Adding the dynamic mixer to the Accela™ Pump ensures mixing of complex or relatively incompatible solvents and 
reduces the chromatographic baseline noise for applications using proportioned mobile phases. The mixer also 
increases the accuracy and reproducibility of complex ternary and quaternary gradients. The mixer adds 35 μl of 
gradient delay volume to the system.
