I plan to use a mortar and pestle to grind my fish and zooplankton
tissues (for del13C and del15N analysis), but I have a question
regarding the type of mortar and pestle to use. Can I use porcelain?
Or should I use marble or glass? I am concerned that the porcelain may
grind with and conaminate my samples. Thanks!
