Why do we need GC instead of HPLC? or Why do we need HPLC
instead of GC?

Answer Posted / punnitharaja

Gc analyze only for residual solvents means here using
flame ionization detector at a time so many solvents
analyzing temperature program also here.HPLC at a time not
using so many solvents because here column using polar or
non polar but GC using like midpolar also. Main reason is
dissolving process in mobile phase because polar and
nonpolar nature
