) and centimeter long serpentine micro channels (75) provided on-chip (19) and fabricated using a low temperature process.
