An internal conventional is critical as a consequence of uncertainties introduced throughout the stable-period extraction. For instance, the quantity of serum transferred into the reliable-section extraction cartridge, 0.5 mL, and the quantity of solvent employed to remove the analyte and interior conventional, 0.25 mL, are incredibly compact. The
