Anglo-Norwegian oil programme - intercalibration of analytical methods
Original version
This report is not to be quoted without prior consultation with the General Secretary.Abstract
An attempt has been made to intercalibrate the analysis of three groups
of aromatic compounds present in a sample of Ekofisk crude oil using gas
chromatography - mass spectography. The results are not as good as was hoped.
Two possible sources of error have been identified, one instrumental and the
other related to the assumptions which had to be made regarding the responses
given by different compounds of the same group but of different molecular weights
or isomers of the same group. Proposals are made for overcoming these
difficulties. Wider participation is invited in a repeat exercise and in a
similar exercise involving the simpler u/v fluorescence method of analysis.
