Plastic nozzle emitters
The patented polypropylene plastic nozzle has a 20 um i.d. and a 50 um o.d.. It forms a liquid tight junction with a 360 um o.d. fused silica capillary without any fitting and with virtually no dead volume. It is ideal as a non-clogging, removable and reusable spray emitter for a fused silica capillary column with a flat cut end that is tapered. The extremely nonactive plastic surface makes clogging unlikely even when complex materials such as a diluted unfiltered serum or a fermentation broth is sprayed.
