Compare and contrast Column (solid-liquid) chromatography, Paper
Chromatography, and thin layer chromatography in respect to the
size of the sample that can be separated, the ease of use, and the
versatility of the method.
Compare the advantages and limitations of column chromatography
with those of thin-layer and gas chromatography. Discuss all 3
chromatography methods. When you would use them and in which case
is each useful and not useful?
Describe the following 3 types of chromatography: thin-layer
chromatography, flash column chromatography, and gas
chromatography. For each type describe the scale (how much compound
can be used), the utility and describe the 2 phases that correspond
with that type of chromatography.
2. what is necessary for separation using chromatography
3. what is normal phase and reverse phase chromatography
if you could link me a video so i could learn I will add
points.
Thin Layer Chromatography utilizes a glass or metal plate coated
with a thin layer of absorbent material such as silica gel. The
sample is prepared similiarto paper chromatography and a solvent is
used to elute the sample.
1. Which is the stationary phase? Plate Silica
Gel Solvent
2. Which is the mobile phase? Plate Silica
Gel Solvent
3. Which component is inert? Plate Silica
Gel Solvent
Explain thin layer chromatography and its utility in determining
the components of a mixture. Be sure to briefly explain how TLC
works as well as what and how the visualization techniques
work.
