Overview / Applications

Outline This product is for research use only.  Do not administer it to human.


  1. On the use, pack this product into a column and wash with solvent such as hexane for Dioxins Analysis (Wako Code #083-07391 (1 L); #089-07393 (3 L)) for activation.

  2. The residual silica material should be stored in a desiccator including desiccant.

  3. Adsorption of the water of the product may decrease the activity.

  4. Be careful because this product generates heat by mixing with water.

  5. Disposal Consideration:
    Cautiously add to a large stirred excess of water.  Adjusting the pH to neutral, separate any insoluble solids or liquids and package them for hazardous-waste disposal. Flush the aqueous solutions down the drain with plenty of water.

  6. On handling, wear protectors as impervious gloves, safety glasses and a mask due to its toxicity.

  7. First Aid Measures:

  8. Skin Contact: Remove contaminated clothes and shoes, rinse skin with plenty of water or shower. Use soap to help assure removal.  If irritation persists, transport to a hospital immediately.
    Eye Contact: Remove any contact lenses at once.  Flush eyes well with flooding amounts of running water for at least 15 minutes and wash them with 1~3% Sodium Bicarbonate solution.  Assure adequate flushing by separating the eyelids with sterile fingers.  If irritation persists, transport to a hospital immediately.
