The amount of silica dissolved is a function of time and acid concentration. For short periods of time (1 to 40 hours) a maximum amount of silica is dissolved in about 0.8 N HNO 3. For long periods of time this maximum is at 0.1 N or less.

DNA separation by silica adsorption - Wikipedia

The DNA can then be washed with high salt and ethanol, and ultimately eluted with low salt. After the DNA is adsorbed to the silica surface, all other molecules pass through the column. Most likely, these molecules are sent to a waste section on the chip, which can then be closed off using a gated channel or a pressure- or voltage-controlled chamber.Material Safety Data Sheet - Brownell Limited,Silica (synthetic, amorphous): - OSHA Permissible Exposure Limit (PEL) - - 80% (SiO 2) mg/m3 (TWA) for amorphous silica, including natural diatomaceous earth. - ACGIH Threshold Limit Value (TLV) - 10 mg/m3 (TWA) for amorphous precipitated silica and amorphous silica gel.
