Abstract: The present invention comprises novel methods of continuously monitoring the performance of an atmospheric pressure ionization (API) system. The methods of the invention allow for improved quality monitoring of the processes that leads to the formation of ions at atmospheric pressure. The methods of the invention further allow for continuously monitoring for the quality of the ion formation process in API without the addition of extraneous material (such as labelled compounds or control known compounds) to the system being monitored.

Abstract: A method for performing surface sampling of an analyte, includes the step of placing the analyte on a stage with a material in molar excess to the analyte, such that analyte-analyte interactions are prevented and the analyte can be solubilized for further analysis. The material can be a matrix material that is mixed with the analyte. The material can be provided on a sample support. The analyte can then be contacted with a solvent to extract the analyte for further processing, such as by electrospray mass spectrometry.

Abstract: A method for creating and delivering a personalized message, comprises the steps of: receiving, via an Internet web site, data from a client, including a selection of a celebrity and contact information for an intended recipient of the message; storing the data in a database; retrieving a message script from a database based on the selected celebrity; prompting the client to enter certain personal information about the intended recipient of the message; receiving the personal information about the intended recipient of the message; creating the personalized message from the message script and the personal information; and delivering the personalized message to the intended recipient using the contact information.

Abstract: A replaceable, electronically-isolated, MCP-based spectrometer detector cartridge with enhanced sensitivity is disclosed. A coating on the MCP that enhances the secondary electron emissivity characteristics of the MCP is selected from aluminum oxide (Al2O3), magnesium oxide (MgO), tin oxide (SnO2), quartz (SiO2), barium fluoride (BaF2), rubidium tin (Rb3Sn), beryllium oxide (BeO), diamond and combinations thereof A mass detector is electro-optically isolated the from a charge collector with a method of detecting a particle including accelerating the particle with a voltage, converting the particle into a multiplicity of electrons and converting the multiplicity of electrons into a multiplicity of photons. The photons then are converted back into electrons which are summed into a charge pulse. A detector also is provided.

Abstract: The present invention relates to an improved portable paint brush holder (or holster). The paint brush holder has means (such as a clip, loops, a stud and loop and the like) for attaching the brush holder to a belt of the painter and is a substantially rectangular container having a top opening to hold the paint brush in a upright position with the handle of the brush pointing up. The invention holds the wet paint brush securely, prevents paint drips and prevents drying of the paint on the brush. The invention also includes a kit comprising the portable paint brush holder which is detachably engaged to the belt of the painter and a clip for permanent attaching to the flat portion of the paint brush at the bristle-handle interface. The clip on the brush aids in securing the paint brush within the paint brush holder reservoir.
