Measure Trace Sulfur in Natural Gas and LNG SEAMLESSLY

The Trace S-1000™ Uses Excimer UV Fluorescence Technology

Driven by an increasing need for total sulfur trace analysis in natural gas and LNG products, ATOM Instrument developed the Trace S-1000. This remarkable online process analyzer incorporates patented Excimer UV Fluorescence (EUVF) Technology and is specifically designed for measurement of trace total sulfur content in applications that require the ultimate in low-level sensitivity, such as polymer-related applications.

One application where the Trace S-1000 has demonstrated exceptional analytical performance is the measurement of total sulfur in butane at the ultra-low range of 0-1000 ppb/vol. Acquired test results reflect excellent linearity, precision and long-term stability for this extremely low range. Analytical results represented were obtained utilizing an oxygen/argon blend for combustion. The Trace S-1000 provides unparalleled sensitivity and rapid response to concentration changes with a typical analysis time of only 180 seconds.

DELIVERING Advanced Sulfur Analysis FOR NATURAL GAS & LNG

Instrument operation is simple with an intuitive and user-friendly software, with an added feature that allows data averaging for enhanced analytical precision.
Eight-hour repeatability using a sulfur dioxide (SO2) permeation tube for sulfur addition to instrument-grade butane demonstrated a SD of 14.7 ppb at 205 ppb/vol. concentration or 7.17% RSD.
Using the moving average feature, a 3-run analysis (9-min. response time) further improved repeatability, yielding a SD of 8.5 ppb or 4.16%.
Various concentrations run for linearity characterization reflect rapid response, outstanding repeatability and excellent linearity with a 0.9965 correlation.

Excimer UV Fluorescence (EUVF) Provides Low Range Detection and Stability

The Trace S-1000 with EUVF is a field proven technology that utilizes an excitation wavelength that achieves high detection sensitivity and detector stability. The Trace S-1000 is an excellent fit for applications in the 0 – 1 ppm range and is exceptionally stable, even at concentrations less than 1 ppm. The Trace S-1000 is designed for outdoor installation and use in harsh environments as may be required by the refining (LPG), Gas Processing (NGL) and Natural Gas industries.

Simplified Design Improves Certification and Process Monitoring

The model Trace S-1000 total sulfur measurement provides complete analysis of all sulfur compounds potentially present in process gas streams and not just a few selected sulfur compounds as with some GC/TDL applications. Calibration and Validation is seamlessly incorporated with an optional calibration switching configuration and associated software for easy compliance or verification testing.
