What is Qualitative Pipetting Monitoring (QPM) and why is it so important?

Translating Pressure Curves into Intelligent Actions

With exceptionally fine resolution, ZEUS X1 monitors the pressure in the air space between the piston and the liquid. By correlating the pressure curve with the movement of the piston, a standard curve for successful aspiration or dispense is established. If deviations from this standard are detected, actionable data is communicated back to the system, which automatically adjusts to ensure that accuracy and precision are not compromised.

What Types of Pipetting Errors are Detected By QPM?

Below are some examples of how the pressure curves for various common pipetting errors will look relative to a successful aspiration.
