A method for extracting an analyte from a sample matrix includes exposing the liner sorptive coating to the sample matrix ... 12/14/06 - 20060281191 - Method for monitoring organic deposits in papermaking A method for monitoring the deposition of organic deposits from a liquid or slurry in a papermaking process is disclosed. The method involves measuring the rate of deposition of organic deposits from the liquid or slurry of a papermaking process on to a quartz crystal microbalance having a top side ... 11/16/06 - 20060258017 - Apparatus and methods for use in concentration of gas and particle-laden gas flows For analysis of small quatities of target analytes in an environment, the gas flow can be delivered to a suitably fast analyzer and their concentration determined in a time period whose duration is dependent on the analyte, its concentration and the phase separation properties. A device having a sorbent bed ... 07/13/06 - 20060154378 - Method for measuring the leaching of encapsulated material into application media The invention provides a facile method for measuring the leaching of encapsulated active ingredient from application media. This is achieved by separating a container by a membrane permeable to encapsulated material, but not to capsules; pouring a solution of the application medium into a first part of the container; pouring ... 02/02/06 - 20060024840 - Method and apparatus for testing heavy oil production processes A method of testing oil extraction processes is shown. The method includes the steps of placing a sample to be tested in a sample holder which has a configurable temperature profile. The sample holder is then placed in a pressure vessel and the pressure in the pressure vessel is increased ... 02/02/06 - 20060024839 - Inorganic carbon removal Methods and related apparatus are disclosed for selective removal of inorganic carbon from a fluid sample using selective membranes to minimize the loss of volatile organic compounds from the fluid sample prior to analysis for determination of the total organic carbon contents of the sample. ... 09/22/05 - 20050208674 - Method for analyzing impurities The impurity analyzing method is for analyzing impurities that exist on a surface of a semiconductor wafer, which includes a step of bubbling a mixed solution including hydrofluoric acid and aqueous hydrogen peroxide or a mixed solution including hydrofluoric acid and aqueous ozone to generate a vapor including hydrofluoric acid ... 08/04/05 - 20050170524 - Impurity measuring method for ge substrates The present invention provides an impurity measuring method comprising the steps of dropping a drop of a first solution on the surface of a substrate to be measured, moving the drop dropped on the surface of the substrate so that the drop is kept in contact with the surface and ... 06/09/05 - 20050124074 - Method for identifying contaminants A method is provided for identifying contaminants on a surface. In one embodiment, an infrared beam is transmitted onto a sample. A first infrared absorbance of the sample is determined at a first wave number. A second infrared absorbance of the sample is determined at a second wave number. The ... ### FreshPatents.com Support |
