Quantometry Lab Questions ▼
What is Base in a sample? ►
Element with the highest weight percentage in the sample.
Are there base restrictions for quantometry samples? ►
Fe, Al, Cu, Zn, Ni, Ti, Co are allowed bases.
Sample size for regular quantometry? ►
Large samples: minimum 3*3 cm² for thin samples. For thick samples, core must be 3*3 cm² × 1 cm thickness. Consult lab if cutting is limited.
Small samples: Send entire sample.
Can sample cutting be done at the center? ►
Yes, usually free. If wire cutting or time-consuming, fee applies.
Elements measurable in different bases? ►
See "Quantometry Elements Coverage" page. Consult lab if missing.
Sample amount for flake preparation? ►
15-30g recommended; up to 50g if possible.
Is non-destructive quantometry possible? ►
Yes, with surface sanding; inform during submission.
Which samples require flakes? ►
1- Cast iron parts except white cast
2- Small Fe or Ni based samples.
If minor deviation from standard occurs, is sample rejected? ►
Do not rely solely on quantometry; measure elements with precise single-element methods.
