Overview of analytical chemistry Chemistry 321, Summer 2014

Introduction to Quantitative Analysis Qualitative Analysis: What is it? (you did this in o-chem lab) Quantitative Analysis: How much is there of it? (e.g., mass, concentration)

Vocabulary of analytical chemistry The sample contains: Analyte – species of interest Matrix – solvent, other species The matrix often interferes with measuring the analyte

Define (or refine) the goal of the analysis: What is this system’s chemical composition? Obtain a representative sample Make analytical measurements
