method for diagnosing corrosion of an underground storage tank system is provided. The method includes the following steps. A sample from the underground storage tank system is collected, wherein the sample comprises at lease one metal ion. The species and the concentration of the metal ion in the sample are detected by an analysis instrument. A concentration threshold value is determined from a database according to the species of the metal ion. A mapping step is performed, wherein the concentration of the metal ion and the concentration threshold value are compared to diagnose if the underground storage tank system is corroded.

Disclosed herein is a methodology for analyzing isoenzymes using capillary zone electrophoresis ('CZE') techniques. Briefly, an isoenzyme-containing sample and a substrate capable of being catalyzed by said isoenzyme into a reaction product are introduced into a capillary column comprising a buffer. Most preferably, the buffer contains the substrate prior to introduction of the sample into such substrate-buffer. CZE separation techniques are applied to the column such that the isoenzymes are separated from each other into discrete zones. The separation techniques are terminated such that product is rapidly generated by the catalytic conversion of substrate by the isoenzymes, and accumulated, within each discrete zone, followed by detection of product. Information regarding the relative distribution of the isoenzymes can be derived from the relative distribution of the product.
