Benzo(a)pyrene (BaP) which presents native fluorescence in solution has been determined in waters by synchronous solid-phase spectrofluorimetry. The relative fluorescence intensity of BaP fixed in Sephadex G-25 gel is measured after being packed in a

The monomers of heterocyclic compounds and surfactants having a small head group and a long alkyl chain are adsorbed on the Sephadex gels G-10 and G-200. The adsorption of the former compounds is striking, whereas that of the latter compounds is weak

Elution volumes of NaI and Na 125 I appear to differ significantly when chromatographed on Sephadex G-15 or G-10. Using distilled water as the eluent, radioiodide was eluted in the void volume of the column while NaI was found eluted after NaCl. Howe

There is good evidence that, in Sephadex gels, oligosaccharide series how (positive) linear free energy relations with respect to the degree of polymerisation. The distribution coefficients of disaccharides are thus a measure of the differences betwe

Tea infusion liquor was separated into molecular weight fractions on various grades of Sephadex gels and the antithiamin activity of these fractions was determined. It was found that tea liquor contains three molecular weight fractions that affect th

IEF of humic and fulvic acids (HA and FA) from various sources were carried out on a flat-bed of Sephadex gels G-75 with Ampholine of appropriate pH-range. From the Sephadex gels, fractions of a FA sample were collected separately. It was found that

We have investigated the influence of the degree of cross-linking of Sephadex gels and the polarity of the eluent on the separation of cis- and trans-cinnamic acids and concluded that the physical basis for the separations is hydrophobic interactions

O- Phosphoserine phosphohydrolase (EC 3.1.3.3) from bovine brain and kidney was found to exist in several molecular forms, which can be separated by chromatography on Sephadex gels. This is the consequence of a self-association process, that appears

Using gel permeation with Sephadex gels it was found that in surface waters the bulk of the dissolved species of Cd, Zn and Pb has a molecular weight in the ranee of 1000–5000. No significant difference in speciation in surface waters could be esta
