Allowed pH ranges

Remarks

Vanquish Core

1-13

  • pH value of 2 (Vanquish Horizon/Flex): Short-term use only. The application time should be as short as possible. Flush the system thoroughly after these applications.

  • pH value of 1-2 (Vanquish Core): The application time should be as short as possible. Flush the system thoroughly after these applications.

  • pH values higher than 9.5 with optical detectors: Avoid using mobile phases with a pH value higher than 9.5 together with optical detectors. This can impair the functionality and optical performance of the detector flow cell.

Vanquish Horizon

Vanquish Flex

2-12

Observe the mobile phase guidelines for the detector. See Mobile Phase Guidelines for the Detector.
