Analytical Chemistry is the science of obtaining, processing, and communicating information about the composition and structure of matter. In other word, it is the art and science of determining what is and how much of it exists. Analytical chemistry is a branch of chemistry which deals with analysis of chemical substances of all sorts. The importance of it is due to its ability to check the quality of foods, drugs and other chemicals which we use in daily life. Without it, it would be impossible to keep up strict norms and the safety with use of chemicals.
four basic questions about a material sample?
What?
Where?
How much?

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?
