Dwell Volume of the Pump

Page 222
The gradient delay volume of an HPLC system is defined as the volume
of the entire flow path between the point where the gradient is formed
and the point where the mobile phase enters the column (see
Delay Volume, Dwell Volume and Ripple
The pump contributes to the system gradient delay volume by the dwell
volume, which is the calculated volume between the point where the
gradient is formed and the pump outlet.
