| Analytical chemistry spans nearly all areas of chemistry but involves the development of tools and methods to measure physical properties of substances and apply those techniques to the identification of their presence (qualitative analysis) and quantify the amount present (quantitative analysis) of species in a wide variety of settings.

Qualitative Analysis One of the two key aspects of analytical chemistry is the ability to use techniques/measurements to provide useful information about an unknown sample that can by used to identify the sample. This may or may not be accomplished via the application of instrumental technology.
| Quantitative Analysis One of the two key aspects of analytical chemistry is the ability to use techniques and measurements to provide useful information about a sample that can by used to quantify the sample. This may or may not be accomplished via the application of instrumental technology. |
Instrumental Analysis Modern day analytical chemistry is performed with the aid of instruments, often of significant complexity. Consequentially, direct investigation of how these instruments operate is important.
| Electrochemistry The married subjects of thermodynamics and equilibrium will be expanded to a troika by including electrochemistry. The ability to "steal" and "donate" electrons will be introduced and discussed in the context of free energies, enthalpies, entropies and equilibrium constants. |
Microscopy Light can be used in different fashions. It can be used as a spectroscopy to identify either time- or frequency resolved signals that directly map to the microscopy, often quantum mechanical nature of the studies samples. It can also be used to characterize the topological surface of materials via the field of microscopy. The merging of the two fields is a topic of great interest currently.
| Spectroscopy Spectroscopy is the study of the absorption and emission of electromagnetic radiation by matter. Spectroscopy is an important tool that can be used to find the molecular structures, composition, and vibration frequencies of a substance. It can also be used to find the concentrations of reactants as functions of time to find the reaction intermediates. The defining characteristic of spectroscopy is interaction of light (electromagnetic spectrum) and matter. Knowledge of both is required to fully interpret the measured data.
