What is analytical chemistry?

Analytical chemistry approaches can be applied to a variety of fields, including the food industry.

Analytical chemistry is the study of matter to reveal its composition, structure, and extent. As these understandings are fundamental in almost all chemical research, this field is used to obtain information, ensure safety, and solve problems in many different chemical areas, and is essential in both theoretical and applied chemistry.

Analytical chemistry approaches can be applied to the pharmaceutical industry.

Early analytical chemistry focused primarily on identifying elements and compounds and discovering their attributes. The discovery gave way to systematic analysis, which took a giant step forward with the invention, in the 1850s, of the first instrument for chemical analysis – flame emissive spectrometry – by Robert Bunsen, a German chemist best known for his invention of the Bunsen burner. , and his colleague Gustav Kirchoff, a German physicist known for coining in 1862 the name “black body” radiation for an object that absorbs all the electromagnetic radiation that hits it.

Analytical chemists can use robotics in their analysis.

Other separation processes were developed, including various types of chromatography, such as paper, gas, and liquid; electrophoresis; crystallography; microfiltration; and other spectrometers, including atomic absorption spectrometers, infrared spectrometers, and mass spectrometers. Other changes took place in the field, for example, the extension of analytical chemistry, allowing the development of bioanalytical chemistry. Bioanalytics includes areas such as genomics, lipidomics, metabolomics, peptidomics, proteomics and transcriptomics.

Analytical chemists may use digital microscopes during their analyses.

Traditional subdivisions of analytical chemistry followed the same paradigm as statistical analysis: a qualitative approach that focused on determining which elements and/or compounds were present, and a quantitative approach that aimed to establish the precise amount of an element or compound in a given sample. Either or both approaches can be applied to materials in a variety of fields, including the food and beverage industry, the pharmaceutical industry, synthetic materials such as polymers, and natural materials such as minerals and water samples. As the field has grown, analytical chemistry has also broadened to embrace the applications of its techniques in forensic and forensic medicine.

Analytical chemists examine chemicals to ensure consistent lab work.

Analytical chemists today use a wide variety of techniques in their analysis, including some involving robotics, digital microscopes, Fourier transform infrared spectrophotometers, chip-based technology, and chemometrics, for example. They also use techniques in which technologies are combined, resulting in approaches known as hyphenated or hybrid techniques, characteristically referred to as initials. Examples include CE-MS — capillary electrophoresis-mass spectrometry; GC-MS — gas chromatography-mass spectrometry; CE-UV — ultraviolet capillary electrophoresis; and HPLC / ESI-MS – high performance liquid chromatography / electrospray ionization – mass spectrometry.
