|
Thin Layer Chromatography |
| |
|
Silica gel with calcium sulphate (CaSO4 ½
H2O) as binder is by far the most
extensively used adsorbent in Thin Layer
Chromatography because of the excellent
separation it affords. When coated on a
plate in the form of thin layer it serves as
a versatile solid stationary phase for
adsorption and partition chromatography. |
