Can I measure organic matter content of sediments, by LOI, after freeze drying

Recommended Posts



I am running an experiment and I want to measure the water content and organic matter content of my sediment cores. I am currently working as a research visitor and the lab I am at does not have access to an oven or muffle furnace. The manager has suggested I freeze dry the samples to measure water content. Could I then transport the freeze dried sediment samples back to my home land and measure the organic matter content through Loss-on-ignition? Or will the freeze dryer process interfere with the organic matter content?
