what does analytical chemistry do

Analytical chemists use a variety of analytical instruments to carry out their work. Common instruments include gas and liquid chromatography as well as spectroscopy and ion-chromatography. These analytical instruments require calibration to ensure that the results are accurate.

Analytical chemistry techniques can be used to analyze matter quantitatively and qualitatively. These techniques are used in forensics and environmental science, medicine, food science, and medicine. Analytical Chemistry is used to identify substances, measure their concentrations, detect pollutants and analyze chemical reactions.Early analytical chemistry techniques included simple spectrometric techniques. Later, spectrometric techniques were improved. NMR is the most commonly used analytical chemistry technique today. It is used to study structure of molecules.Another technique is spectroscopy which can be used to detect chemical compounds. Spectroscopy is the process of exposing a compound infrared light. The resulting absorption spectrum can be used to identify the functional groups of the compound.Chromatography is another technique that separates mixtures. Different instrumental methods are used in chromatography, including field-flow fractionation or electrophoresis. These methods can be used to determine the concentration of the mixture as well as the chemical reaction that created it.Colorimetry, titration and potentiometry are all other analytical chemistry methods. These methods can be used to measure the solution's concentration, volume, and property.

In modern analytical chemistry, a scientist uses advanced equipment to determine the chemical composition of a substance. They use spectroscopy, electrochemical and separation techniques. These methods feature high sensitivity, accuracy, and precision.
