What do you mean by chromatography?
Chromatography is a process for separating components of a mixture. The different components of the mixture travel through the stationary phase at different speeds, causing them to separate from one another.
What is the method of sublimation?
Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid phase.
What material is chromatography?
In paper chromatography support material consists of a layer of cellulose highly saturated with water. In this method a thick filter paper comprised the support, and water drops settled in its pores made up the stationary “liquid phase.” Mobile phase consists of an appropriate fluid placed in a developing tank.
What is sublimation and example?
sublimation, in physics, conversion of a substance from the solid to the gaseous state without its becoming liquid. An example is the vaporization of frozen carbon dioxide (dry ice) at ordinary atmospheric pressure and temperature. The phenomenon is the result of vapour pressure and temperature relationships.
What is sublimation and distillation?
Distillation: Distillation is a method of separating mixtures based on differences in volatilitilies of components in a boiling liquid mixture. Sublimation : Sublimation is the process of transition of a substance from the solid phase to the gas phase without passing through an intermediate liquid phase .
What are the 3 main types of chromatography?
The chromatography techniques are: 1. Paper Chromatography 2. Thin Layer Chromatography and 3. Column Chromatography.
What is mobile phase HPLC?
The solvent used to separate components in a liquid sample for HPLC analysis is called the mobile phase. The mobile phase is delivered to a separation column, otherwise known as the stationary phase, and then to the detector at a stable flow rate controlled by the solvent delivery pump.
