Resolution equations relate the 3 aspects this sort of that top effectiveness and separation aspects Increase the resolution of element peaks in an HPLC separation.
I want to sign up for newsletters from Sartorius (Sartorius AG and its affiliated corporations) primarily based of my own interests.
Ion-exchange: Separates billed analytes based mostly on their own ionic conversation While using the stationary section. Opt for a cation-Trade or anion-exchange column based on your analytes’ demand.
Guard columns: Guard columns are inserted just right before the particular column and capture something That may clog the actual column. Use them!
Depending on their affinity to the stationary and mobile phases, analytes partition amongst The 2 in the separation approach occurring in the column.
