DM-TCEP

• 1,2,3-Tris[2-cyanoethoxy]propane

• Highly polar phase

• General purpose column, ideal for aromatics and oxygenates in gasoline

• Temperature range: 0 ºC to 135 ºC

• Similar to CP-TCEP

Most gasolines contain aliphatic hydrocarbons up to C12. To separate aromatics and oxygenates in gasoline effectively, it is desirable to elute benzene after C11 and toluene after C12. The strong polar DM-TCEP stationary phase offers a retention index for benzene greater than 1,100 ppm and can separate alcohols and aromatics from the aliphatic constituents in gasoline.

DM-TCEP column has the same high polarity as packed columns, which is a column used for analysis of petroleum oxygenates listed in ASTM D4815 with higher efficiency.
