Analytical chemistry is solely the study of composition of chemical substances constituting both natural and artificial material matter. Analytical chemistry is not specific to any particular reactions or compounds unlike other sub-fields of chemistry for instance, inorganic or organic chemistry. The aspects of chemical substances studied in analytical chemistry include the features like species identity and composition and also geometric features for example, distributions of species and molecular morphologies. Analytical chemistry has ion recent years gained much importance as it not only aids in development of new theories and concepts of pure science but also establishes a broad range of practical applications in applied sciences such as environmental monitoring, biomedical applications, forensic sciences and also for quality control in industrial manufacturing. Analytical chemistry seeks to clarify chemical compositions by means of developing tools. Analytical chemistry utilizes similar experimental tools used in experimental physical chemistry.

Most analytical chemistry term papers tend to focus upon modern applications and theories in this sub-field of chemistry in which is dominated by instrumental study. Research papers pertaining to analytical chemistry either require knowledge upon new applications and findings or may require students to demonstrate their knowledge about new methods. For instance, research papers pertain to ask about the improvements made by the use of tunable laser in the specificity of the spectrometric method. All analytical chemistry term and research papers are significantly written in ACS style but in some cases different writing styles such as CSE/CBE Style may also be used based upon word length requirements.
