Wayeal Ion Chromatography Instrument for Environmental Water Quality Analysis
Introduction of Ion Chromatography Instrument
Ion chromatography instrument is a type of high performance liquid chromatograph, so it is also known as high performance ion chromatography (HPIC) or modern ion chromatography, which differs from traditional ion exchange column chromatography mainly because the resin has a high cross-linkage and low exchange capacity, and the injection volume is very small.
Features of Ion Chromatography Instrument
1. The integrated design and compact layout minimise the connections between the components, reducing the dead volume of the system and ensuring superior chromatographic performance.
2. 10.0" high brightness LCD touch GUI controller, synchronised with the chromatography workstation, allows full operation of the instrument and spectrogram display etc.
3. acid and alkali resistant materials such as PEEK, PTFE, PP and other plastics are used for the drenching liquid storage, liquid circuit piping and joints.
4. Full plastic colour identification of high and low voltage pipelines for easy identification of the customer's operation and improved self-protection of the system
5. Built-in column temperature chamber to shorten piping connections and reduce dead volume and peak spread within the system.
6. Precision temperature-controlled conductivity detector, user can set the temperature according to their actual working environment.
