    5.2.5 Detectors Of UPLC

    • 983 Words
    • 4 Pages

    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

    this experiment is to extract and find quantitative amount of Beta-carotene from a carrot sample. The raw product(carrots) was extracted using simple distillation. The purity of the product will be characterized using percent yield‚ thin layer chromatography‚ Beer’s Law‚ and UV-vis. Beer’s law is used because in this experiment we are comparing our extraction of B-Carotene to the Stock B-Carotene. Beer’s law shows that absorbence of light at a specific wavelength is proportional to the concentration

    specific and accurate reverse phase high performance liquid chromatographic method was developed for the simultaneous determination of chlorpheniramine maleate and phenylephrine in tablet dosage forms. A reversed-phase C-18 column (250 mm × 8 mm i.d.‚ particle size 10 µm) column with mobile phase consisting of acetonitrile and phosphate buffer 55:45 (v/v) (pH 5.6 ± 0.02‚ adjusted with triethylamine) was used. The flow rate was 1.0 ml/ min and effluents were monitored at 255 nm. The retention times
