Designed according to JIS K 0311 (Method for determination of dioxins and coplanar PCB in exhaust gas) and JIS K 0312 (Method for determination of dioxins and coplanar PCB in industrial water and waste water)

  • Column plug and moisture-proof aluminum packaging bag prevent quality deterioration during storage.
  • Ideal for analysis of dioxins* (Blank test for dioxins and coplanar PCB by high-resolution GC/MS has been implemented.)
  • Fraction test for dioxins and coplanar PCB has been carried out (Presep® Alumina, Activated DX).
  • Less eluent needed by applying reflux extraction (Presep® Active Carbon-impregnated Silica Gel Reverse Column)

    *Except Presep® Multi-layer Silica Gel

Dioxin Analysis Flow


Multi-layer Silica Gel


Overview / Applications

Outline The product is a column tube filled with silica gel such as 10 % silver nitrate-silica gel or 22 % sulfuric acid silica gel to be used for the analysis of dioxins according to formula specified in JIS.As a part of pretreatment for the analysis of dioxins, cleanup should be carried out with a multilayer silica gel column with various kinds of chemically-modified silica gel laminated in it. This should be done in order to efficiently remove contaminants such as sulfer containing compounds, polycyclic aromatic hydrocarbons, and colored components present in measurement samples. However, filling procedures to prepare the multilayer silica gel columun are extremely complicated.
