Derivatization with NBD-Chloride . (7-Chloro-4-Nitro-2,1,3-Benzoxadiazole) Collection: Sep-PAK Florisil coated with NBD-Cl (Tubes . used in OME 40 NBD-CL on XAD-7 may work) Air Vol and FLowrate: 100L at 0.8-1.2L/min Analysis: 2 mL of MeOH were used to dynamically desorb . the derivative. The samples stood at room temp . for 15 minutes before analysis by HPLC. Column: Develosil ODS-3 10cmx4mm at 30 deg C Eluent: 45/55 acetonitrile/water at 1 mL/min. Detector: UV at 425nm or fluorescent at 425 nm excitation . and 510 nm emission. Mercaptans studied: Methyl, ethyl, isopropyl, propyl, . 2-methyl-2-propyl, 2-butyl, . 2-methyl-1-propyl, and 1-butyl
