Thermo Fisher Scientific Inc., is pleased to announce the launch of a new Total Sulphur (TS) analyzer, the Thermo Scientific TS 4000. Further expanding on the TS 3000 routine analyzer, the TS 4000 incorporates the patent pending Thermo Scientific True Total Sulphur (TTS) technology, removing nitrogen interference thus providing true total sulphur results. This novel TTS technology is capable of determining trace level sulphur in Cetane Improver, offering high productivity performance allowing for accurate and precise analysis of sulphur levels in automotive fuels. The unique versatility, robustness and sensitivity of the analyzer make it ideally suited for a range of refinery and petroleum sample types with a high nitrogen concentration.
The unique TTS technology has been developed by researchers at Thermo Fisher in response to new regulations including the ASTM D5453 methodology implemented by the United States Environmental Protection Agency (EPA). These regulations dictate strict limitations on the sulphur content levels in automotive fuels. Ultra-low sulphur diesels are already in use across much of Europe and Asia, and are expected to become a viable alternative to mainstream fuels by 2010.
The novel TTS technology defines the amount of nitric oxide (NO) added to the sample in the furnace, inhibiting the formation of SO3, which cannot be detected using UV-F. This results in higher yield combustion of sulphur dioxide (SO2), which can then be detected using UV-F. Featuring the TTS technology, and configured with a UV-F detection system, the Thermo Scientific TS 4000 analyzer is capable of detecting sulphur at extremely low levels in liquids solids and gas samples.
The Thermo Scientific NeXYZ liquid autosampler is supplied as standard with all TS 4000 analyzers. The NeXYZ Autosampler offers quick and easy automatic sample introduction. It is the first universal autosampler that can be used for solids, as well as direct and indirect injection of small volume hydrocarbons.
