Solvent Compressibility Calibration
Solvent compressibility is a function of solvent type and pressure. In order to
optimize flow accuracy and pressure ripple, the compressibility of the solvent
must be considered. The binary pump firmware contains compressibility
parameters for most commonly used solvents. A compressibility calibration
function is available to generate compressibility data for unlisted solvents (see
"Binary Pump Solvent Compressibility Calibration"
compressibility data are stored in an XML file and can be transferred to other
InfinityLab LC Series binary pumps.
Pump Elasticity Calibration
Various parts in the flow path of the binary pump have a certain elasticity
which needs to be compensated to obtain the lowest pressure-, flow- and
composition ripple possible. This is done by running an elasticity calibration
after maintenance and major repairs. For details see
Calibration"
Pump Leak Rate Test
The Pump Leak Rate Test is a diagnostic test designed to determine the pressure
tightness of the pump components. When a problem with the pump is
suspected, use this test to help troubleshoot the pump and its pumping
performance, see
