sample loops in various sizes. If necessary, the pre-installed 25-
µ
L loop
can be replaced with a loop that has a different sample injection volume.
NOTE The EluGen cartridge requires at least 14 MPa
(2000 psi) of system backpressure for removal of
electrolysis gas from the eluent produced by the
cartridge. A system backpressure of 16 MPa (2300 psi) is
ideal.
If the system backpressure is too low, install a
backpressure coil. Connect one end of the backpressure
coil to Port P (2) on the injection valve; connect the
other end to the
TO INJ VALVE IN - P line. See
Section B.16.1 for details.
