    Ion Chromatography (IC) is a type of high performance liquid chromatography (HPLC), which is a liquid chromatography method for analyzing anions and cations.

    Ion chromatography can help you identify and quantify organic and inorganic ions, ranging from the traditional pharmaceutical industry to the cosmetics industry. T,C&A Lab's analysis services based on ion chromatography provide you with a state-of-the-art IC platform to meet your needs for the analysis of anions, cations, and organic compounds.

    Ion Chromatography (IC)

    Detection principle

    Most ionized substances will ionize and produce conductance in solution. Through the detection of conductance, the ionization degree of most ionized substances can be analyzed. Since most ionized substances are completely ionized in dilute solution, the content of the tested substance can be detected by measuring the conductivity value. Therefore, the universal detector of ion chromatography is mainly based on conductance detector.

    Detection capabilities

    • Anion analysis
    • The first and preferred method (the most basic application).

    • Cation analysis
    • Simultaneous determination of alkali metals, alkaline earth metals, organic amines and ammonium elements, analysis of transition metals, rare earth elements and valence states.

    • Organic compounds
    • Water-soluble and polar compounds, organic acids, organic amines, sugars, amino acids, antibiotics.


    • Fast and convenient
    • The average analysis time of 7 common anions (F-, Cl-, Br-, NO2-, NO3-, SO42-, PO43-) and 6 common cations (Li+, Na+, NH4+, K+, Mg2+, Ca2+) is less than that of 8min, respectively. It takes only 3min to reach the baseline separation of the above seven most important common anions with a high efficiency and rapid separation column.

    • High sensitivity
    • The concentration range of ion chromatography analysis is as low as μg/L (1-10 μg/L) to hundreds of mg/L.

    • Good selectivity
    • The selectivity of the IC method for the analysis of inorganic and organic anions and cations can be achieved by selecting appropriate separation methods, separation columns and monitoring methods. Compared with HPLC, the relative selectivity of immobilization in IC has a greater impact.

    • Simultaneous analysis of multiple ionic compounds
    • Compared with photometric method and atomic absorption method, the main advantage of IC is that it can detect multiple components in the sample at the same time. It only takes a short time to get all the information of anions, cations and sample composition.

    • The separation column has good stability and high capacity
    • Different from the silica gel packing used in HPLC, the high pH stability of the IC column packing allows the use of strong acids or strong bases as eluents, which is beneficial to expand the application range.

    In conclusion, T,C&A Lab can offer IC services that can solve materials testing related problem. Finally, please complete the form to have an expert discuss your needs.
