Application note documents on-line analysis of ultra-low concentrations of sulphur in diesel fuel by the pyro-electrochemical method
Spectro Analytical Instruments has released a new application note that documents a simple, cost-effective method of analysing diesel fuel to determine the presence of ultra-low concentrations of sulphur.
The note summarises the results of long-term tests conducted using the company's model 682P-EC pyro-electrochemical on-line sulphur analyser.
In addition to quick response time and excellent precision, the results showed negligible drift when the analyser was operated unattended for periods of up to 26 straight days.
Precision and stability of operation are of significance importance when determining the presence of sulphur during the fuel production process.
By providing an accurate, stable analysis of sulphur content, the model 682P-EC gives operations personnel a reliable means of ensuring that the diesel fuel produced contains the appropriate amount of sulphur as required by governmental emission regulations.
The model 682P-EC was selected to perform the tests because of its exceptional sensitivity and long-term stability. The pyro-electrochemical method conforms to ASTM standard D 6428 and is the EPA designated test method for ultra low levels of sulphur in diesel fuels.
