ANSWER

The field Pre-Column Volume tells the 2695 Separations Module to start the gradient and delivers this volume before making an injection.  Use this parameter when transferring a method from a system that has a delay volume smaller than that of the 2695 Separations Module.  This parameter can also be used to reduce the delay volume of the 2695 Separations Module for narrow or microbore columns, because the sample is held in the sample loop (if desired) until the gradient front reaches the sample loop.
