Paper Abstract

A portable analytical system for the characterization of liquid environmental samples and beverages in food control was realized. The key element is the implementation of contactless conductivity detection on lab-on-a-chip basis ensuring the system to be operated in a label free mode. Typical target molecules such as small ionic species like Li+, Na+, K+, SO4 2- or NO3-, organic acids in wine whose concentration and ratio to each other documents the wine quality, or caffeine or phosphate in coke were detected. Results from sample matrices like various beverages as water, cola, tea, wine and milk, water from heaters, environmental samples and blood will be presented.
