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...

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...

Application of piezoelectric quartz crystal as partition detector : development of a digital transducer

Creator:: Janghorbani, Morteza
Abstract:: AT-cut piezoelectric quartz crystals coated with low vapor pressure materials are evaluated as digital transducers in completely digital detection systems for monitoring gas streams. Mathematical relations describing the detectors are developed and tested. Specific application is made to monitoring gaseous sulfur compounds commonly found in stack effluents of pulp mills....

Optimization of the continuous analysis Pearl-Benson method for lignosulfonates

Creator:: Blaine, Roger Lee
Abstract:: A procedure is described for the optimization of a previously described continuous analysis adaptation of the Pearl-Benson or nitroso method for estimation of spent sulfite liquor (SSL) or ligno-sulfonates. The optimized procedure has a response time of 6.5 minutes. In order to monitor samples whose SSL concentration is between 0...

Coulometric determination of dissolved oxygen

Creator:: Healy, Michael Lyon
Abstract:: 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...
