Tiivistelmä
Complex or unknown liquid analysis requires extensive instrumentation and laboratory work; simple field devices usually have serious limitations in functionality, sensitivity, and applicability. This communication presents a novel, effective, and simple approach to fingerprinting liquids. The method is based on nonspecific interactions of the sample liquid, a long lifetime luminescent europium label, and various surface modulators in an array form that is readily converted to a field analysis μTAS system. As compared to existing e-nose or e-tongue techniques, the method is unique both in terms of sensitivity and usability, mainly due to the well-known unique properties of the europium label. This communication demonstrates the use of this new method in distinguishing different wines, waters, alcohols, and artificially modified berry juices.
