20
Protection column: adsorbing harmful components or particles in the sample or eluent to
protect the chromatographic column.
Separation column: separating sample components.
Self-regenerating suppressor: reducing the background conductivity of eluent; and
improving the signal value of ions to be measured.
④
Constant temperature conductivity cell: detecting separated components.
The specific chromatographic flow path system is described below.
The degassed eluent firstly enters the infusion pump and is conveyed by the infusion pump
into the sample injection valve. When the sample is loaded into the quantitative loop, the sample
injection valve is switched to the analysis state to bring the sample in the quantitative loop into
the flow path. The mixed solution of the eluent and the sample enters the protection column and
chromatographic column in sequence after pre-column preheating in the column heater. After
separation by the chromatographic column, it enters the suppressor and the conductivity cell. The
conductivity cell will analyze the sample. The electrical signal is converted into a digital signal
and transmitted to the computer end for analysis. After the liquid exits the conductivity cell, it
will circulate into the suppressor to replenish the water in the suppressor regeneration chamber.
Finally the waste liquid will enter the waste liquid bottle.
