    Residue analysis by multicolumn liquid chromatography — Herbicides in cereals (1980)
    Springer
    Chromatographia 13 (1980), S. 408-412 
    Details
    ISSN: 1612-1112
    Schlagwort(e): Multicolumn liquid chromatography ; Multidimensional chromatography ; Column switching ; Residue analysis ; Herbicides ; Cereals
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie
    Notizen: Summary The application of multicolumn HPLC in the determination of residues of a new herbicide and its main metabolite in green plants, grains and straw of different cereals is demonstrated. The columns are combined on-line by column switching and UV-detection is used. Due to the high separation power of multidimensional liquid chromatography only a simple and fast sample pretreatment is required resulting in a detection limit of 10−8 g/g.

    Optimization of throughput in preparative column luquid chromatography by column overloading and partial fractionation of the effluent (1985)
    Springer
    Chromatographia 20 (1985), S. 657-663 
    Details
    ISSN: 1612-1112
    Schlagwort(e): Preparative column liquid chromatography ; Optimization of throughput ; Column overloading ; Adjustment of fraction collection

    Thema: Chemie und Pharmazie
    Notizen: Summary The criteria for the optimization of preparative chromatography are sample throughput and product purity. It is shown for column liquid chromatography that the throughput has been maximized for a given purity by column overloading and appropriate fractionation. The size and position of the fraction must be determined by chemical analysis, since overlapping peaks under overloading conditions are usually distorted compared to the peaks of the same amounts of pure compounds. With overloading of the column larger particles can be used as column packings without reduction of the separation effect.
