What is the "Gradient Start" setting in an Empower instrument method? - WKB2231

Article number: 2231

ENVIRONMENT

  • Empower instrument method

ANSWER

  • 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.

ADDITIONAL INFORMATION

When looking at an Empower report, the Gradient Start (Relative to Injection) value will be negative if the gradient starts after the injection
