A 30 m long HP Plot Q column
(0.32 mm i.d., 0.2 mm
film thickness) for TCD, and a 30 m long HP-
Wax Bonded polyethylene glycol capillary column (nominal
diameter 250 mm, 0.25 mm
film thickness) for FID. The detector
temperature was kept at T = 473.15 K, while injection part
temperature was held at T = 423.15 K. Injections were performed
on the split 1/100 mode. Nitrogen was used as a carrier at a rate of
0.1 cm3 min1.
