    The use of deuterated solvents in high-performance liquid chromatography-Fourier transform infrared spectrometry (1985)
    Springer
    Chromatographia 20 (1985), S. 112-116 
    Details
    ISSN: 1612-1112
    Keywords: Column liquid chromatography ; FTIR detection ; Aqueous eluents ; Deuterated compounds
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary Deuterated compounds have been used as mobile phases for microcolumn high-performance liquid chromatography (HPLC) employing flow-cell Fourier transform infrared spectroscopy for detection. Separations were carried out on adsorption, reversed-phase, non-aqueous size-exclusion and aqueous size-exclusion chromatographic columns. Due to the IR transparency of deuterated compounds in a C−H stretching region they represent nearly ideal eluents in terms of universal detection. In addition, due to the shift in the absorption wavenumber following deuteration, deuterated solvents allow FTIR detection of solutes in other regions, where otherwise it would be prohibited, or sensitivity sacrified by interfering solvent absorption.

    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.
