Apparatus for analysing a measuring substance which is dissolved in a solvent, comprises a conduit 4 for transporting the dissolved measuring substance from a feed means 3 to a measuring location 12, wherein the feed means 3 is designed to optionally feed a solvent or dissolved measuring substance into the conduit 4, characterised in that the conduit 4 comprises more than two separate capillaries connected in parallel over at least part of its length. Each separate capillary is arranged to have identical flow times from the feed means to the measuring location. Preferably the conduit is arranged as a polycapillary area 9 which has N parallel connected capillaries (21a, 21b, 21c; 62a, 62b, Fig 2). The conduit may contain a chromatography column 11 and the capillaries may have a hydrophobic inner coating. Advantageously the apparatus improves the signal-to-noise ratio of the analysis. |
