What is Dionex ion chromatography?
Ion chromatography is used for water chemistry analysis. Ion chromatographs are able to measure concentrations of major anions, such as fluoride, chloride, nitrate, nitrite, and sulfate, as well as major cations such as lithium, sodium, ammonium, potassium, calcium, and magnesium in the parts-per-billion (ppb) range.
What is the principle of ion chromatography?
Ion Chromatography is a method for separating ions based upon their interactions with resin (stationary phase) and the eluent (mobile phase). These phases differ between an anion column, which attracts anions, and a cation column, which attracts cations.
How do Eluents work?
A sample of the mixture to be analyzed (analyte) is injected into a carrier fluid (the eluent) the combination is passed through a column containing a stationary fixed material (adsorbent) Compounds contained in the analyte are then partitioned between the stationary adsorbent and the moving eluent/analyte mixture.
What is the mechanism of ion exchange chromatography?
Ion-exchange chromatography uses column packing material that has charge-bearing functional groups attached to a polymer matrix. The mechanism in this type of chromatography is the exchange of sample ions and mobile-phase ions with the charged group of the stationary phase.
What is an IC instrument?
Ion chromatography (IC) systems separate charged particles from a liquid and measure their concentration. IC systems can analyze particles such as anions, cations, organic salts, and proteins. They are used in environmental, manufacturing, food, pharmaceutical, and chemical industries.
What does thin layer chromatography tell you?
Thin layer chromatography, or TLC, is a method for analyzing mixtures by separating the compounds in the mixture. TLC can be used to help determine the number of components in a mixture, the identity of compounds, and the purity of a compound.
Is eluent and solvent the same?
As nouns the difference between solvent and eluent is that solvent is a liquid that dissolves a solid, liquid, or gaseous solute, resulting in a solution while eluent is (analytical chemistry) in chromatography, a solvent used in order to effect separation by elution.
What type of chromatography is ion exchange?
The two types of ion chromatography are anion-exchange and cation-exchange. Cation-exchange chromatography is used when the molecule of interest is positively charged. The molecule is positively charged because the pH for chromatography is less than the pI (a/k/a pH(I))….Ion chromatography.

What is suppressor column?
A Suppressor is a device placed between the column and the detector, and acts to reduce the background conductivity of the eluent and enhance the conductivity of the analytes. For anion analysis, the suppressor is a high capacity cation exchange membrane or resin in the acid form.
What is the difference between IC and ICP?
The only difference between the ICP and IC products of each listed analyte is how the impurities are reported; the ICP product includes information on trace metals impurities while the IC product is supplied with a chromatogram.
