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...

Classification of stationary liquids in gas chromatography by infrared spectrophotometry

Creator:: De Briceno, Maria Betania Orduz
Abstract:: A classification of stationary liquids by infrared spectroscopy to evaluate the polarity was made using the solvent effect technique. The infrared C-Cl absorption frequency shift was measured for solutions of 1-chlorohexane dissolved in each stationary phase. These frequency shifts were correlated to the relative retention times of 1-octene/n-octane, trans-2-octene/n-octane and...

The obstructive factor in gas chromatography

Creator:: Thumneum, Pornpan
Abstract:: The study of the obstructive factor by Hawkes (11) showed a relation between the obstructive factor and velocity using a continuous method. Later, Bowers and Hawkes (12) developed a similar method with some improvements in the apparatus and found out that the obstructive factor was not flow dependent. This study...

Classification of stationary phases in gas chromatography

Creator:: Chong, Elee Elizabeth
Abstract:: Ultraviolet spectroscopy and dispersive solubility parameters correlated to the ratios of retention times have proven valuable in classification of gas chromatography stationary phases by the donor-acceptor properties. Iodine was directly dissolved into stationary phases and the absorption frequency shift of complexes was correlated with the carbon tetrachloride/chloroform retention ratio on...

Slow processes in gas-solid chromatography

Creator:: Burns, Walter Frederick
Abstract:: Gas-solid chromatography often has asymmetrical elution peaks. This is attributed to nonlinear isotherms, multi-energy adsorption sites, and slow processes. This study utilized a stopflow gas chromatograph with various NaOH and NaCl modified aluminas as adsorbents and methane as adsorbate to determine the influence of surface area and pore volume distribution...

The identification and quantitation of complex polycyclic aromatic hydrocarbon mixtures in environmental samples using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry

Creator:: Manzano, Carlos A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants and are mostly products of the incomplete combustion of organic material. PAHs are often found in environmental samples as a complex mixture of isomers. In addition, the same sources that produce complex PAH mixtures also produce other poorly characterized mixtures of organic compounds,...

A multivariate statistical approach to identifying organic compounds using an oscillating plasma glow discharge detector for gas chromatography

Creator:: Smith, Diane Lynn
Abstract:: An oscillating plasma glow discharge detector for gas chromatography is used to obtain fingerprint information about an analyte by combining both the average cell current and oscillation frequency signals. Five homologs each of the n-alkanes, 1-alkenes, 1-alkynes, 2-ketones and aldehydes are studied. Although triplicate determinations had some scatter due to...
