Analytical chemistry consists of classical, wet chemical methods and modern analytical techniques. [2] [3] Classical qualitative methods use separations such as precipitation, extraction, and distillation. Identification may be based on differences in color, odor, melting point, boiling point, solubility, radioactivity or reactivity.
Hyphenated techniques are widely used in chemistry and biochemistry. A slash is sometimes used instead of hyphen, especially if the name of one of the methods contains a hyphen itself. Examples of hyphenated techniques: Gas chromatography-mass spectrometry (GC-MS) Liquid chromatography–mass spectrometry (LC-MS)
In cases with complex or unknown matrices, the standard addition method can be used. [3] In this technique, the response of the sample is measured and recorded, for example, using an electrode selective for the analyte. Then, a small volume of standard solution is added and the response is measured again. Ideally, the standard addition should ...
Coluthur Gopalan (29 November 1918 – 3 October 2019) [1] was an Indian nutritionist.He was responsible for initiating nutrition research in independent India, leading to a number of interventions such as the Integrated Child Development Services, the midday meal scheme for school children, goiter prevention programme, etc. [2] The burning feet syndrome is also known as Grierson-Gopalan syndrome.
Classical qualitative inorganic analysis is a method of analytical chemistry which seeks to find the elemental composition of inorganic compounds.It is mainly focused on detecting ions in an aqueous solution, therefore materials in other forms may need to be brought to this state before using standard methods.
Modern simultaneous CHNS combustion analyzer. Elemental analysis is a process where a sample of some material (e.g., soil, waste or drinking water, bodily fluids, minerals, chemical compounds) is analyzed for its elemental and sometimes isotopic composition.
