Optimization of headspace single-drop microextraction technique for extraction of light hydrocarbons (C6–C12) and its potential applications

Formation and evolution of solid bitumen during oil cracking

“…The C 6 ÀC 12 hydrocarbons in the pyrolysates were ultrasonically extracted into the methanol before being analyzed using a headspace single-drop microextraction technique coupled with GC flame ionization detection (Fang et al, 2011).…”

Variation in abundance and distribution of diamondoids during oil cracking

“…C 2 -C 5 gaseous hydrocarbons include C 2 , C 3 , i-C 4 , n-C 4 , i-C 5 , and n-C 5 alkanes, and C 6 -C 12 gasoline hydrocarbons refer to C 6 -C 12 n-alkanes. microextraction coupled with GC-flame ionization detection (Fang et al, 2011).…”

The origin and evolution of thermogenic gases in organic-rich marine shales

“…Process of the indigenous generation of thermogenic gas in shale (modified from Jarvie et al, 2007). hydrocarbon compositions were then analyzed using headspace single-drop microextraction coupled with GC flame ionization detection (Fang et al, 2011). Briefly, fifty microliters of the sample was spiked into a 10 mL glass vial with 5 mL of water, and a magnetic stir bar, and an aluminum cap seal containing a PTFEfaced silicone septum.…”
