Total Sulfur in Butane by Excimer UV Fluorescence

Accurate low-level measurement of Total Sulfur in natural gas and related LNG products is becoming increasingly important. The ATOM SGA-1000 online process analyzer incorporates patented Excimer UV Fluorescence (EUVF) technology and is ideally suited for measurement of Total Sulfur in a variety of applications, including low-level sulfur analysis in hydrocarbon products and process streams.

An application where the SGA-1000 has demonstrated exceptional analytical performance is the measurement of total sulfur in butane in the range of 0-10 ppm/vol. Acquired test results reflect excellent linearity, precision and long-term stability. Analytical results represented were obtained utilizing standard bottled air for combustion, consuming a mere 120cc/min. enabling a typical 300 ft3 bottle to last about 6-weeks.

The SGA-1000 is designed for high-speed, high sensitivity analysis with fast response time. Typical analysis time is only 100 seconds, although cycle times of 60 seconds or less are achievable with a moderate increase in utility gas consumption. Instrument operation is simplified with intuitive and user-friendly software, with an added feature that allows data averaging for enhanced analytical precision.
