____________________ Is the Volume Between the Point at Which the Solvents

____________________ is the volume between the point at which the solvents are mixed and the beginning of the column.Which is NOT true for dwell volume and dwell time?

A) If the dwell time is 5 minutes,a solvent change initiated at 9 minutes does not reach the column until 14 minutes.
B) A difference in dwell volumes is the main reason why gradient separations do not always transfer well between instruments.
C) Dwell volume is the volume between where solvents are mixed and the beginning of the column.
D) The product of the dwell volume and the flow rate is the dwell time.
E) It is helpful to indicate the dwell volume when reporting a gradient separation.
