Abstract

Provided herein are batch methods and devices for enriching trace quantities of impurities in gaseous mixtures, such as hydrogen fuel. The methods and devices rely on concentrating impurities using hydrogen transport membranes wherein the time period for concentrating the sample is calculated on the basis of optimized membrane characteristics, comprising its thickness and permeance, with optimization of temperature, and wherein the enrichment of trace impurities is proportional to the pressure ratio P.sub.hi/P.sub.lo and the volume ratio V.sub.1/V.sub.2, with following detection of the impurities using commonly-available detection methods.

Early Recovery of Salmonella from Food Using a 6-Hour Non-selective Pre-enrichment and Reformulation of Tetrathionate Broth

Journal Article Daiquigan, Ninalynn ; Grim, Christopher J. ; White, James R. ; ... - Frontiers in Microbiology

Culture based methods are commonly employed to detect pathogens in food and environmental samples. These methods are time consuming and complex, requiring multiple non-selective and selective enrichment broths, and usually take at least 1 week to recover and identify pathogens. Improving pathogen detection in foods is a primary goal for regulatory agencies and industry. Salmonella detection in food relies on a series of culture steps in broth formulations optimized to resuscitate Salmonella and reduce the abundance of competitive bacteria. Examples of non-selective pre-enrichment broths used to isolate Salmonella from food include Lactose, Universal Pre-enrichment, BPW, and Trypticase Soy broths. Tetrathionatemore »« less

Carbon nanotubes (2,5-dihydroxybenzoyl hydrazine) derivative as pH adjustable enriching reagent and matrix for MALDI analysis of trace peptides

Journal Article Ren, Shi-fang ; Guo, Yin-long - Journal of the American Society for Mass Spectrometry

A functionalized carbon nanotube (CNT), CNT 2,5-dihydroxybenzoyl hydrazine derivative, was synthesized and used as both pH adjustable enriching reagent and matrix in matrix assisted laser desorption/ionization mass spectrometry (MALDI-MS) analysis of trace peptides. The derivative reagent, 2,5-dihydroxybenzoyl hydrazine, introduced phenolic hydroxyl and phenyl groups to the surface of the CNT. The former group can provide adjustable surface charge and a source of protons for chemical ionization, and the latter helps to keep strong ultraviolet absorption for enhancing pulsed laser desorption and ionization. It was found that the functionalized CNT was less twisted in a basic condition (pH 10.5), which affordedmore »« less

The Integration of a Structural Water Gas Shift Catalyst with a Vanadium Alloy Hydrogen Transport Device

Technical Report Barton, Thomas ; Argyle, Morris ; Popa, Tiberiu

This project is in response to a requirement for a system that combines water gas shift technology with separation technology for coal derived synthesis gas. The justification of such a system would be improved efficiency for the overall hydrogen production. By removing hydrogen from the synthesis gas stream, the water gas shift equilibrium would force more carbon monoxide to carbon dioxide and maximize the total hydrogen produced. Additional benefit would derive from the reduction in capital cost of plant by the removal of one step in the process by integrating water gas shift with the membrane separation device. The answermore »« less

A plankton-residue model to explain trace-element enrichments in oil-source rocks

Conference Piper, D Z ; Isaacs, C M - AAPG Bulletin

Sedimentary deposits enriched in organic matter commonly have high concentrations of many trace elements. In the past, trace-element enrichment was attributed to accumulation by precipitation/adsorption reactions under conditions of bottom-water sulfate reduction, or from a seawater that itself had an unusually high concentration of trace elements. Examination of the ancient and modern sediment record shows, however, that many trace elements in these deposits accumulated within an organic fraction whose composition closely approached that of modem plankton; their accumulation further required only a moderate rate of primary productivity. Specific examples are represented by the accumulation of Cu, Cd, Mo, Ni, andmore »« less
