Rtx®-Mineral Oil Columns
(fused silica)
• Application specific columns meet DIN EN ISO 9377-2:2000 requirements.
• Optimized column dimensions for fast mineral oil screening.
• Surface linked phase guarantees long lifetime, robustness, and stability to 400 °C.
The Rtx®-Mineral Oil stationary phase and column dimensions were optimized for the
fast screening of mineral oils in extracts from solids and water samples according to
DIN EN ISO 9377-2:2000. The 0.10 µm column is the gold standard for the method,
whereas the 0.15 µm column provides more complete separation of C10 from the sol-
vent peak when large injection volumes are used. Compared with common industry
solutions, the unique surface bonding of the Rtx®-Mineral Oil column ensures long
column lifetime, even at higher temperatures. These unique columns can be used at
temperatures ranging from 380 °C (isothermal) to 400 °C (programmable), and each
column is tested individually for bleed to ensure exceptional performance at these ex-
treme conditions.
