Long term-functional tests of previously developed fluidic connections to a continuous flow micro-cell revealed troubles such as bubble formation and analyte loss. In order to overcome these drawbacks alternative technical solutions are investigated concerning both the materials and the flow-pattern transferring as well as the assembly technique. Thus, the sand blasting of borofloat glass -as well as the lithography of photosensitive glass (FOTURAN)- are used for generating the openings, araldite is used as a glue and a sandwich technique is approached in order to obtain the reservoir with openings for the capillaries. Functional tests are in progress with in–house built borosilicate glass adaptors.
