[RASMB] high/low s m

[Ariel Lustig]

Dear colleagues,
 ( a tip !) in case of fast sedimenting particles in aqueous solution , it is  possible to exchange  (partly) the water with  D2O , so ( depending  on  the  Vbar  of  the particle) the apperent  s' and m will  be reduced  
and can be recalculated  to water when when the k faktor D2O/H2O is respected. Due to hydration of the  
particle adding sucrose or salt  to rise the  solvent  density should  be  avoided.
Under 2000 rpm hard to avoid the processing of the rotor. meniscii become  broader.
                                                                                                                        ariel
