To Verify FPD Performance (Sample 5188-5245, Japan) Page 1 of 6 Chromatographic Checkout : To Verify FPD Performance (Sample 5188-5245, Japan) To Verify FPD Performance (Sample 5188-5245, Japan) 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, Japan), composition: n-Dodecane 7499 mg/L (± 5%), Dodecanethiol 2.0 mg/L (± 5%), Tributyl Phosphate 2.0 mg/L (± 5%), tert-Butyldisulfide 1.0 mg/L (± 5%), in isooctane as solvent 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. Inlet and injector hardware (See “To Prepare for Chromatographic Checkout.”) 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 Replace consumable parts (liner, septum, traps, syringe, and so forth) as needed for the checkout. See “To Prepare for Chromatographic Checkout.” 4 Verify the lit offset is set appropriately. Typically,
