Homework Statement




Heres the question asked:


Consider the above FIA apparatus. Calculate the Dmax (as seen by the detector) for the apparatus assuming that a 300uL injection volume results in no dilution (dispersion) of the injected sample by the sample stream line in this system.

I know you guys can't see the apparatus picture , but i just want to know the right formula to use or someone to lead me to the right direction. Cant find anything in my lecture notes.



Thanks in advance.

Perhaps just a simple mass balance (as in dilution & mixing) will suffice. But that's just a stab in the dark.
