A distinct advantage of analytical pyrolysis GC-MS (PY-GC-MS) in polymer analysis is a simplified sample preparation process by skipping the solvent extraction and concentration step. However, the challenging hurdle in the sample preparation for PY-GCMS is to homogenize the polymer samples, which would determine the reproducibility of the following sample runs. As the rule of thumb for PY-GC-MS, more homogenized samples would yield more reproducible data. Among various homogenizers, cryogenic ball mill has been proven to be a powerful tool in homogenizing thermally sensitive and elastic polymers. CDS Analytical has designed an economical and ready-to-use cryo-mill solution for such applications.
