Reduce pulsation – improve performance and increase longevity of your column using the pulse damper with the AZURA® P 2.1L

When working with preparative liquid chromatography (LC) pumps such as the AZURA P 2.1L some degree of pressure pulsation is to be expected, due to the operating principles of piston pumps. Although the P 2.1L is equipped with active pulsation compensation, residual pulsation cannot be prevented. Residual pulsation is generally not an issue but for certain applications, such as precise dosing or when working with sensitive columns, it can be problematic. Integration of the KNAUER PEEK Pulse Damper into the LC system can mitigate the pump’s pressure pulsation. In the conducted experiments the effect of the pulse damper was most visible with high flow rates up to 100 ml/min.
