Ion chromatograph is a kind of high performance liquid chromatography, so it is also called high performance ion chromatography (HPIC) or modern ion chromatography. Ion chromatograph is mainly used for the detection and analysis of common anions and cations in the fields of environment, food, biology, medicine, and chemical industry.

Things to know before using laboratory ion chromatograph:

1. The filter head in the mobile phase bottle should always be below the liquid level to prevent the solution from being sucked dry.

2. Before starting the pump, check whether there are air bubbles in the pipeline between the mobile phase bottle and the pump, and remove them if any.

3. When cleaning the entire flow path with deionized water or mobile phase, please use high-flow cleaning to shorten the cleaning time, but when connecting the mobile phase to the chromatographic column, remember to adjust the flow to the flow conditions of the chromatographic column.

4. Use an optical ion chromatograph for detection, pay attention to turn on the current knob when passing through the mobile phase, and turn off the current before turning off the high-pressure pump after the experiment is completed.

5. When the ion chromatograph is injecting samples, the valve should be moved carefully, not too fast, so as not to damage the valve body, nor too slow, so as not to cause sample loss. During the sample injection process, it is necessary to strictly follow the cleaning procedure to reduce the impact of the previous sample residue on this test.
