Then the fiber was transferred to a 4 mL vial which was filled with 100 μL of trifluoroacetic anhydride and stood 30 sec for headspace extraction. Afterward the fiber was transferred again to another blank 4 mL vial and stood 10 min for on-fiber derivatization before the analysis with GC/MS. The absorption-time profiles for both furoic acid and creatinine were examined.
