  2. 1. Packed Column Supercritical Fluid Chromatography : Applications in Environmental Chemistry

    Author : Nicole Riddell; Bert van Bavel; Robert McCrindle; Ingrid Ericson Jogsten; Jake Ryan; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supercritical Fluid Chromatography; Mass Spectrometry; Ionization; POPs; APPI; APCI; chiral; achiral; packed column;

    Abstract : Although gas and liquid chromatography have emerged as dominant separation techniques in environmental analytical chemistry, these methods do not allow for the concurrent analysis of chemically diverse groups of persistent organic pollutants (POPs). There are also a small number of compounds which are not easily amenable to either of these traditional separation techniques. READ MORE

  4. 2. From source to the environment : Strategies for identification and determination of hydroxylated polycyclic aromatic hydrocarbons in complex particulate matrices
