What is the principle involved in extraction?
Extraction is based on the principle of transferring a substance from one phase to another, typically from a solid or liquid phase to a liquid phase. This is achieved by using a solvent that selectively dissolves the desired substance while leaving impurities behind. The goal of extraction is to separate the desired compound from a mixture.
What is a definition of chromatography?
It is a technique based on the general principle of distributing components of a mixture between stationary and mobile phase.
What is the basic physical principle that chromatography is based upon?
The principle behind Chromatography is :The rate of migration of the solute depends upon the rate of interaction of the solute with the two phases, one being the mobile phase and the other stationary phase as the compounds travel through the supporting medium.
What is the principle behind normal phase chromatography and how is it used in separating compounds?
Normal phase chromatography separates compounds based on their polarity. In this method, the stationary phase is polar (such as silica gel) and the mobile phase is nonpolar. Compounds with higher polarity interact more strongly with the stationary phase, causing them to move more slowly through the column and separate from less polar compounds.
How does chromatography separate molecules?
The principle is based on equilibrium of the molecules between the mobile phase and the stationary phase. This will vary depending on the polarity of the substance, and the two phases. If the substance in more soluble in the mobile phase, it will travel further, and vice versa.
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
Solution based on the phase of the white gold?
The based on the phase of the white gold, it is " Pure Solid White gold Formula" !
What is state phase rule?
The phase rule is a principle in physical chemistry that relates the number of phases, components, and degrees of freedom in a system at equilibrium. It helps to predict the number of coexisting phases in a system based on its degrees of freedom and components.
What is the principle of interference?
The relationship is interference is the addition of two or more wave pattern and the principle of superposition is the displacement of any point due to the superposition of wave system equal to the sum of the displacements of the individual waves at that point.
Can a single phase inverter's working principle can be explained?
in single phase inverter we use two chopper the ratio of output ac to the ratio of input dc
What is the principle of GC?
Gas chromatography (GC) separates and analyzes compounds based on their distribution between a stationary phase (inside a column) and a mobile phase (a carrier gas). Compounds with different affinities for the stationary phase will travel through the column at different rates, allowing for their separation. The detector at the end of the column detects these compounds based on their unique retention times.
What are the key differences between normal phase and reverse phase chromatography techniques?
Normal phase chromatography separates compounds based on their polarity, with the stationary phase being polar and the mobile phase being nonpolar. Reverse phase chromatography, on the other hand, separates compounds based on their hydrophobicity, with the stationary phase being nonpolar and the mobile phase being polar.
