Nitrogen Isotope Separation by Ion Exchange Chromatography

Enriched stable isotopes of many elements have been widely used in many aspects and such isotopes have been primarily used as the tracer for agricultural and biochemical studies and the availability of the isotopically labeled compounds have been now extensively increasing. Chemical exchange separation of isotopes is based on the equilibrium fractionation of isotopes between two phases, ion exc...

Development of Palladium-Alloy Membranes for Hydrogen Separation and Purification

This paper summarizes R&D activities and progress at NORAM Engineering and the University of British Columbia (UBC) on preparation and testing of thin palladium-based membranes and their applications. Most of these activities were carried out internally at NORAM, some jointly with UBC and their spin-off company, Membrane Reactor Technology (MRT) through a wide range of projects. Key results out...

Microfabricated Palladium-based Membranes for Hydrogen Separation

An innovative process for the microfabrication of Pd-based membranes (Pd and Pd-Ag) on a <110> silicon wafer is presented. Pd-Ag alloy films containing 23wt% Ag are prepared by a dual-sputtering from pure Pd and Ag targets. In the first step, deep grooves are KOH etched in one side of a <110> oriented silicon wafer, leaving membranes with a thickness of ca. 50 μm. After Pd alloy deposition on t...

Ampholyte-displacement chromatography for the separation of serum proteins.

The antibody fraction (less than 6ml) was added to immobilized enzyme (2ml of packed gel). The antibodies were recycled for 2h and the unattached antibodies washed from the gel for 1 h. Specific antibodies were eluted by washing with citric acid (0.1 M, pH2.2). Experiments marked with an asterisk were performed simultaneously. The molecular weights of immunoglobulin G and creatine kinase were t...

Micromachined Palladium - Silver Alloy Membranes for Hydrogen Separation

This paper presents wafer-scale palladium silver alloy membranes, fabricated with a sequence of wellknown thin film and silicon micromachining techniques. The membranes have been tested in a gas permeation system to determine the hydrogen permeability and hydrogen selectivity. Typical flow rates of 1 mol H2 /m.s have been measured with a minimal selectivity of 1500 for H2/He. The membranes have...
