The high-pressure ion chromatography system, consisting of an ICS-5000+high-pressure ion chromatography instrument integrated with a capillary system and analysis system, can meet potential challenges and advanced applications in the future. This system improves work efficiency, expands work capabilities, and enhances chromatographic performance.

This product has a pressure resistance of up to 6000psi, and the use of a high-pressure pump means it can be compatible with small-sized chromatography columns, which are the core of the chromatograph. The smaller the particle size, the less resolution loss and higher sensitivity at higher flow rates. Another feature is the detector. The commonly used detector for ion chromatography is the conductivity detector. This instrument uses an amperometric detector and a conductivity detector, with dual detectors * compatible.

What are the maintenance techniques for high-pressure ion chromatography systems in daily life?

1： Maintenance of High Pressure Constant Flow Pump

1. Work pressure should be appropriate

The working pressure of the pump should not exceed the specified maximum pressure, otherwise it will cause deformation of the high-pressure sealing ring and result in leakage. When using the "flow selection" switch, avoid turning it from 0 to 9, which may cause the column pressure to rise and damage the column and high-pressure constant flow pump.

2. Prevent damage caused by empty pump operation

When the pump is working, the solution should be observed at all times, and attention should be paid to prevent the mobile phase in the bottle from being used up. It is strictly prohibited to absorb the solution dry. Otherwise, the operation of the empty pump will wear down the plunger, sealing ring, or cylinder body, ultimately resulting in leakage. The filter head should always be immersed at the bottom of the solution to avoid inhaling bubbles upwards instead. Turn off the machine when replacing the liquid.

3. Preventing damage to high-pressure constant current pumps caused by solid particles

Any solid particles entering the pump body, including dust or any other impurities, will wear down the plunger, sealing ring, cylinder body, and one-way valve. Filters such as filter membranes (012 ∧ m or 0145 ∧ m) can be used to remove any solid particles from the mobile phase. The filter should be replaced frequently, and the sand core filter head at the inlet should be cleaned regularly.

2： Maintenance of the sampler

1. Cleaning of the sampler

After each analysis, rinse the injection port repeatedly to prevent cross contamination of the sample.

2. The injection speed should be appropriate

For manual injectors, attention should be paid to the quick movement of the valve during injection to avoid overpressure, leakage of the flow pipeline, or pump shutdown; But it should not be too strong to avoid damaging the six way valve.

Alright, that's the introduction to the high-pressure ion chromatography system.
