SPE Column for Dioxin Analysis in accordance with JIS

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

How to set-up for normal phase

Detection of dioxins and non-ortho Co-PCB in the toluene fraction (recovery rate: left, amount of the solvent : right)

1. Charge 1 mL of the sample to the upper layer of the Presep Active Carbon-impregnated Silica Gel (Reverse Column). [14 species Co-PCB (each 10 ng/mL), 1,3,6,8-TCDF, OCDD (15 ng/mL hexane solution)]
2. Wash the wall of the glass tube with a small amount of hexane (0.5 mL) and leave it for 10 minutes.
3. Elute with hexane (50 mL) and 25 v/v% dichloromethane/hexane (150 mL). After reversing the column, elute with toluene (100 mL ※10 mL fractions×10)
