Chem. Basic Statistics This section outlines the use of the statistics encountered in Analytical Chemistry, and goes through the basic tools that you will use to approach statistical analysis in chemical measurement. We have not given extended accounts of complex or more specialized analytical techniques, which might be studied beyond first- and second-year courses. 343 (1992):812-813 Qualitative analysis is what. chemistry in the Instant Notes series, and to offer to students in chemistry and other disciplines some guid-ance on the use of analytical techniques where they are relevant to their work. B.S 4- Class 1-Introduction to analytical chemistry 1. 2.1: Measurements in Analytical Chemistry Analytical chemistry is a quantitative science. In the process we will consider important questions, such as “How do we extract useful results from experimental data?”, “How do we ensure our results are accurate?”, “How do we obtain a representative sample?”, and “How do we select an appropriate analytical technique?” Before we consider these and other questions, we first must review some basic tools of importance to analytical chemists.
