3.12 Conductivity monitor
Function of the Conductivity
monitor
The Conductivity monitor continuously measures the conductivity of buffers and eluted
proteins.
The Conductivity flow cell has two electrodes positioned in the flow path of the cell. An
alternating voltage is applied between the electrodes and the resulting current is mea-
sured and used to calculate the conductivity of the eluent.
The conductivity is automatically calculated by multiplying the measured conductance
by the cell constant of the flow cell. The cell constant is factory-calibrated on delivery
but can be re-calibrated if needed, see Section 7.7.3 Calibrate the Conductivity Monitor,
on page 327.
As variation in temperature influences conductivity readings, the conductivity flow cell
is fitted with a temperature sensor that measures the temperature of the eluent. A
temperature compensation factor can be set in System settings and is used to report
the conductivity in relation to a set reference temperature.
