Book Synopsis Sub-micron Particle Sampler Apparatus by :
Download or read book Sub-micron Particle Sampler Apparatus written by and published by . This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Apparatus and method steps for collecting sub-micron sized particles include a collection chamber and cryogenic cooling. The cooling is accomplished by coil tubing carrying nitrogen in liquid form, with the liquid nitrogen changing to the gas phase before exiting from the collection chamber in the tubing. Standard filters are used to filter out particles of diameter greater than or equal to 0.3 microns; however the present invention is used to trap particles of less than 0.3 micron in diameter. A blower draws air to said collection chamber through a filter which filters particles with diameters greater than or equal to 0.3 micron. The air is then cryogenically cooled so that moisture and sub-micron sized particles in the air condense into ice on the coil. The coil is then heated so that the ice melts, and the liquid is then drawn off and passed through a Buchner funnel where the liquid is passed through a Nuclepore membrane. A vacuum draws the liquid through the Nuclepore membrane, with the Nuclepore membrane trapping sub-micron sized particles therein. The Nuclepore membrane is then covered on its top and bottom surfaces with sheets of Mylar. RTM. and the assembly is then crushed into a pellet. This effectively traps the sub-micron sized particles for later analysis.
Book Synopsis Portable Sample Preparation and Analysis System for Micron and Sub-micron Particle Characterization Using Light Scattering and Absorption Spectroscopy by :
Download or read book Portable Sample Preparation and Analysis System for Micron and Sub-micron Particle Characterization Using Light Scattering and Absorption Spectroscopy written by and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: There is provided a method and device for remote sampling, preparation and optical interrogation of a sample using light scattering and light absorption methods. The portable device is a filtration-based device that removes interfering background particle material from the sample matrix by segregating or filtering the chosen analyte from the sample solution or matrix while allowing the interfering background particles to be pumped out of the device. The segregated analyte is then suspended in a diluent for analysis. The device is capable of calculating an initial concentration of the analyte, as well as diluting the analyte such that reliable optical measurements can be made. Suitable analytes include cells, microorganisms, bioparticles, pathogens and diseases. Sample matrixes include biological fluids such as blood and urine, as well as environmental samples including waste water.

Book Synopsis BALLOON-BORNE PARTICULATE FRACTIONATOR. by : H. W. Zeller
Download or read book BALLOON-BORNE PARTICULATE FRACTIONATOR. written by H. W. Zeller and published by . This book was released on 1960 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes work done by General Mills Mechanical Division in the design, fabrication and testing of a balloon-borne dust sampling system. The purpose of the sampling system is to collect radioactive dust and meteoritic particles in the micron and submicron size ranges. The system samples the air continuously as the balloon rises in the altitude range from 30,000 to 100,000 feet. The particle collection apparatus consists of four units with each unit designed to be used over a given altitude range. Each unit employs two impactors and a filter in a series arrangement. The impactors collect the atmospheric dust on round slides and are designed for given particle size ranges.
