Controlling the pressure
Another crucial parameter to consider when drying water /ACN HPLC fractions using a centrifugal evaporator is pressure control.

Even though mixtures of water/ACN alone may not bump, the addition of actual compounds sometimes changes this. Bumping is preventable by employing a controlled vacuum ramp to the centrifugal evaporator when initially pumping down, and increasing the centrifugal force to greater than 450G....Read more
High performance liquid chromatography (HPLC) is one of the most frequently used analytical separation techniques. A widespread and growing application for HPLC is for product purification following chemical synthesis. Centrifugal evaporation is an ideal technique for drying HPLC fractions as (wi...Read more
