Abstract:: A high-spectral resolution laser-excited molecular fluorescence system was developed that utilizes a pulsed supersonic expansion to simplify the fluorescence excitation spectra of large, gas-phase aromatic molecules diluted in an excess of a monatomic gas. A microcomputer was used to control and synchronize the instrumental components, which included a Chromatix CMX-4...

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...

Abstract:: A specially designed gas chromatograph with both TCD and FID has been tested for the measurement of the diffusion coefficients of methane and propane in helium. Knox's arrested elution technique(⁴) was used and yielded a value of 0.6431 cm²/sec averaged with the value obtained by Yang and Hawkes(⁷). Values of...

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...

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...
