20160079051 | INTEGRATED NANOSPRAY SYSTEM - Integrated nanospray ionization package, comprising a nanospray emitter, a push button carriage with button element projecting through a bore in said package, an integral high voltage contact pin, a bore in said package for reversible protrusion of the nanospray emitter, a push-and-retract spring mechanism in which the range of forward motion of the emitter is not dependent on range of travel of the said button, and then upon actuation of said button element and spring element for retraction of said nanospray emitter, said nanospray emitter is pushed forward to establish electrical contact, and upon release of said button retracts and breaks the electrical contact. | 03-17-2016 |
20120153143 | ELECTROSPRAY AND NANOSPRAY IONIZATION OF DISCRETE SAMPLES IN DROPLET FORMAT - Droplets or plugs within multiphase microfluidic systems have rapidly gained interest as a way to manipulate samples and chemical reactions on the femtoliter to microliter scale. Chemical analysis of the plugs remains a challenge. It has been discovered that nanoliter plugs of sample separated by air or oil can be analyzed by electrospray ionization mass spectrometry when pumped directly into a fused silica nanospray emitter nozzle. Using leu-enkephalin in methanol and 1% acetic acid in water (50:50 v:v) as a model sample, we found carry-over between plugs was <0.1% and relative standard deviation of signal for a series of plugs was 3%. Detection limits were 1 nM. Sample analysis rates of 0.8 Hz were achieved by pumping 13 nL samples separated by 3 mm long air gaps in a 75 μm inner diameter tube. Analysis rates were limited by the scan time of the ion trap mass spectrometer. The system provides a robust, rapid, and information-rich method for chemical analysis of sample in segmented flow systems. | 06-21-2012 |
