Thin-layer chromatography is used to separate components of a plant extract, illustrating the experiment with plant pigments which gave chromatography its name. In chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components.
It is now primarily used as a teaching tool, having been replaced in the laboratory by other chromatography methods such as thin-layer chromatography (TLC). This analytic method has three components, a mobile phase, stationary phase and a support medium. The mobile phase is a solution that travels up the stationary phase by capillary action ...
Thin-layer chromatography (TLC) is a chromatography technique that separates components in non-volatile mixtures. [ 1 ] It is performed on a TLC plate made up of a non-reactive solid coated with a thin layer of adsorbent material. [ 2 ]
Size-exclusion chromatography, also known as molecular sieve chromatography, [1] is a chromatographic method in which molecules in solution are separated by their shape, and in some cases size. [2] It is usually applied to large molecules or macromolecular complexes such as proteins and industrial polymers . [ 3 ]
Column chromatography in chemistry is a chromatography method used to isolate a single chemical compound from a mixture. Chromatography is able to separate substances based on differential absorption of compounds to the adsorbent; compounds move through the column at different rates, allowing them to be separated into fractions.
The history of chromatography spans from the mid-19th century to the 21st.Chromatography, literally "color writing", [1] was used—and named— in the first decade of the 20th century, primarily for the separation of plant pigments such as chlorophyll (which is green) and carotenoids (which are orange and yellow).
There are two varieties—green and red. The stem of the Basella alba is green with green leaves and the stem of the cultivar Basella alba 'Rubra' is reddish-purple; the leaves form green and as the plant reaches maturity, older leaves will develop a purple pigment starting at the base of the leaf and work towards the end. The stem when crushed ...
Talinum fruticosum is a herbaceous perennial plant that is native to Mexico, the Caribbean, West Africa, Central America, and much of South America.Common names include Ceylon spinach, [2] waterleaf, cariru, Gbure, Surinam purslane, Philippine spinach, Florida spinach, potherb fameflower, Lagos bologi, sweetheart, and Kutu bataw in Ghana from the Akan language [1] It is widely grown in ...
