Test Standard of TT-IC2800 Ion Chromatograph
ASTM, EPA, SMEWW
Application of TT-IC2800 Ion Chromatograph
It is an analytical instrument used to separate, identify, and quantify ionic species in a sample—typically anions (like chloride, nitrate, sulfate) and cations (like sodium, calcium, ammonium). It is widely used in environmental monitoring, pharmaceuticals, food safety, power plants, and chemical manufacturing.
Features of TT-IC2800 Ion Chromatograph
- The electrochemical suppressor is specifically designed to be continuously self-regenerating.
- Since the eluent has high background conductivity, chemical inhibition must be done so that signals from analytes can be detected.
- The inhibition of background conductivity is achieved through the reaction of CO32- and HCO3- in the eluent with H+ produced by electrolysis to generate H2CO3 of low conductivity during anion analysis and the reaction of H+ in the eluent with OH- produced by electrolysis to generate H2O. H+ or OH- ions are produced by electrolysis without addition of extra eluent to realize automatic regeneration of ion exchange membrane.
- P-200 pump Parallel double plunger reciprocating pump, full PEEK material and pump head, Full control through Ace software or front panel. maximum pressure 35Mpa.
- Conductance detector Fixed frequency bipolar pulse conductance detector with semiconductor thermostatic system to ensure the stability and sensitivity of the detector.
- Anion protection columns Analysis Columns (Anion column for analysis of 8 anions including BrO3-, Cl-, NO2-, Br-, NO3-, HPO42- and SO42-).
- Anion suppressors Self – regenerative electrochemical suppressor, large inhibition capacity, low background conductance, small dead volume, fast balance, easy to maintain.
