Gradient performance

Introduction
This section contains information on how the system can be configured to develop
gradients using feedback loop technology.

Gradient performance

ÄKTAprocess can be configured to develop gradients at any flow rate using feedback
loop technology with an accuracy better than ± 2% within the operating range (see GS
in the product documentation package). The illustration below shows the programmed
(blue) and the resulting (red) step gradients (left) and linear gradients (right).
