16. INTRODUCTION What Is Chemistry? - The central science (it merges into physics and biology) - The study of matter and energy and the interactions between them - The branch of the natural sciences concerned with the characteristics, composition, and transformations of matter. - Everything we hear, smell, taste, see, and touch involves chemistry and chemicals (matter)

17. INTRODUCTION Divisions - Analytical (methods of analysis of matter) - Physical (theory and concepts of chemical problems) - Organic (compounds of carbon) - Inorganic (compounds of elements other than carbon) - Biochemistry (compounds of living matter)

18. INTRODUCTION What Is Instrumental Analytical Chemistry? The use of modern automated instrumental methods for - The qualitative and quantitative characterization of matter - Identification and quantification of the constituents of matter - Studying the chemical composition of materials - Analyzing chemicals for their composition and structure

19. INTRODUCTION Why Study Instrumental Analytical Chemistry? - To understand the chemical composition of all matter - Plays important role in the pharmaceutical industry (discovery of new drugs) - Quality control of industrial manufacturing - Environmental monitoring - Biomedical applications

20. Analytical Methods - Gravimetry (based on weight) - Titrimetry (based on volume) - Electrochemical (potential, current, charge, etc) - Spectral (the use of electromagnetic radiation) - Chromatography (separation of materials) - Chemometrics (statistical treatment of data) INTRODUCTION
