Paper Abstract

In analytical chemistry so-called 'capillary waveguide cells' are used as effective optical cells with a low sample volume and a high optical pathlength. In this paper we will demonstrate that the concept of liquid core guiding, when the test liquid is really used as the optical core, is the most effective one. Guiding and coupling properties of different capillaries are investigated for different diameters of fibers and capillaries. Examples for using a liquid core guide cell as a biosensor is discussed as well as an example for 'fill once' (mu) l capillary cell.
