Can less than 50 g of sample be measured using the bouyoucos hydrometer method of grain size analysis?
Is there a reason 50 g is always used (I only have 10 g to do this!).
If I used 10 g would this impact the measured SG value?
Would it impact the settling times used, i.e. 40 s and 2 h?
My instinct says it wouldn't but I'm uncertain.

I am not familiar with that particular equipment. Maybe I have used it and simply don't recognize the name, but my thoughts are simply that a high initial mass is to be used to ensure adequate amount of products for measurement precision concerns. I believe it is a volume measurement, correct? How precise are the increments? You need enough starting mass (volume) to make it so you can get fairly good numbers. I do not believe it is a behavior issue. More of a window of optimal precision issue.
