Properties of a new Ion Funnel
Atmospheric Pressure Ion (API) sources, inductively coupled plasma, corona discharges, lasers, electrospray and ion spray sources, are widely used in mass spectrometry. These sources create ions at atmospheric pressure. To analyze the masses of ions, they are introduced into a mass analyzer that is generally maintained at high vacuum. A differential pumping system involving several stages is co...
متن کاملRectangular Ion Funnel: A New Ion Funnel Interface for Structures for Lossless Ion Manipulations
Structures for lossless ion manipulations (SLIM) have recently demonstrated the ability for near lossless ion focusing, transfer, and trapping in subatmospheric pressure regions. While lossless ion manipulations are advantageously applied to the applications of ion mobility separations and gas phase reactions, ion introduction through ring electrode ion funnels or more conventional ion optics t...
متن کاملEar Douche in Plague Deliriium
To the Editor of "The Indian Medical Gazette." Sir,?Every one must have noted the feeling of warmth produced by merely closing the external auditory meatus in cold weather. Inferring that circulation even in such a small area as the auditory canal must be affecting the general circulation and particularly the cerebral one, ear douche with cold water at ordinary temperature was tried in delirium...
متن کاملBeyond ‘Funnel’ and ‘Fireworks’: ‘Water Ribbed Balloon’ as a New Metaphorical Approach to Innovation-in-Practice
Product innovation success has very much to do with the development of models ormetaphors that are able to guide actors. One can observe two traditions in thisregard: rational and non-rational models. Apparently in the former the model, suchas “development funnel”, is regarded as a mechanism and rigid applicable, picturinginnovation as an orderly, goal-oriented, value-neutral, and systematic pr...
