Why must the chromatography chamber be closed tightly?
so that the atmosphere in the jar becomes saturated with solvent.
What is the purpose of the filter paper inside the developing chamber in chromatography?
Paper is the (solid) stationary phase, 'sucking' up the liquid, mobile (= transporting) phase
The relative vapor pressures of the mixture components are important in GC Gas Chromatography but not in LC Liquid Chromatography Why is that?
In Gas Chromatography, before you can correctly separate and identify the components, you need to vapourise the mixture first. How fast a substance vaporises is dependent on their vapour pressure. In Liquid Chromatography, there is no need to vapourise the mixture and hence vapour pressure is not important here.
What are the different types of chromatography?
there are different types like gas chrom. and thinlayer chrom Answer: There are two types of chromatography:liquid chromatography gas chromatography
Calibration of gas chromatography?
What is the precedure for calibration of gas chromatography? How calibration is perform for gas chromatography? What is the precedure for calibration of gas chromatography? How calibration is perform for gas chromatography?

Why there is a need for chromatography in our daily life?
it is cool
Is saturate fat good for you?
you need it in your body to live, so it is good for you.

Why solvent is used in Paper chromatography?
In chromatography you need one stationery phase (paper) and one mobile phase (here solvent, moving by capillary forces)
Another word for saturate?
Synonyms for "saturate" : permeate, pervade, imbue, or soak.
What are 3 types of chromatography?
1. thin -layer chromatography 2. gas chromatography 3. liquid chromatography
Calibration of gas chromatography?
What is the precedure for calibration of gas chromatography? How calibration is perform for gas chromatography? What is the precedure for calibration of gas chromatography? How calibration is perform for gas chromatography?
What is grass chromatography?
There is no such thing as grass chromatography. there is only High Performance Liquid Chromatography, Gas Chomatography, and Paper Chromatography.
What would you use in a paper chromatography?
We use several things such as stationary phase which is a paper, mobile phase according to your solute and the mixture to be analysed. All these are placed in a closed chamber.
