Answer / r.kadambavadani
In chromatography, endcapping refers to the replacement of accessible silanol groups in a bonded stationary phase by trimethylsilyl groups.
Endcapping technology prevents the tailing of a polar compound's peak and shows very high durability even with an alkaline mobile phase because of the strong film covering the stationary phase surface.
