Details of Ion Chromatography (IC)

ANALYTICAL INFORMATION:

Material identification - Reference materials are needed

Quantification - Concentrations of components can be determined by establishing a standard curve of known concentrations.

Sensitivity - detection limits down to part per billion levels.

SAMPLE REQUIREMENTS:

Sample must be able to go into solution with a solvent compatible to the IC system, or the components of interest must be able to be extracted from the sample.

Components of interest must cause a change in the conductivity of the solute to be detected.

SUPPLEMENTAL INFORMATION:

Typical analysis time - 1 hour for setup and analysis of one sample, 15-30 minutes for each additional sample

Sensitivity achieved is dependent on sample size and matrix

Unique Capabilities:
· Ion Chromatography allows the separation and detection of:
- trace ionic species such as F-, Br-, Cl-, NO2-, NO3-, HPO4-2, SO4-2, Li+, Na+, K+, Mg+2, Ca+2, Sr+2, Ba+2
- ammonium and low molecular weight amines
- quaternary ammonium compounds
- oxyhalides
- weak organic acids
- silicates
- aliphatic and aromatic sulfonic acids
- carbohydrates
- amino acids
