Analytical Chemistry is an applied branch of chemistry that concerns with the study of chemical composition of materials in terms of composition and how much quantity of each component is present. It proved indispensable to our understanding of basic branches of chemistry, such as, organic, inorganic, physical and biochemistry. The analytical techniques have made possible understanding of matter ranging from atoms to the complex molecular structures of materials .Analytical Chemistry has been used for studies on diverse materials ranging from naturally occurring materials, synthetic materials, ocean bed surveys to studies on extra-terristrial matter. Evaluation of Impact on environment through human activities would not have been possible without resorting to analytical techniques.
Traditionally analytical chemistry aims to study a material through qualitative and quantitative methods. Qualitative analysis confirms the presence of a particular element or a compound or a particular functional group in a sample. Quantitative analysis is subsequently used to determine the quantity of the element or compound in a sample.
Modern Analytical Techniques
Advances in instrumentation and computers have made significant growth possible in analytical sciences. This has made possible studies of complex structures of materials in diverse areas such as nanotechnology, polymers, biotechnology, industrial, forensics, and environmental monitoring.Analytical chemistry research is largely driven by performance (notably sensitivity, selectivity, ruggedness, large linear range, precision, speed and cost ) considerations. Notably advances have been witnessed in chromatographic techniques, spectroscopic analysis, electrochemical methods thermal methods of analysis and ultra trace metal analysis in different matrices. Combination techniques utilizing two or more instruments also known as hyphenated techniques, such as LC-MS, GC-MS, ICP-MS,etc have also made significant contribution to our understanding of the nature of materials through manifold improvement in resolution and detection at extremely low levels.
