RF value (in chromatography)The distance travelled by a given component divided by the distance travelled by the solvent front. For a given system at a known temperature, it is a characteristic of the component and can be used to identify components. How do you stain amide? A good general ...
The rf value is shorthand for the retention value of a substance. It is used in chromatography to determine the components of an unknown sample. What is the maximum and RF value can be? The maximum RF value that can be obtained is 1.0. This means that the substance travels the full dist...
Chromatography is a process for separating components of a mixture. ... The different components of the mixture travel through the stationary phase at different

(31mg, 0.3mmol) was slowly added to the flask and stirred at room temperature for 8 hours. Another 51mg of benzoyl chloride and 31mg of triethylamine were added to the flask and stirred for 24 hours. The resulting mixture was purified by chromatography to obtain (R)-hexane-M-isopropyl ...
What is the importance of Rf value in chromatography? Explain how microorganisms can be harmful or beneficial to the human body. Why is heat necessary in spore staining? How do marine microorganisms affect large-scale processes on Earth?
In chemistry, chromatography is a technique used to separate, identify, and quantify components of a mixture. All types of chromatography have a mobile phase and stationary phase which aid in the separation of the compounds. The stationary phase is normally is usually a solid or a ...
