Currently the separation of gallium from weapons plutonium is achieved using complex aqueous processing involving solvent extraction and ion exchange; this process generates large quantities of wastewater containing radioactive materials. At Los Alam

The feasibility of using centrifugal, multicolumn elution chromatography in conjuction with eluate monitoring is being studied. A preliminary prototype system has as many as four columns mounted in a spinning rotor that passes through a stationary ph

High-resolution liquid chromatography is being applied to the characterization of refractory organic compounds present in coal conversion streams at concentrations as low as a few micrograms per liter. The chromatographic system, which was previously

A high-resolution anion exchange analyzer was adapted for determination of u.v.-absorbing compounds in water at μg 1 −1 levels. The samples were concentrated prior to analysis by vacuum distillation and freeze-drying. Seventy-seven peaks were obta

A simple routine for distinguishing and measuring the positions and areas of overlapping peaks comprising a complex chromatographic "envelope" has been developed for a small on-line computer. The degree of peak overlap is such that no minima and only

At the current state of development, high-resolution liquid chromatographs for analyses of complex physiologic fluids require relatively long analysis times and consequently the rate at which analyses can be done is limited. This rate can be increase

A series of miniature photometers has been developed for use as on-stream detectors in systems for liquid chromatography. All of the detectors feature dual-beam, dual-wavelength operation without mechanical or electrical switching of either wavelengt

An improved automated, high-resolution anion-exchange analyzer has been developed for detecting and quantifying carbohydrates in body fluids. This new analyzer is more sensitive than the earlier model and much simpler to construct, operate, and maint
