Introduction to Chemical Analysis Chemical analysis includes any aspect of the chemical characterization of a sample material. Analytical Chemistry? “Science of Chemical Measurements”

Areas of Chemical Analysis and Questions They Answer • Quantitation: – How much of substance X is in the sample? • Detection: – Does the sample contain substance X? • Identification: – What is the identity of the substance in the sample? • Separation: – How can the species of interest be separated from the sample matrix for better quantitation and identification?

What does Chemical Analyst Do? • Analyst: Senior Analyst: Develops new measurement methods on existing principles to solve new analysis problems • Applies known measurement techniques to well defined compositional or characterization questions. • Research Analytical Chemist • Creates and /or investigates novel techniques or principles for chemical measurements. • Or Conducts fundamental studies of chemical/physical phenomena underlying chemical measurements.

What is Analytical Science? • Analytical Chemistry provides the methods and tools needed for insight into our material world…for answering four basic questions about a material sample? • What? • Where? • How much? • What arrangement, structure or form?

Classification of Analytical Methods • 1 - Qualitative analysis is what. • 2 - Quantitative analysis is how much The Role of Analytical Chemistry: applied in • Industry • Medicine • Science

An analysis involves several steps and operations which depend on: • the particular problem • your expertise • The apparatus or equipment available.
