[RASMB] SEDANAL question

[Walter Stafford]

Question: which "scaling parameters" are you referring to? and which parameter is entered as 9 mls/gram. NOTE: The mass concentration units used by SEDANAL are  L/g, not mL/g.

So if you entered "9", you should try 0.009 (units are L/g)

This also was true if the initial guesses varied significantly from a value of 9mls/gram.
