Method and Device for Microparticle Assay Fluorescence Intensity Reference Intraplex

Номер: US20120053085A1

Автор: Brian P. Hanley

Принадлежит: Individual

A method for making suspended microarray readings from a single sample more reliably accurate. It can be applied to any assay system that uses discrete particles coupled with an assay. Most of these are fluidic systems that read the assay result using flow cytometry. However, other methods such as the distribution of tiny assay devices coupled with miniature transponders, where the sampling is of the environment, can also make use of this method. This invention combines a reference set of signal levels on particles with separately identified assays of one sample. By elimination of outliers, averaging, taking ratios of averages, and then taking ratios of assay signal levels against the reference set this method makes possible highly reliable diagnostics. When used standalone, the method uses different signal intensities to better calibrate an instrument. This method compensates for multiple sources of errors that can occur in this type of assay system.

Process and Apparatus for Steam-Methane Reforming

Автор: Clive Derek Lee-Tuffnell, Ian Frederick Zimmerman, Jason Andrew Maude, John William Stairmand, Michael Joseph Bowe

Принадлежит: Clive Derek Lee-Tuffnell, Ian Frederick Zimmerman, Jason Andrew Maude, John William Stairmand, Michael Joseph Bowe

Methane reacts with steam generating carbon monoxide and hydrogen in a first catalytic reactor; the resulting gas mixture undergoes Fischer-Tropsch synthesis in a second catalytic reactor. In the steam/methane reforming, the gas mixture passes through a narrow channel having mean and exit temperatures both in the range of 750° C. to 900° C., residence time less than 0.5 second, and the channel containing a catalyst, so that only reactions having comparatively rapid kinetics will occur. Heat is provided by combustion of methane in adjacent channels. The ratio of steam to methane may be about 1.5. Almost all methane will undergo the reforming reaction, almost entirely forming carbon monoxide. After Fischer-Tropsch synthesis, the remaining hydrogen may be fed back to the combustion channels. The steam for the reforming step may be generated from water generated by the chemical reactions, by condensing products from Fischer-Tropsch synthesis and by condensing water vapor generated in combustion.

The development of miniaturized chromatographic systems localized within individual polymer microspheres and their incorporation into a bead-based cross-reactive sensor array platform is described herein. The integrated chromatographic and detection concept is based on the creation of distinct functional layers within the microspheres. In this first example of the new methodology, complexing ligands have been selectively immobilized to create “separation” layers harboring an affinity for various analytes. Information concerning the identities and concentrations of analytes may be drawn from the temporal properties of the beads' optical responses, Varying the nature of the ligand in the separation shell yields a collection of cross-reactive sensing elements well suited for use in array-based micro-total-analysis systems.

Dispersed Bubble Reactor For Enhanced Gas-Liquid-Solids Contact And Mass Transfer

Номер: US20120216680A1

Автор: Alexander Bonsu, Guohai Liu, Pannalal Vimalchand, Wanwang Peng

Принадлежит: Southern Co

An apparatus to promote gas-liquid contact and facilitate enhanced mass transfer. The dispersed bubble reactor (DBR) operates in the dispersed bubble flow regime to selectively absorb gas phase constituents into the liquid phase. The dispersion is achieved by shearing the large inlet gas bubbles into fine bubbles with circulating liquid and additional pumped liquid solvent when necessary. The DBR is capable of handling precipitates that may form during absorption or fine catalysts that may be necessary to promote liquid phase reactions. The DBR can be configured with multistage counter current flow sections by inserting concentric cylindrical sections into the riser to facilitate annular flow. While the DBR can absorb CO 2 in liquid solvents that may lead to precipitates at high loadings, it is equally capable of handling many different types of chemical processes involving solids (precipitates/catalysts) along with gas and liquid phases.

The systems utilize at least one Fischer-Tropsch reactor containing hybrid Fischer-Tropsch catalyst with cooling and separation of reactor effluent following each reactor. The low cloud point indicates that the amount of wax in the hydrocarbon products is minimized relative to conventional Fischer-Tropsch conversion. Accordingly, more economical systems can be built and operated because equipment associated with wax removal or wax treatment can be reduced or eliminated.
