The packed column injector of a gas chromatograph was modified to accommodate direct injection by syringe onto a wide-bore fused-silica capillary column. No changes were made to the nitrogen--phosphorus detector
Fused silicacapillary or wide bore column (0.32 mm × 30 m (ID) or 0.53 mm × 30 m (ID)) coated with a layer of 1.8 μm or 3 μm of the phase (6 percent polycyanopropylphenyl-94percent dimethylpolysiloxane) which is identical to the columns used in procedure A of the USP. ...
