Thomas Cuff

Hello Roberta Sio ,

I am having a hard time understanding your question. Are you asking, what is the highest concentration of spores you can produce in a solution? Or is it the highest concentration of spores in air? Perhaps if you can explain - if it is not confidental - what you are trying to do that might help. Can you expand on your question so that the RG readers can help you find an answer?

Regards,

Tom Cuff

Roberta Sio

@Tom Cuff, thank you for identifying that my question was too vague.

I was actually asking for the highest concentration I can produce from a spore suspension.
