Gradient high-performance liquid chromatography (HPLC) has been useful for the characterization of copolymers (14-19). In such experiments, careful choice of separation conditions is a conditio sine qua non. Otherwise, low resolution for the polymeric sample will obstruct the separation. However, the separation in HPLC, dominated by enthalpic interactions, perfectly complements the entropic nature of the SEC retention mechanism in the characterization of complex polymer formulations.

Quantitative analysis of radioactivity remaining uuexlracled from soil was carried out by oxidation of the residue (combustion) and recovery of the evolved uCO . The majority of analyses of aqueous samples and solvent extracts were carried out by gradient high-performance liquid chromatography (HPLC). Co-ehronialography of radio peaks with authentic reference standards was used for initial characterization and quantification. [Pg.106]

Details of the techniques that have been applied here are beyond the scope of this chapter. Suffice it to say that the most promising current method to measure chemical and molecular weight distributions of copolymers is SEC followed by gradient high-performance liquid chromatography (44,45).

A combination of liquid chromatography under critical conditions using coupled density and RI detection in one dimension, and gradient high performance liquid chromatography in the second dimension, was used in the two-dimensional chromatographic analysis of the oligomers present in fatty alcohol ethoxylates. Full resolution was achieved. 6 refs. [Pg.100]
