Normal phase chromatography is a type of chromatographic technique used in analytical chemistry to separate and analyze compounds based on their polarity. In this method, a polar stationary phase, such as silica gel, is used along with a less polar mobile phase, such as a nonpolar solvent. The compounds in the sample interact differently with the stationary and mobile phases, leading to their separation based on their polarity. This technique is commonly used to analyze organic compounds, such as natural products and pharmaceuticals, in research and quality control laboratories.

What are the key differences between reverse phase chromatography and normal phase chromatography?
Reverse phase chromatography and normal phase chromatography are two types of chromatographic techniques that differ in the polarity of the stationary phase and mobile phase. In reverse phase chromatography, the stationary phase is nonpolar and the mobile phase is polar, while in normal phase chromatography, the stationary phase is polar and the mobile phase is nonpolar. This difference in polarity affects the retention and separation of compounds in the sample being analyzed.

What is normal and reverse chromatography?
normal chromatography based on polarity and non polarity principle If mobile phase is polar, compound is non polar,then non polar compound first elutes as peak and then followed by polar compound reverse chromatography is if the mobile phase is polar, the polar compound first elutes and then followed by non polar compound

How is chromatography a analytical tool?
Chromatography is an analytical tool used to separate and analyze complex mixtures. It works based on the principle that different components in a mixture will move at different rates through a stationary phase when subjected to a mobile phase. By analyzing the resulting separation pattern, chromatography can provide valuable information about the composition and identity of the mixture being analyzed.
