|20130139574||Devices for heating and cooling a capillary liquid chromatographic system - Devices for heating and cooling chromatographic columns, transfer tubing, fittings and accessories and can also be placed next to the mass spectrometer's inlet region are disclosed. These devices have the advantage of allowing the user to dramatically reduce the post-column dead-volume while using the heating or cooling devices, a necessity for low-flowrate liquid chromatography. These devices also do not require the user to heat or cool the entire column with fittings to achieve optimized benefits for chromatography.||06-06-2013|
|20090250607||METHOD AND APPARATUS TO INCREASE THROUGHPUT OF LIQUID CHROMATOGRAPHY-MASS SPECTROMETRY - An apparatus according to the present invention includes a plurality of sample spraying devices, each of which connects to an LC column. The apparatus includes an electrical circuit that can turn a high voltage between 1 and 5 KV on and off on the time-scale of nanoseconds to milliseconds. The circuit is controlled by a computer program which applies the high voltage to each spray device in a Hadamard sequence. The spray devices are positioned aiming at the mass spectrometer inlet. The preferred configuration of arrangements for the spray devices are in a circle or an arc of a circle around the inlet of a mass spectrometer.||10-08-2009|
|20090095057||INTEGRATED MICROFLUIDIC NOZZLE DEVICE FOR CHROMATOGRAPHIC SAMPLE PREPARATION FOR MASS SPECTROMETRY APPLICATIONS - In accordance with one aspect of the present invention, a low-cost injection-molded plastic microfluidic device that performs the multiplexing of affinity or chromatographic sample cleanup and enrichment methods and the detection by nanospray mass spectrometry of analytes such as biomarkers in a single package to conserve sample, and processes body fluids with HPLC grade and even next-generation chromatographic resins such as nanoparticles to maximize the sensitivity of the detection.||04-16-2009|
|20080203198||APPARATUS AND METHOD FOR CONTROLLING AN ELECTROSTATICALLY INDUCED LIQUID SPRAY - A method for controlling an electrostatically induced liquid spray includes the steps of: (1) generating a liquid spray from a liquid sample with an electrostatic spray nozzle device using an applied electric field, wherein at least a nozzle portion of the spray device is formed of an insulating material; (2) sensing a current of the liquid spray with a spray current sensing means placed in relation to the spray device; (3) comparing the sensed current of the liquid spray with a pre-selected current value, with a difference between the two representing a control signal; and (4) varying the applied electric field using a computer-controlled positioning mechanism that moves the spray device relative to an inlet of the object that receives the liquid spray and acts as a counter-electrode.||08-28-2008|
