Iupac definition of chromatography?
"Chromatography is a physical method of separation in which the components to be separated are distributed between two phases, one of which is stationary while the other moves in a definite direction."
Why can't polymers be analysed by gas chromatography?
polymers are not volatile.. therefore, can't be separated by Gas Chromatography
What type of species can be separated by HPLC but not by gas liquid chromatography?
mixture of enantiomers can be separated by HPLC
What kind of species can be separated by high performance liquid chromatography but not gas chromatography?
HPLC can separate nonvolatile species and GC cannot.
What is separation in chromatography?
two liquids having different solubility are separated by chromography.
Why is alcohol used when testing to see if chlorophyll is needed for photosynthesis?
Chlorophyll dissolves (becomes mobilized) in alcohol. Once mobilized, it can be separated from the other pigments by chromatography.

What are disadvatages of chromatograph?
chromatography has many varieties -paper chromatography, sometime complexe mixtures cant be separated, TLC plates do not have long stationary phases -gaz chromatography: the molecule should be volatile -Chiral Chromatography can be expensive - Ion Exchange or Ion Chromatography: Turbidity should be low below 10ppm -Size Exclusion Chromatography: low resolution technique which gives few peaks and requires large differences in molecular weight for resolution -Gel chromatography: the target protein frequently becomes an abundant substrate for proteases that may also be present in the mixture. Another disadvantage is low sample handling.
