Title: Liquid Chromatographic Determination of Low
. Molecular Weight Alkylthiols in Air via
. 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)

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
