Then
analysis was done by injecting a 1 ll aliquot in a splitless
mode into a Hewlett Packard 6890 gas chromatograph
(Avondale, PA, USA) equipped with a flame-ionization
detector and a DB-5 fused-silica capillary column
(30 m  0:32 mm i.d.; film thickness 1 lm; J&W Scientific,
Folsom, CA, USA). Injector and detector temperatures
were set at 300 C. Oven initiating temperature
was at 190 C, elevated to 215 C at 6 C/min, and
then increased up to 300 C at 32 C/min, held for 3
min. Nitrogen was used as a carrier gas. The percentage
yield (percent weight conversion) was defined as ðmg
biodiesel  mg initial soybean oilÞ  100% and was estimated
using peak area integrated by on-line software
Hewlett-Packard 3365 Series II ChemStation (Avondale,
PA, USA).

lotuslxl(金币+2):能否把条件再说详细点?
用气相色谱DB5的C18柱子程序升温分离就可以了:)
