1. Sample requirements: (If the amount of sample is insufficient, the accuracy of the result cannot be guaranteed, and we do NOT offer Free re-testing.)

1) For bulk/film sample: length/width/thickness < 5 mm.

2) For powder sample:

  • If SSA>500 m2/g, please provide >100 mg.
  • If SSA<100 m2/g, please provide >200 mg.
  • If SSA<10 m2/g, please provide >0.5~1 g.
  • You can also use this formula to determine the required weight per sample.

Sample Weight (g) = 15 / SSA

3) If you do not know SSA, please prepare the sample based on the list below.
