The TESSEK Separon polymeric sorbents for gas chromatography are based on macroporous, spherical particles, differing widely in polarity and surface area. Generally they are applicable for separations of low boiling point liquids and gases, the temperature stability is up to 200 °C. No bleeding of stationary phase occurs in the working temperature range.

Six types are supplied as a bulk with particles sizes 100, 150 and 200 µm.

• TESSEK Separon BD
  Co-polymer of butylmethacrylate and divinyl benzene. Nonpolar sorbent with surface area of about 60-120 m²/g.

• TESSEK Separon AE
  Co-polymer of acrylonitrile and ethylene dimethacrylate. Polar sorbent suitable for volatile liquids and gases.

• TESSEK Separon SE
  Co-polymer of styrene and ethyleneglycol dimethacrylate. Medium polar sorbent suitable also for reversed phase liquid chromatography.

• TESSEK Separon AD
  Co-polymer of acrylonitrile and divinylbenzene. Semi polar sorbent with high surface area around 400 m²/g.

• TESSEK Separon CHN
  Co-polymer of acrylonitrile and divinylbenzene especially suitable for analyses of gases and elemental (CHN) analyses. The sorbent has surface area around 650 m²/g.

• TESSEK Separon SDA
  Ternary co-polymer of styrene, divinylbenzene and acrylonitrile, especially suitable for analyses of hydrocarbons and their derivatives. The sorbent has surface area 80-90 m²/g.

The above sorbents are available in 10, 100 g and bulk quantities.
