“…Us-(UL-+ Uc+) Cs-= Q-" UL-(Us-+ Uc+) (4) where Uc+ is the effective mobility of the common counter-ion, while CL-and Cs-are the concentrations in their respective zones. When the concentration of hydrochloric acid of the leading electrolyte is lower than that of SDS, the concentration of SDS in capillary tube should reproduced below the CMC without any interaction between them, or vice versa.…”

“…Isotachophoresis measurement has proved to be a powerful tool for the separation and quantification of ionic species, and has been applied in various fields; for example, biochemistry [1][2][3][4], medicinal chemistry [5][6][7][8], industrial chemistry [9][10][11][12], environmental chemistry [13][14][15][16], and elslewhere [17][18][19][20]. These studies have been carried out for analyses of organic acids, polymers, and metals.…”

Abstract:The analytical procedure for the separation and quantification of bulk and micellar phases for sodium alkyl sulfates has been investigated by a capillary-type isotachophoresis using a potential gradient detector. Monomer solutions were distinguished from micellar solutions at pH 5.5-6.0; hydrochloric acid-L-Histidine mixture was used as the leading electrolyte and 2-(N-Morpholino) ethanesulfonic acid as the terminating electrolyte.The potential unit value (PU value) due to the monomer solutions was larger than that due to the micellar solutions. The zone length due to monomer solutions increased with increasing concentration of surfactant until a given concentration (CMC); beyond this point the values became constant. On the other hand, the zone length due to micellar solutions increased from this point. We report an applicability of capillary-type isotachophoresis to determination of the CMC's and aggregation number for various sodium alkyl sulfates.

Plant Cell Wall, a Challenge for Its Characterisation

The plant cell wall is a complex 3D network composed of polysaccharides, lignin and proteins. The knowledge of the structure and content of each cell wall polymer is a prerequisite to understand their functions during plant development and adaptation but also to optimise their industrial applications. The analysis of cell wall compounds is complicated by their multiple molecular interactions. In this review, we present numerous methods to purify, characterise and quantify proteins, polysaccharides and lignin from the wall. Two kinds of approaches are detailed: the first presents in vitro methods which involve the breakdown of the molecular linkages between polymers thanking to chemical, physical and/or enzymatic treatments. The second approach describes in situ methods that allow the cell wall polymer characterisation thanking to many analytical techniques coupled with microscopy. If microscopy is the common point of all of them, their development is associated with improvement of analytical techniques, increasing their power of resolution.
