Add 0.1 mL of 10 mM labeling reagent 1 / acetonitrile solution, 0.25 mL of 2 µM carboxylic acid / acetonitrile solution, and 0.15 mL of 10 mM 2,2’-dipyridyl disulfide-triphenylphosphine / acetonitrile solution to a vessel, and react the mixture at room temperature for 4 h. Use the resultant as an HPLC sample solution.
For example, the detection limit (S/N=2) for naproxen is 10 fmol.
