- Empower instrument method
- Gradient Start allows a user to change the time the gradient starts with respect to the injection, adding or decreasing the gradient delay during method transfer.
- Start the gradient "before injection" to move the peaks to earlier retention times.
- Start the gradient "after injection" to delay the gradient shifting peak elution to a later retention time.
When looking at an Empower report, the Gradient Start (Relative to Injection) value will be negative if the gradient starts after the injection
