    Chinese hamster ovary (CHO) cell line. The first set of data is from the flow-mode detector in conjunction with an SEC separation. The supernatant is characterized by using a refractive index (RI) detector and simultaneous static and DLS detectors coupled to an HPLC running in the SEC mode. The SEC

  • Medical Device Link .
    /visible light detectors have been the universal type for liquid chromatography, but light detectors based upon refractive index, infrared absorbance, evaporative light scattering, and fluorescence, as well as on mass spectrometry, have also been widely used. HPLC using mass spectrometer detectors has
