Question

which among the following is not an example of planar chromatographic technique?
1 ) HPTLC
2) HPLC
3) TLC
4) circular paper chromatography
​

Answer 1

HPLC is not an example of planar chromatographic technique so option (2) is the correct one.

• Because High-Performance Liquid Chromatography (HPLC) is an aspect of column chromatography that pumps a sample combination or is analysed in a solvent and this solvent is the mobile phase, at the high pressure through a column with chromatographic filling material (stationary phase).
• There are two major portions of planar chromatography: paper chromatography and thin-layer chromatography (TLC). Although both techniques pursue relatively identical principles and procedures, they use various substances as beds or planes for the static stage of the procedure.
