Abstract
An analytical system comprises a chromatography column configured to separate a sample into one or more analytes; an ion removal device configured to remove at least ions of one charge from the mobile phase, the ion removal device fluidly coupled to an output of the chromatography column; an ion selective sensor configured to measure a signal corresponding to an activity of the ions of one charge in the mobile phase, the ion selective sensor fluidly coupled to an output of the ion removal device; an optional diverter valve that can interrupt the flow of the mobile phase; and a microprocessor configured to monitor the signal of the ion selective sensor and to either switch the optional diverter valve to interrupt the flow of the mobile phase or turn off the pump when the signal is greater than a predetermined threshold.
