- Sample(s)
Extract oil-contaminated solids with n-hexane. Homogenise other oil samples and dissolve 1.5 to 2.0 g in 50 mL n-hexane. Water which may cause turbidities can be removed with sodium sulphate.
- Conditions
Determination with reference to German Standard DIN 51 527
Column conditioning: Let 1 mL n-hexane flow through the CHROMABOND SiOH-H2SO4/SA column.
Sample application: Aspirate or force 500 µL sample through the CHROMABOND SiOH-H2SO4/SA column. This phase offers better removal of interfering substances due to sulphonisation. Place CHROMABOND SiOH-H2SO4/SA column on top of CHROMABOND SiOH column with the aid of an adaptor (REF 730100) and after at least 30 s flush sample into the SiOH column with 2 x 1 mL n-hexane.
Elution: Elute SiOH column with 3 x 0.5 mL n-hexane.
Evaporation: Adjust to a suitable concentration for subsequent GC analysis by evaporation of n-hexane in a stream of nitrogen or by dilution with n-hexane.
