Summary
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.
Product Features
Ball Grinding at -196 °C
The CDS Analytical's cryo-mill adopts ball grinding technique and allows the sample to be pre-cooled by liquid nitrogen to -196 °C
High Throughput
The cryo-mill supports up to 4 sample jars. Each sample jar could host up to 5 grams of sample.
Vertical Oscillation
The cryo-mill could generate up to 70 Hz oscillation on the sample jar vertically to bring strong impact for effective sample grinding.
5 micron Final Fineness
The sample jar could accommodate sample size less than 8 mm in diameter, and yield a final fineness up to 5 micron.
Built-in Method
The cryo-mill has a user-friendly interface with built-in method designed for Py-GC-MS applications.
Safety First
The cryo-mill has multiple safety features built-in, including an automated locking mechanism when the cryo-mill is not balanced.
