  • Aqueous and organic GPC of food
    determine many of its final properties and therefore its end-use suitability for different applications. GPC with Universal Calibration, employing a viscometer in combination with a differential refractive index detector, is used to determine accurate molecular weights for biopolymers
  • Detection of Chiral Compounds Using HPLC with CD Detection
    is toxic or mutagenic. Chiral detection has previously been limited to optical rotary dispersion (ORD) or polarimetry. Optical rotation-based detectors are based on differences in refractive index. Circular dichroism-based detectors differentiate enantiomers by measuring differences between
  • Living anionic polymerization of methyl methacrylate
    . GPC-8020 equipped with a refractive index detector. We used the. following scattering length densities  for the analyses of the SANS. data: thf-d = 6.4 Â 1010 cmÀ2, benzene-d = 5.4 Â 1010 cmÀ2 and PZN =. 5.7 Â 109 cmÀ2. Figure 2. Reaction scheme for catalytic living anionic polymerization

  • Medical Device Link .
    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
  • Molecular Weight Determination of Carbonic Anhydrase with the BI-MwA (.pdf)

  • Fiber Optic Technology (.pdf)
    from one transparent medium to another, the light is affected by the interface. between the two materials. This occurs because of the difference in speeds that the light can travel through different materials. Each material can be described in terms of its refractive index, which is the ratio
