This extensive Web site is the home page of the Chemical Sensors Research Group at the Warsaw University of Technology, headed by Professor Zbigniew Brzozka. Chemistry students can find tutorials in such subjects as Ion-selective Electrodes and Micro Total Analysis Systems. Users can view many papers in topics that include Microflow-cell Potentiometric Transducers and anion buffering. The site also provides a preview of the software the group has developed for data acquisition, pH meters, and spectrometers. Scientists can also learn about upcoming analytical chemistry and optical sensors conferences.
