• Chromatography has been a fundamental technique used for chemical separation. Specifically, column chromatography, typically taught in introductory organic chemistry laboratories. This situation runs contrary to the principles of responsible chemical and waste management emphasized by the green chemistry movement. • Chromatographic techniques have significant role in natural products chemistry as well as contribute dramatically in the discovery of novel and innovative compounds of pharmaceutical and biomedical importance. • This study focused on step-by-step visual demonstration of fractionation and isolation of biologically active plant secondary metabolites using column-chromatographic techniques.

Pregnancy detection kits are diagnostic products that check for chemical markers related to pregnancy. These kits take up the midstream format, which is one of the three categories under rapid pregnancy tests. The remaining two are the strip format and the card or cassette format. A pregnancy detection kit uses rapid chromatographic immunoassay technique for the detection of hCG in urine to indicate pregnancy.

It is a process of separating component(s) from the given crude drug by using a gaseous mobile phase.” It involves a sample being vaporized and injected onto the head of the chromatographic column. The sample is transported through the column by the flow of inert, gaseous mobile phase. The column itself contains a liquid stationary phase which is adsorbed onto the surface of an inert solid.

The segments of plants that have medicinal value and mending properties are called as bioactive compounds and they experience a progression of the procedure called as Extraction, Isolation, and Characterization. Column Chromatography strategy for plant removes is one such method for confining and distinguishing the bioactive compounds utilizing a stationary stage, for example, Silica gel or Alumina. The Development of logical strategies needs to prompt a subjective and in addition quantitative examination of Isolation of bioactive compounds from Plants which are herbs with a muddled arrangement of blends framed through different pathways.

Introduction to chromatography tecniques

This report categorizes the market into two broad segments, namely, chromatography systems and consumables. The market comprises liquid, gas, supercritical fluid, thin layer chromatography systems, and other components of systems (detectors, autosamplers, pumps, fraction collectors, and others). The liquid chromatography (LC) systems hold the largest share of 69% of the overall chromatography market in 2013. The high share of LC systems in this market is attributed to the large scale application of HPLC systems and the rising use of UHPLC systems.
