Flame ionization detection of hydrocyanic acid ; Analysis of trace aqueous solutions

Creator:: Claeys, Robert Raymond
Abstract:: 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 design and evaluation of a recording conductometric titrator

Creator:: Knarr, Richard Dennis
Abstract:: A Heath EUW-20A Servo-Recorder was converted to a self-balancing, recording Wheatstone bridge. The EUW-20A 10000Ω slide-wire was used as the variable resistance arm of the bridge, the servo-amplifier was used as the bridge unbalance signal detector, and the servo-motor was used to balance the bridge automatically. The bridge was arranged...

Full Text:: capacitance causes a phase difference between the a -c potentials of two of the bridge arms. This phase

Gas chromatography of metal halides

Creator:: Dennison, James Eugene
Abstract:: 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...

Optimization by transfer function estimation of the galvanovoltammetric determination of dissolved chlorine in a flowing stream

Creator:: Miller, Clinton Earl
Abstract:: Optimization of the galvanovoltammetric determination of dissolved chlorine in a flowing stream was achieved through the use of an analog computational device and improvements in the design of the galvanovoltammetric cell and accompanying electronic circuitry. An analysis system, applicable to industrial use over a range of flow rates and dissolved...

Stationary electrode voltammetry and chronoamperometry in an alkali metal carbonate-borate melt

Creator:: Petcoff, Darrell George
Abstract:: The electrochemistry of the lithium-potassium-sodium carbonate-borate melt was explored by voltammetry and chrono-amperometry. In support of this, a controlled-potential polarograph and associated hardware was constructed. Several different types of reference electrodes were tried before choosing a porcelain membrane electrode containing a silver wire immersed in a silver sulfate melt. The...

Study of simultaneous codeposition of metals at solid electrodes

Creator:: Yindepit, Somrat
Abstract:: As with many pairs of metals, the electrodeposition of Pb-Tl, Cu-Cd, and Cu-Ni at solid electrodes yielded partial polarization curves shifted from the polarization curves of the single metals. The curves for the more noble metals (Pb, Cu) were shifted negatively while the less noble metals'(Tl, Cd, Ni) curves were...
