CHROMATOGRAPHIC Meaning and
Definition
-
Chromatographic refers to a scientific technique used for the separation and identification of chemical compounds. It involves the use of a chromatographic system, which consists of a stationary phase and a mobile phase. The stationary phase is a material that supports or absorbs the analyte, while the mobile phase carries the sample through the system.
In chromatographic analysis, the mixture being tested is dissolved in the mobile phase, which then carries it through the stationary phase. As the sample moves through the system, different compounds within the mixture interact with both phases to varying extents. This differential interaction leads to separation of the components based on their chemical properties, such as size, polarity, or affinity.
Chromatographic techniques can be classified into different types, such as gas chromatography (GC) or liquid chromatography (LC), depending on the nature of the mobile phase used. GC uses a gaseous mobile phase, while LC uses a liquid mobile phase. Within each type, various methods and columns can be employed to achieve specific separation goals.
The term chromatographic is derived from the Greek words "chroma," which means color, and "graphein," which means to write or record. This origin is rooted in the initial use of chromatographic techniques to separate and identify colored compounds. However, modern chromatography has expanded its applications to a wide range of fields, such as pharmaceuticals, forensics, environmental analysis, and food science, making it an indispensable tool in chemical analysis and research.
Common Misspellings for CHROMATOGRAPHIC
Etymology of CHROMATOGRAPHIC
The word chromatographic is derived from two Greek roots: chroma, meaning color, and grapho, meaning to write or draw. The term chromatography was first coined in 1906 by Russian botanist Mikhail Tsvet, who used it to describe a technique for separating and analyzing plant pigments based on their different colors. Combining the Greek roots, chromatographic essentially means related to the separation or study of colors.
