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 Phosphorus performance 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, 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 , , , or 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 , , , or in the Maintenance manual. ? Configure the column. 5 If it is not already installed, install the. 6 Create or load a method with the parameter values listed in Table 15.
