    Details
    ISSN: 0935-6304
    Keywords: Gas chromatography ; Capillary, glass ; Comparison of FID, ECD, FPD for detection limit. linearity, peak shape etc. ; Practical results for pesticide residue and coal hydrogenation products given ; Concentration dependent detectors in capillary GC interesting, when optimized ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: A comparison of the characteristics and Performance of the flame ionization, electron capture, and flame photometric detectors with capillary columns is described. Factors which may affect the limits of detection, linearity, chromatographic peak shape, and other detector performance characteristics are discussed and compared with the results of a model derived for the behavior of concentration and mass flow-rate dependent chromatographic detectors used with capillary GC systems. Examples are given of highly complex and labile mixtures such as pesticide residues and products from coal hydrogenation.

    Fused-silica microparticulate packed column HPLC-split flow gradient elution (1986)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 9 (1986), S. 84-88 
    Details
    ISSN: 0935-6304
    Keywords: Liquid chromatography ; Fused silica capillaries ; Micro-HPLC ; Gradient elution ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Fused-silica microparticulate packed columns are demonstrated to have equal or better separation efficiency and resolving power than conventional 4.6 mm i.d. packed columns. While neither separation efficiency nor resolving power is an inherent consequence of capillary column use, there re potential advantages of using fused-silica capillary columns, particularly when microparticulate particles of 1 to 5 üm are used in the gradient elution mode. Gradient elution techniques compatible with flow rates below 30 μL/min are discussed. Spli-flow gradient elution of twenty PTH amino acids using 10 and 40 cm × 0.54 mm i.d. columns packed with 4 μm Micro-Pak PTH-AA particles is demonstrated. Detection limits of 0.1-0.3 picomoles are meaured for PTH amino acids and 0.01-0.02 picomoles for tricyclic antidepressant drugs.

    Solute focusing technique for on-column injection in capillary gas chromatography (1983)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 6 (1983), S. 554-559 
    Details
    ISSN: 0935-6304
    Keywords: Gas Chromatography ; On-column Injection ; Capillary Columns ; Solute Focusing ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: A novel solute focusing technique for on-column injection of liquid samples onto capillary GC columns is described. The focusing technique allows injection of 8.0 microliters or more of sample without producing the peak distortion or splitting observed under conventional on-column injection conditions. The experimentally determined performance of the technique is given for a wide volatility range sample. Solute focusing is useful in situations where on-column injection of 1.0 microliter or greater is required.

    Multi-element selective radio frequency plasma detector for capillary gas chromatography (1988)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 11 (1988), S. 75-81 
    Details
    ISSN: 0935-6304
    Keywords: Capillary gas chromatography ; Element selective detection ; Radio frequency plasma ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: A radio frequency plasma detector for element specific detection in gas chromatography is described. The detector is comprised of a radio frequency (300 kHz) discharge between electrodes in helium, and utilizes a low-resolution emission spectrometer to monitor selected spectral emission lines produced when the helium discharge decomposes and excites the atomic constituents in the chromatographic column effluent. The spectrometer is tuned to an atomic emission line in the near-infrared portion of the spectrum, and the emission intensity from the discharge region of a selected line is used to monitor the concentration of the element producing that line. Acceptable detector sensitivity was achieved by the use of a high-throughput optical system. Selectivity was achieved by a combination of correct line selection, plasma and carrier gas purification, and plasma gas doping.
