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 from a conductivity detector (mounted in this pre-separation narrow-bore tube) the final separation narrow-bore tube, which has the smaller internal diameter, is coupled to the pre-separation narrow-bore tube via a T-piece. The smaller internal diameter of the final narrow-bore tube permits work at a higher current density during final separation and detection by means of conductivity and UV absorption detectors. The zones of interest can easily be separated from the sample zones, migrating isotachophoretically in the pre-separation narrow-bore tube via the detector. |
