摘要:
The main limitation of multi-detector GPC arises from the nature of detector sensitivities in the tails of a polymer distribution. In the low molecular weight tail of this distribution, molecular weight-sensitive detectors (such as a capillary viscometer or a static laser light-scattering photometer) have low sensitivity while concentration detectors (e.g., differential refractometer) have high sensitivity. This situation is reversed in the high molecular weight tail.
