Hi All:

        I'm trying to homogenize 30 cm long cattail samples (the leaf portion, not
the main stalk)) into a fine powder for d15N and d13C analysis.  I had some
luck with a ball mill but the rubber/cork gaskets are breaking down and
contaminating the sample.  The material is quite fibrous which makes
homogenization difficult.

        Any advice would be appreciate.  Please e-mail me direct.  Thanks in advance.

Jeff
