Chlorine Determination in Petro Matrices

Offshore-produced oil contains considerable chlorine contents, which adversely affect the transportation and refining process. High temperature oxidation followed by coloumetric titration is the ideal technique to determine this parameter but suffers from incomplete combustion, escalating with the sample complexity. But the intelligent flame sensor technology of multi EA 5000 from Analytik Jena (Germany) fully automatically takes the varied combustion behaviours of samples and different quantities into account, which leads to complete oxidation, small variations, less need for replicates, and a distinct reduction of maintenance requirements. Besides, it is twice as fast as common systems, allows to calibrate the system independently of the sample matrix, and ensures automated analysis even of unknown samples.
