    Notes: Summary The use of non-segmented flow, post-column reaction detection is evaluated for use with miniaturized HPLC. Non-segmented open-tubular reactors with internal diameters 0.1 mm to 0.25 mm and packed-bed reactors with internal diameters of 1 mm, filled with 5 and 10 μm particles are evaluated theoretically and experimentally with respect to band broadening and pressure drop characteristics. An integrated system consisting of miniaturized HPLC (1 mm i. d.) columns and compatible hardware is described. An example of the separation of catecholamines is given.

    Design and application of a post-column extraction system compatible with miniaturized liquid chromatography (1984)
    Springer
    Chromatographia 18 (1984), S. 5-10 
    Details
    ISSN: 1612-1112
    Keywords: Miniaturized HPLC ; Post-Column Extraction Detection ; Segmented-Flow Open-Tubular Reactors ; Membrane Phase Separator ; Anti-Cancer Drugs

    Topics: Chemistry and Pharmacology
    Notes: Abstract An on-line, post-column, extraction system suitable for use with miniaturized HPLC (0.7–1 mm i.d. columns) is described. The system consists of a 30° angle segmenting tee, a PTFE extraction coil of variable length and a membrane phase separator. The internal volume of the phase separator is less than 1 μl. The total variance contribution of the system is between 1 and 6 sec2. The determination of the anti-cancer drugs VP 16 and VM 26 in urine by means of reversed-phase HPLC and fluorescence detection, using both on-column preconcentration and the present miniaturized post-column extraction system is presented as an application.
