What is the procedure for protein precipitation by zinc sulphate for LC-MS analysis? Please response if any one has done it.
Google for "Carrez solutions". We often use them mostly for HPLC sample preparation. Carrez II contains zinc sulphate. Together with Carrez I it forms a precipitate to which high-molecular weight stuff adsorb.

You can buy Carrez solutions premade, or make them yourself.
