Infusion Pump Ion Chromatography Instruments for Detection of Iodine in Water Quality
Introduction of Ion Chromatography Instrument
Ion chromatography is a form of liquid chromatography used to separate ions in aqueous solutions. Typically, IC analyzes anions such as fluoride, chloride, nitrite, bromide, nitrate, phosphate and sulfate. Ion chromatography can detect other ions as well. Chromate, perchlorate, and organic acids are examples.
Features of Ion Chromatography Instrument
1. Intergrated apperance design, high brightness LCD full touch GUI controller.
2. High degree of automation "One Key Rinse" and "One Key Maintenance" automatic maintenance function.
3. Higher intergration: Support optional parts upgrade to 2D system and multi-detector combination.
4. Full PEEK pump and electric injection valve.
5. Powerful and convenient chromatpgraphy workstation.
6. High precision temperatur-controlled conductivity detector.
