Electrolyzers tubular

The need to measure concentrations in very small volumes is not restricted to biological systems. For example, open tubular columns for liquid chromatographic separations offer the advantage of increased resolution, but because their internal diameters may be as small as 15 pm, the amount of material in the eluted peaks is very small. Thus, the use of these columns requires detectors that can be used with low concentrations in small volumes. Jorgenson and co-workers showed that this could be accomplished by the insertion of a 10-pm-diameter, cylindrical electrode made from a carbon fiber into the end of the column [4]. The close fit between the column wall and the fiber ensured that a large fraction of the eluting molecules were electrolyzed. When the electrochemical data were collected in a voltammetric mode, the resolved compounds could be classi-... 

Hydrogen freed in the electrolyzer is sucked off by a liquid-piston type rotary blower and led under slight overpressure of 10 to 15 mm water column through an iron manifold to tubular water coolers, in which the temperature will drop from some 70—75 °C to 25 °0. From the cooler, the gas passes either directly...
