A sulfur analysis is essential in petrochemical industries and industrial processes involving compounds of sulfur. Total sulfur analyzer plays the critical role of measuring the content of sulfur in substances such as natural gas, and other compounds.
A total sulfur analyzer is able to detect a wide range of sulfur compounds in different samples without interference from other compounds eliciting similar behavior with sulfur. The central feature of a sulfur analyzer is the oxidization furnace that supports conversion of sulfur compounds present in the sample to Sulfur (IV) Oxide, water and Sulfur (II) Oxide. The spectrophotometer present in some analyzers serves to determine the overall concentration of sulfur (II) oxide. A stack of packed columns located immediately before the entry vents separate the mixture into manageable individual components that are eventually fed into a photometric detector. The photometric detector acts as a measuring chamber for traces of sulfur.
Benefits of using total sulfur analyzer
In any gas analysis, accuracy and precision are of paramount importance. Total sulfur analyzers, therefore, eliminate hazardous effects and fatalities brought about when sulfur gets in wrong places. Besides, the analyzer eliminates the analysis errors that can give rise to the hazards by maintaining the highest degree of accuracy possible compared to other sulfur determination methods. Another thing that makes total sulfur analyzer advantageous is that lead acetate based detection system in some analyzers provide an interference-free output of high accuracy.
Choosing an appropriate total sulfur analyzer
A great total sulfur analyzer should be able to measure utmost five times the indicated range. The analyzer should have the capability to resist unwanted interferences from other compounds that mimic sulfur compounds and ensure the highest degree of accuracy at the same time. The power consumption should be put into consideration as well. An average total sulfur analyzer should use less power and extended running life of at least 60 days if it is using a rechargeable battery. Mains powered total sulfur analyzer need to consume fewer power units. The best analyzers have the output range of between 0-5ppm and 0-100ppm. The calibration checks should be only required every 3 to 6 months.
Sulfur poisoning is a menace in a lot of industrial processes that deal with sulfur compounds to produce other useful substances. This tends to cost companies a lot of money. The total sulfur analyzer has proved to be a really useful tool in mitigating the effects of sulfur poisoning by measuring determining its amount in ingredient compounds.
