A gas chromatographic procedure was developed for the determination
of nanogram quantities of hydrocyanic acid using a
flame ionization detector. Excellent chromatograms were obtained
on a porous polyaromatic polymer column (Porapak Q) at 60°C. The
procedure was employed for the analysis of HCN in aqueous cyanide
solutions. Solutions as low...
The lack of availability of a single, complete paper on the
analysis of a digital data acquisition system for in situ oceanographic
measurements brought about the present work. In order to compile
an accurate technical paper on such a complex system, it was necessary
to design, construct, and calibrate a...
An instrument was developed which performs analysis of the
oxygen content of air by means of a commercial polarographic oxygen
electrode. The oxygen analyzer is part of a portable instrument
which converts the current from the oxygen electrode into a pulse
whose width is proportional to the oxygen concentration. This...
The Kroll Process for the production of zirconium utilizes
the reduction of zirconium tetrachloride with metallic magnesium.
Control of the magnesium content of the final zirconium metal is
essential, as residual magnesium adversely influences the properties
of zirconium.
In this thesis a volumetric method has been presented for the
determination...
An all-glass gas chromatograph was developed for the analysis
of corrosive metal halides. Included in the apparatus is a new liquid
sampling system designed for fast repetitive sampling of corrosive
liquids in an inert atmosphere. A flame photometer detector was developed
to permit the detection of corrosive solutes in the...
Many different aspects of the determination of dissolved oxygen
by controlled potential coulometry were investigated to find a means
of measuring the oxygen content of natural waters. Rapid
sampling techniques, simplicity of operation, and rugged structural
features were stressed. Cells were designed to operate by either
internal electrolysis or external...
