Several affinity screening methodologies that include MS-based readout and work under protein-excess conditions have been developed in the past decade [1]. Some examples include affinity selection/mass spectrometry (ASMS Abbott Labs [10]), size exclusion chromatography with LC-ESI-MS (see Chapter 2 and 3 [11-19]), the use of coupled or non-coupled pulsed ultra-filtration/mass spectrometry (summarized in this chapter [11, 20-23]), restricted access phase chromatography (see Chapter 5 [24, 25]), capillary electrophoresis [26, 27], target shift mass spectrometry [28], and multitarget affinity/specificity screening (MASS, see Chapter 10 [29, 30]). 

The observations and questions raised by these workers helped stimulate the experiments which are presented here. In this work, size exclusion chromatography with low angle laser light scattering detection (SEC/LALLS) was used to probe the distribution of branching functionality in multiarm macromolecules of styrene/isoprene and styrene/buta-... 

Size-exclusion chromatography with Sephadex gel was used to study changes in the organic matrix as it passed through the treatment process at Vigneux. The results obtained are presented in Figures 3-7. Points where significant differences were observed are indicated by arrows. 

Miller and Ishida [11] combined size-exclusion chromatography with diffuse reflectance FUR -spectroscopy to identify the hydrolysis and condensation products of phenyltriethoxysilane in mixed organic-aqueous media. Pohl and Osterholtz [8, 12] followed the condensation of alkylsilanols using 3C- and 29Si-NMR spectroscopy and found condensation to be catalyzed by both deuteroxide anion and deuterium ion. Savard etaL [13] used H-NMR spectroscopy to follow the rate of hydrolysis and condensation of 3-methacryloxypropyltrimethoxy-silane as a function of the pH. These authors used the Lentz technique of derivatization to determine the structures of some of the condensation products.

Gardner et al. [9] recognised that because component separations on size exclusion columns with distilled water are affected by chemical physical interactions as well as component molecular size, distilled water size exclusion chromatography will also fractionate dissolved metal forms. These workers interfaced distilled water size exclusion chromatography with inductively coupled argon plasma detection to fractionate and detect dissolved forms of calcium and magnesium in lake and river waters. 

Leung et al. [4] determined polyacrylamides in coal washery effluents by ultrafiltration size exclusion chromatography with ultraviolet detection. A column of TSK 500 PW hydrophilic and semi-rigid porous polymer gel was used with 0.05m sodium sulphate as mobile phase. 

Adamic and Bartak [6] used high pressure aqueous size exclusion chromatography with reverse pulse amperometric detection to separate copper(II) complexes of poly(amino carboxylic acids), catechol and fulvic acids. The commercially available size exclusion chromatography columns were tested. Columns were eluted with copper(II) complexes of poly(aminocarboxylic acids), citric acids, catechol and water derived fulvic acid. The eluent contained copper(II) to prevent dissociation of the labile metal complexes. Reverse pulse electrochemical measurements were made to minimise oxygen interferences at the detector. Resolution of a mixture of DTP A, EDTA and NTA copper complexes was approximately the same on one size exclusion chromatography column as on Sephadex...
