    Microcolumn liquid chromatography/Fourier transform infrared spectrometry interface using a potassium bromide disk (1987)
    Springer
    Chromatographia 23 (1987), S. 512-516 
    Details
    ISSN: 1612-1112
    Keywords: Liquid chromatography ; Fourier transform infrared spectrometry ; Microcolumns ; Buffer memory technique
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary A redesigned interface is reported for use in the detection of microcolumn liquid chromatographic effluents with a Fourier transform infrared spectrometer. The solutes eluting from the column are continuously deposited onto a 50mm diameter KBr disk as a “buffer-memory”. The disk is rotated by a stepper motor with a controlling electronics. After the chromatographic run, the disk is simply transferred to the spectrometer and the transmission spectra are measured as the disk rotates. The use of such a large KBr disk as a substrate permits to obtain spectra of the components having a large capacity factor.

    Hydrocarbon group-type analysis with microcapillary-column liquid chromatography/conventional infrared spectrometry (1985)
    Springer
    Chromatographia 20 (1985), S. 279-282 
    Details
    ISSN: 1612-1112
    Keywords: Column liquid chromatography ; Microcapillary column ; Gasoline group analysis ; Conventional IR detection
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary Slurry-packed microcapillary column liquid chromatography with conventional infrared detection is described for the group-type analysis of gasolines. The results indicate that the three eluted groups, saturates, olefins and aromatics, from the microcapillary column are easily detected by conventional microcomputerized infrared spectrometer coupled with a Teflon flow-cell with a good signal-to-noise ratio. This study shows the feasibility of microcapillary column liquid chromatography combined with a low-cost, conventional infrared spectrometer as a routine tool which allows the analyst to use an LC-IR system effectively and economically.
