Abstract: An ion manipulation device and systems and methods for controlling the ion manipulation device. The ion manipulation device includes a pair of counter-facing surfaces and a plurality of electrodes arranged in one or more linear array on each of the counter-facing surfaces. At least one RF power source is coupled to the electrodes and configured to apply an RF potential to the electrodes to create an electric field that inhibits charged particles from approaching the counter-facing surfaces. At least one DC power source is coupled to the electrodes and configured to apply a DC potential to affect the movement of ions between the counter-facing surfaces in a direction parallel to the counter-facing surfaces. The DC potential and the RF potential are applied to the electrodes simultaneously.

Abstract: The present invention relates to a method for the generation of a Sitemap XML file. The method comprises retrieving input parameter values and determining at least one target entity (an online retail store) within a target environment (a retailer) for which a search engine sitemap definition page will be generated and rendering the sitemap definition page for the determined target entity. The rendered content being further evaluated and ordered according to predetermined priority algorithms. The method further comprises outputting the rendered sitemap definition page, where if the output sitemap definition page exceeds a predetermined size, the output sitemap definition page is divided into smaller segments and an index file is generated and associated with the segmented output sitemap definition page files. Caching functionality (to enhance operational performance) and access control functionality (for controlling the rendering of sitemaps) is further provided within aspects of the present invention.

Abstract: A method and apparatus for multiplexed data acquisition for gas-phase ion mobility coupled with mass spectrometry is described. Ion packets are injected into an ion mobility drift chamber at a rate faster than the ion mobility separation arrival time distribution. The convoluted arrival time distributions thus generated are deconvoluted by a mass spectrometer and post-processing algorithms.

Abstract: The present invention is directed to a novel arrangement of optical devices for the rapid patterning of laser profiles used for desorption and/or ionization sources in analytical mass spectrometry. Specifically, the new optical arrangement provides for a user-defined laser pattern at the sample target that can be quickly changed (on a microsecond timescale) to different dimensions (or shapes) for subsequent laser firings.

Abstract: A method and device for the gas-phase separation of ionic biomolecules including peptide, and protein or inorganic cluster ions or nanoparticles by ion mobility and for depositing them intact on a surface in a spatially addressable manner is described. The surface onto which the proteins are deposited can be modified for the purpose of constructing microarrays of biologically relevant materials or for promoting the growth of highly ordered protein crystals.

Abstract: A simple, relatively low-cost direct injection high efficiency nebulizer (DIHEN) is suitable for argon inductively coupled plasma (Ar ICP) spectrometry. The DIHEN may be operated at solution uptake rates of 1-100 .mu.L/min. Analytical performance indices for the DIHEN and fundamental characteristics of the aerosol produced are obtained using an ICP mass spectrometer (ICPMS) and a 2-dimensional phase Doppler particle analyzer (2D PDPA), respectively. Results are compared to those obtained with a conventional crossflow pneumatic nebulizer (PN), equipped with a Scott-type spray chamber. Droplet sizes and velocities produced with the DIHEN are smaller than those reported for the direct injection nebulizer (DIN). The DIHEN offers optimal sensitivity at low injector gas flow rates (approx. 0.25 L/min) and high RF power (approx. 1.5 kW). For the 17 elements tested, detection limits (ppt) and sensitivities achieved with the DIHEN (at 85 .mu.
