Carbonate eluent4
Analytical columns using hydroxide eluent or carbonate eluent can be used for oxyhalide analysis. (thermofisher.com)
Determination of inorganic anions has been traditionally performed using carbonate eluent columns. (thermofisher.com)
Hydroxide-selective columns, despite providing better sensitivity than carbonate eluent columns, were not widely adapted due to the lack of appropriate column selectivity and easy contamination during the preparation process for hydroxide eluent. (thermofisher.com)
Traditionally, carbonate eluent is used for anion separations because carbonate eluent is easy to prepare without contamination concerns and delivers results that meet the analytical requirement for regulatory standards of inorganic DBPs as in EPA Method 300.1 (Part B). However, the detection sensitivity using carbonate eluent columns is much lower compared to hydroxide eluent columns as described above due to the higher background and therefore lower signal-to-noise ratio.

Column4
Despite good solubility in the mobile phase and even though the chromatograms obtained show good repeatability, it is possible that this method cannot be used with certain polymer types because of specific interactions (e.g. adsorption) within the sample/eluent/column system (see also Clause 12).
