IONUS Anion and Cation Analyzer
IONUS anion and cation analyzer can be used for the analysis of anions and cations in research, development and everyday routine
Description
IONUS Anion and Cation Analyzer
IONUS can be used for the analysis of anions and cations in research, development and everyday routine: drinking water and tap water as well as for waters within the scope of environmentally relevant investigations. This chromatograph separates anions (for anions optionally with suppressor technology) according to EPA 300.0 and EPA 300.1 and cations.
Features
IONUS features:
Anion analysis
Applications for F–,Cl–, ClO2-, ClO3-, Br–, BrO3–, NO2–, NO3–, PO43-, SO42-, I– silicate in water with and without chemical suppressor technique (according to EPA 300.0 & EPA 300.1) are available.
Cation analysis
Different methods have been developed for analysis of cations like NH4+, Li+, Na+, K+, Ca2+, Mg2+, Sr2+, Ba2+.
Derivatization
Modified for post-column derivatisation, very low detection levels for bromate (according EPA 317.0 or EPA 326) or transition metals (VIS detection) are realised.
Detection
Anions and cations can be measured subsequently with conductivity detector. If requested the IONUS can be equipped with UV/VIS detector for indirect detection.
Consumables & spare parts
The IONUS is compatible with the common eluents and columns (max. operating pressure 120 bar) for anion and cation exchange chromatography. The customer is not limited to one brand.
Options
manual injection port
anion suppressor technique
based on chemical process regeneration of suppressors with acid.
separation of transition metals
by using carboxylic acids (oxalic, tartaric, citric acid) as eluents and the complexing agent (PAR) 4-(2-Pyridylazo)resorcin the concentration levels of transition metals can be determined.
indirect UV detection
the IONUS can be equipped with an additional UV/VIS detector.
post column derivatization to determine bromate
the bromate analyzer is a dedicated configuration for the analysis of bromate in water based samples with a detection limit of 1 ppb. Depending on what is requested, the derivatization can be performed with Dianisidine (EPA 317) or Triiodide (EPA 326) together with a UV/VIS detector.
