Target group
To what should the user pay particular
attention?
To make your HPLC separations as efficient as possible, pay close
attention to the following:
Avoiding additional
dead volumes
1. Once they have been used, never re-use capillaries in other
areas of the HPLC system.
2. Only use a given PEEK fitting for one specific connection and
never re-use it for others. Always install new PEEK fittings on
each separate port.
Using special
columns
When using special columns, follow the manufacturer's
instructions on caring for the columns!
Checking for clogged
capillaries
Regularly check for clogged capillaries – test back pressure
without column!
Using filtered solvents
1. Use ultra-pure, filtered solvents for HPLC – gradient grade.
2. Filtration of substances under analysis
3. Use of inline filters.
