  • What happens if DMPD is mixed with ferric iron?
  • Normally, excess of DMPD with limiting concentration of ferric iron brings a reproducible result. If the solution is mixed with any antioxidant molecules (e.g., Trolox, ascorbic acid), the Fe (III) iron gets converted to Fe (II) iron and the color gets reduced.
  • How to prepare DMPD standard curve?
  • DMPD stock solution (1 ml) was added to 100 ml of acetate buffer (0.1 M, pH 5.25) to bring the DMPD concentration to 1 mM as working. A ferric chloride standard curve was prepared by taking 0.020 to 0.20 mM ferric chloride as the final concentration in 2 ml solutions (1.9 ml of DMPD solution with 100 μl ferric chloride solutions accordingly).
  • What is modified DMPD method?
  • The modified DMPD method proposed by us measures with great accuracy the oxidant potential of plasma, using the oxidizing effect of plasma to oxidize DMPD into producing a stable pink color that obeys the Beer–Lambert law at 505 nm. The method is fast and reproducible.
