Questions

1–3 of 3 Questions  

  1. is it possible to know the molecoar weight to calculate the molarity of the suspension?

    1 answer

    1. Unfortunately, the molecular weight of this product is not determined.

      Helpful?

  2. How did you verify the amine coating? What spectroscopy method have you used to verify the amine coating? Can you show the result that proves that the amine has been coated? (For example, if you have done FTIR, then can you show us the peaks)

    1 answer

    1. The amine modification of these beads is validated through an extensive series of titrations. Unfortunately, the method is considered proprietary. There is no specific documentation or data available to share.

      Helpful?

  3. what is the concentration of polystyrene microplastic [mg/ml] in this product No. L9904

    1 answer

    1. The concentration of this aqueous suspension is 2.5% w/v or 2.5g/100 mL. This equates to 25mg per 1 mL package.
