What is chromatography Mcq?
Chromatography is a separation technique in which the complex mixture are separated into two phases: a stationary phase with a large surface area, and a mobile phase. The goal of the stationary phase is to delay the passage of the sample components.
Which force is involved in the chromatography Mcq?
Explanation: In Column chromatography, the stationary phase held in a narrow tube and the mobile phase is forced through it under pressure.
What is the principle of paper chromatography Mcq?
Clarification: The principle involved in paper chromatography is partition chromatography where the substances are partitioned between liquid phases. One phase is the mobile phase water which moves over the paper and other is the water which is held in the pores of the filter paper used. 2.
What are the 3 types of chromatography testing?
While this method is so accurate, there are primarily four different types of chromatography: gas chromatography, high-performance liquid chromatography, thin-layer chromatography, and paper chromatography. Each has its own advantages and benefits in several industries, from healthcare to forensic science.
What are the different types of chromatography?
Types of chromatography
- Column chromatography.
- Ion-exchange chromatography.
- Gel-permeation (molecular sieve) chromatography.
- Affinity chromatography.
- Paper chromatography.
- Thin-layer chromatography.
- Gas chromatography.
- Dye-ligand chromatography.
Which force is involved in chromatography?
The four forces involved in chromatography are the London dispersion, dipole-dipole, hydrogen bonding and ion-dipole forces.
What is eluent Mcq?
Eluent :- It is a solvent that used for separation of absorbed material from stationary phase. Eluate :- is a liquid solution that is a result from Elution. Chromatogram :- It is a graphical represention of Chromatography.
What is Rf value?
In thin-layer chromatography, the retention factor (Rf) is used to compare and help identify compounds. The Rf value of a compound is equal to the distance traveled by the compound divided by the distance traveled by the solvent front (both measured from the origin).
