Dear Eudes,

1. Look for method in document NX 8250000 of the Registry of Toxic Effects
of Chemical Substances (RTECS) of the National Institute of Occupational
Safety and Health of the USA. Possibly the library of the USA Embassy has a
copy. You can also find some useful info in the safety data sheet of the
compound (probably in the Internet).

2. A chromatographic method, either HPLC or GLC is probably what you need.
It is possible that an instrument manufacturer has published a leaflet on
BITC or similar compounds. Try the commercial agents of such instruments.

3. Other methods are also possible. A review including more than 60
references on the analysis of isocyanates and isothiocyanates appeared. I'm
sure you'll find there the sample preparation and end analysis methods you
need:

J. Zabicky,"Analytical aspects of alkynes, nitriles, cyanates,thiocyanates
and their isomeric functional groups", in "The Chemistry of Triple-Bonded
Functional Groups. Supplement C2", S. Patai (ed.), John Wiley, Chichester,
1994. pp 191-230. The part that interests you is on pages 221-226, 229-230.

All the best
