    1.5.2.5 Detectors The detectors used in UPLC should be able to handle very fast scanning methods because half-height peak widths of less than one second are usually obtained with columns packed with 1.7 µm particles. The detector must be able to give high sampling rate adequate to capture enough data points across the peak for an accurate and reproducible integration of analyte peak. The dispersion (volume) of the detector flow cell must be minimal to maintain separation efficiency. Conceptually

    Experiment # 4 Paper Chromatography 1. Why is the chromatogram developed in an essentially closed system? - The chromatogram is developed in a closed system in order to prevent the solvent to evaporate. Most solvents used in the chromatograph are toxic and flammable. It is also put in a close system to reduce the chance of outside factors affect the chromatograph. 2. What is the main advantage of 2-dimensional paper chromatography over a 1-dimensional one? - The
