Multiangle laser light-scattering detector

At the moment, one recommends to determine the molecular characteristics of pectins using SEC chromatography equipped with a differential refractometer, a multiangle laser light scattering detector and a viscometer as previously described [25]. This technique needs no calibration with the usual molecular weight standards such dextrans and pullulans... [Pg.23]

In recent years, multiangle laser light scattering (MALLS) detectors have become highly popular in SEC and also in FFF (see,e.g. [135-140]), since they also determine molar masses and molecular dimensions on an absolute basis. Here, the scattered light is simultaneously detected at various angles so that an extrapolation to zero angle is possible. Such instruments are commercially available from several companies. As an important development, the FFF-MALLS combination is discussed in a separate chapter (see Sect. 4.1.2). [Pg.96]

The star polymers obtained with the bromoester-type calixarene-based initiators were analyzed by SEC equipped with a multiangle laser light scattering (MALLS) detector. The arm numbers were well controlled (close to the initiator s functionality), although the octafunctional initiator MI-51 induced star—star coupling in the styrene-polymerization at conversions higher than 20%.421 A similar series of tetra-, hexa-, and octafunctionalized initiators with calixarene cores were synthesized for sulfonyl chloride versions (MI-41, MI-48, and MI-52) and employed for copper-catalyzed MMA polymerizations.343... [Pg.500]

PHEMA, the theoretical value iWntheo calculated with the monomer-to-initiator molar ratio and the conversion was used (for selected samples, the validity of this assumption was confirmed by GPC with a multiangle laser light-scattering (MALLS) detector). The following discussion will be based on M theo for absolute M and /Ww,PEG/Afn,PEG fot absolute polydispersity index. [Pg.203]
