About IC

Ion Chromatography (IC) methods were first reported in1850 to analyze calcium, magnesium and ammonium in clay samples!

Today, Ion Chromatography is a highly reliable and widely used technique to analyze environmental, pharmaceutical, and food/beverage samples.

IC methods are typically highly sensitive and do not require extensive sample preparation. However, a common challenge with IC is sample throughput. It can take anywhere from 10 to 20 minutes, and sometimes much longer, to run a single sample.

The Basic Steps Include:

  1. Your sample is injected into the column
  2. Eluent pushes the sample through the instrument
  3. The column separates analytes in sample basic on ionic affinity
  4. Background conductivity is suppressed by chemical or electrolytic suppression
  5. Conductivity is measured and peaks appear at analyte specific retention times

IC is a technique used to accurately separate and quantify ions in complex matrices. Ion exchange chromatography offers extremely high resolving power and high selectivity. The column is packed with a stationary phase designed to separate only negatively or positively charged molecules. A conductivity detector can then measure the changing conductivity of the solution as it elutes from the column. This allows analysts to detect and quantify ionic species with high levels of accuracy and precision.

The key to ensuring these results remain consistent, however, comes down to the use of IC standards. High purity certified reference materials are essential in preserving the accuracy, precision and reliability of measurements obtained through ion-exchange chromatography with conductivity detection.

Never let your eluent run dry!

Using quality, clean eluents is essential for:

  • Analyte retention time
    • Consistency of eluent preparation is key for methods that are validated.
    • Validated methods will reduce time spent running single element standards during troubleshooting.
  • Background conductivity
    • A higher background conductivity will result in loss of sensitivity and higher detection limits.

Are your peaks creeping you out?

Your chromatogram should show healthy peak separation, good sensitivity and results displayed quickly! a healthy chromatogram begins with credible standards.

High purity IC standards are essential for setting up your calibration, confirming your peaks and optimizing your methods. If you are using a CRM that is not pure, you could be seeing contamination appear in your chromatogram.

Master EPA 300.0 and 300.1

These EPA methods are used to separate and quantify anions of interest in environmental samples. A critical aspect of the methods is eliminating measurement uncertainty via a robust calibration process. EPA method 300 states that calibration standards can be prepared from ACS reagent-grade materials, but the only way to ensure quality standards according to an unbroken chain of quality control is by using certified reference materials (CRMs).

Inorganic Ventures uses high purity starting materials for EPA Method 300.0 Rev 2.1 Part A, and 300.1 Part A and B standards, guaranteeing consistency and accuracy in your analysis.

Other Common IC Methods include:

  • ASTM D6919 - Inorganic cation analysis
  • EPA 314.0 - Perchorate in drinking water
  • USP <1065> - IC methods for pharmaceuticals
  • EPA 1621- PFAS by Combustion IC
  • Various methods for NO2/NO3 in food samples
