Ion chromatography system for exchanging an ion exchanger in a suppressor and a suppressor means

An ion chromatography system comprising:

• a separating mechanism;
• a suppressor mechanism coupled to the separating mechanism, the suppressor mechanism adapted to receive an eluted liquid from the separating mechanism, the suppressor mechanism having a main body in which an ion exchanger is provided to reduce the electric conductivity of the eluted liquid from the separating mechanism;
• and
• a detector coupled to the suppressor mechanism to detect desired ions in the eluted liquid from the suppressor mechanism,
• wherein the suppressor mechanism includes automatic exchanging means for discharging the ion exchanger from the main body and for supplying a virgin ion exchanger to the main body,
• wherein the main body of the suppressor mechanism is a 6-way switching rotary valve having a first rotary groove a, a second rotary groove b and a third rotary groove c,
• wherein the suppressor mechanism includes a chamber, for accommodating a virgin ion exchanger in a slurry state, coupled to the rotary valve,
• wherein the automatic exchanging means includes (1) a liquid transferring tank, which accommodates a transferring liquid for introducing the virgin ion exchanger in a slurry state in the chamber into the rotary valve, and (2) a liquid transferring means for supplying the transferring liquid,
• wherein a flow passage from the separating mechanism is connected to a flow passage to the detector by the rotary groove a,
• wherein a flow passage from the liquid transferring means to the chamber is connected to a flow passage to the third rotary groove c by the second rotary groove b,
• wherein a flow passage from the second rotary groove b is connected to a flow passage to a discharge passage leading to the outside of the rotary valve by the third rotary groove c, and
• wherein filters, which prevent the passage of ion exchanger are respectively provided at (1) a side of the separating mechanism with respect to the first rotary groove a, (2) a side of the detector with respect to the first rotary groove a, and (3) a side of the third rotary groove c with respect to the second rotary groove b.
