Thermo Fisher Scientific Inc. announces the launch of a new Total Sulfur (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 Sulfur (TTS) technology, removing nitrogen interference thus providing true total sulfur results. This novel TTS technology is capable of determining trace level sulfur in Cetane Improver, offering high productivity performance allowing for accurate and precise analysis of sulfur 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.
