Test methods for sulphur < 10 ppmw in fuels

[gegio1960]

Dear all,
do you have practical experiences in the application of test methods for the analysis of Total Sulphur in diesel / kerosene / gasoline products when the concentration is under 10 ppm by weight?

The following list includes ASTM methods theoretically applicable in this very low range of concentration:
- D 4045
- D 1266
- D 3120 (only for gasoline / kero)

Moreover, ASTM D 2622 should be applicable above 10 ppmw, but my last reference on it is dated 1992. Maybe in the meantime this limit has been relaxed?

Thanks for any help you can give!

Bye,
gegio

You are right, there is a new D 2622-98 with references to lower than 10 ppm and the measurements st. dev.
