Cover Story: Perchlorate ion is considered an environmental threat due to its ability to disrupt thyroid function. Although it has been found in many environmental samples worldwide, the information on perchlorate contamination of Polish waters is very limited. In the present study, we determined the concentration of perchlorate in various types of water from Poland using ion chromatography with suppressed conductivity detection (IC-CD). Bottled, tap, river and swimming pool water samples were analyzed. Furthermore, we compared the results to the current health advisory level of perchlorate in water. To our knowledge, this is the first attempt to provide information on the perchlorate presence in Polish waters. View this paper

Comparison of the Fitting Performance of Retention Models and Elution Strength Behaviour in Hydrophilic-Interaction and Reversed-Phase Liquid Chromatography

  • Ester Peris-García,
  • María José Ruiz-Angel,
  • Juan José Baeza-Baeza and
  • María Celia García-Alvarez-Coque

Hydrophilic interaction liquid chromatography (HILIC) is able to separate from polar to highly polar solutes, using similar eluents to those in the reversed-phase mode (RPLC) and a polar stationary phase, where water is adsorbed onto its surface. It...
