  • Q:

    When grinding a fingernail or toenail sample for the purpose of trace-element analysis, to what extent is the sample contaminated by the grinder--particularly for elements such as Fe, Cr, Mn, Cu, Zn, Ni?
    Asked on 1/15/2013 by Steve from University of Missouri, Research Reactor

    1 answer



      The grinder and blades are made from 304SS which has a hardness of 5 Mohs, twice that of typical nails (2.5 Mohs). We do not have any information on trace amount of ions that would then be transferred to the sample. I found the following link to provide information on the composition of 304SS and the min and max levels of the composition elements expected.
      This may help if you are seeing any cross contamination on the analytical level.

      0.004" is the smallest setting and will give 0.004" particles.

      Setting the unit at 0.004" will give 0.004" results.

  • Q:

    How much sample can you put into one of these? What hardness is this appropriate for?

    Thank you!

      There is no specification available for the volume that can be loaded into the mill. The diameter of the milling head is .625”, and the space between the head and the milling surface is set from the factory at .004”, but it can be adjusted by loosening the set screw to approximately .5”.
      This grinder was designed to grind finger/toe nails (2.5 Mohs). The whole unit is composed of 304SS and it is suggested that nothing with a hardness greater than 5 Mohs should be used in this unit.
