Cleaning Procedures for Silicon Wafers INRF application note Process name: SOLVENTCLEAN + RCA01 + HFDIP . not wet it. Since oxide is hydrophilic and pure silicon is hydrophobic, a non-wetting surface is clean of oxides. Blow dry with nitrogen and store in a clean, dry environment. The 2% solution may be saved for other cleaning.
That means that it must adsorb more strongly to the silica gel or alumina than the yellow one. The less polar yellow one spends more of its time in the solvent and therefore washes through the column much faster. The process of washing a compound through a column using a solvent is known as elution. The solvent is sometimes known as the eluent.
