Paper Abstract

Interest in chemical sensor and analyzer technology has sky rocketed in recent years due to a growing desire to increase our understanding and control of processes. Through advances in instrumentation, analytical chemists can provide analyses for smaller samples and more dilute solutions. Implementation of computer programs based on multivariate statistical algorithms makes possible obtaining reliable information from long data vectors that contain large amounts of extraneous information, for example, noise and/or analytes that we do not wish to control. Three examples are described. Each of these applications requires the use of techniques characteristic of modern analytical chemistry. The first example, using a quantitative or analytical model, describes the determination of the acid dissociation constant for 2,2'-pyridyl thiophene using archived data. The second example describes an investigation to determine the active biocidal species of iodine in aqueous solutions. The third example is taken from a research program directed toward advanced fiber optic chemical sensors. The second and third examples require heuristic or empirical models.
