Microdialysis sampling in conjuction with other analytical techiques is presented for the monitoring of wastewater from a beverage plant. Microdialysis sampling achieved in situ sampling and sample clean-up for glucose, fructose, sucrose, F-, Cl-, NO3 2-, PO4 2-, SO4 2-, Mg+2, K+, Ca+2, Na+, Zn+2 and Ni+2. High extraction fractions achieved for these analytes demonstrated the potential to apply microdialysis to sample from a complex environmental matrix. Enzymatic assay was employed as a complimentary technique for determining concentration of the saccharides. These results show that profiling of analytes with a combination of analytical techniques is an essential first step to developing a methodology for environmental monitoring. Combining the versatility of microdialysis sampling with chromatography and sensitive electrochemical detection presents a generic approach to achieving real-time monitoring of analytes that are associated with environmental pollution, especially in a wastewater matrix.
