Figure 2: Typical densitograms of a solution containing diclofenac sodium using a mobile phase containing toluene:methanol (20:10 v/v), saturation time of 20 min using 5 cm×10 cm TLC silica gel 60 F254 plate and application volume was 5 μL at a detection wave length of 284 nm. Where track 1: Blank/methanol and track 2: diclofenac sodium (0.1 mg/mL), Rf 0.55.
