Your IC results are only as good as your sample vials
Summary
Polymeric sample vials are frequently contaminated with leachable organic or inorganic ions, which originate from the production process or the raw material. These substances can falsify measurement results. The study at hand compares the leaching properties of several vial types from different manufacturers, showing considerable variations in quality and proving the importance of the right choice of vials for ion chromatography (IC). This white paper also provides recommendations and precautions to further reduce leachable contaminants for IC trace analysis.
