The effect of electrophoretic migration on the concentration distributions in free zone electrophoresis is evaluated using a non-diffusional model. It is shown that sample constituents that have a mobility higher than that of the carrier constituent

Uremic blood samples were analyzed for ionogenic substances using analytical isotachophoresis. Multicomponent separations proved that the uremic state shows significant differences from the normal state, especially with regard to anionic low-molecula

The fundamental definitions of resolution and separability in isotachophoresis are given and extensively discussed. The resolution of a constituent is given as its fractional separated amount and can vary between zero and unity. The steady-state conf

Free theophylline was isolated from human serum by ultrafiltration and analysed in a leading electrolyte of 7.5 mM morpholinoethanesulphonic acid with ammediol as a counter ion at pH 8.90 and alpha-alanine as a terminator. The UV (280 nm) absorbance

The importance of the inside diameter of the separation compartment of electrophoretic equipment in which tubes are used in achieving optimal stabilization against conventive disturbances and for limiting the temperature increase is demonstrated. Bot

Resolution, load capacity and separation efficiency in isotachaphoresis are experimentally evaluated and the results are compared with the theoretically expected values. The theoretical and experimental results show good agreement and confirm the rel

An isotachophoretic system is described for the separation and identification of urinary purine and pyrimidine bases and nucleosides. For a better discrimination and interpretation of the UV profiles, well-defined non-UV-absorbing substances were int

Uremic ultrafiltrates (and normal serum, for comparison) were fractionated by means of gel filtration. The collected fractions were further investigated by combined analytical techniques: "high-performance" liquid chromatography, gas chromatography,

A system is discussed that makes use of two PTFE narrow-bore tubes with different internal diameters. In the pre-separation narrow-bore tube, which has the larger internal diameter, a high preparation current is permitted. At a well defined distance

Purine and pyrimidine metabolism receive attention from a rapidly growing number of workers in the field of inborn errors (1), hematology (2), immunology (3) and oncology (4,5). The availability of metabolite profiles of body fluids and cell contents
