Hi all!

I am planning to dry some organic samples (calcium carbonate + unkonwn amount of organics ~20mg) in order to remove the water content before gravimetrich analysis.

So I was wondering if there is a standard way of drying in a controlled way small amounts of powder, to 1) remove the water content and 2) don't burn off any organics within the sample.

I was thinking to dry them in a convexion oven at just 45°C fro 48h but I am not sure if it would be ok.

Thank you so much!
