Notes:

Sulphur

Whilst the scope of ASTM D 5453 is stated to be for various fuels containing 1.0 to 8000 mg/kg total sulphur, IMPCA consider this method to be suitable for the determination of total sulphur in methanol provided that the laboratory performing the analysis has demonstrated that it can achieve a Limit of Detection < 0.5mg/kg with the apparatus available to it.

2. TMA and Aromatics

In case some specific consumers or producers wish to have more specific information on TMA (which can be considered as an impurity generating bad smell) and/or Aromatics (in case the previous cargos have been Aromatics).
