    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.
