To Verify FPD Performance (Sample 5188-5245) 页码，1/5 Chromatographic Checkout : To Verify FPD Performance (Sample 5188-5245) To Verify FPD Performance (Sample 5188-5245) To verify FPD performance, first check the phosphorus performance, then the sulfur performance. Preparation 1 Gather the following: • Evaluation column, DB5 15 m 0.32 mm 1.0 µm (123-5513) × × • FPD performance evaluation (checkout) sample (5188-5245) • Phosphorus filter • Sulfur filter and filter spacer • 4-mL solvent and waste bottles or equivalent for autoinjector. • 2-mL sample vials or equivalent for sample. • Chromatographic-grade isooctane for syringe wash solvent. 2 Verify the following: • Capillary column adapter installed. If not, install it. • Chromatographic-grade gases plumbed and configured: helium as carrier gas, nitrogen, hydrogen, and air. • Empty waste vials loaded in sample turret. • 4-mL vial with diffusion cap filled with isooctane and inserted in Solvent A injector position. 3 Verify the lit offset is set appropriately. Typically, it should be about 2.0 pA for the checkout method. 4 Install the evaluation column. (See the procedure for the SS, PP, COC, or PTV in the Maintenance manual.) • Set the oven, inlet, and detector to 250 °C and bake out for at least 15 minutes. (See the procedure for the SS, PP, COC, or PTV in the Maintenance manual.) • Configure the column. Phosphorus performance 5 If it is not alr
