Product catalog summary
Overview: Galvanic Applied Sciences Inc. offers a series of sulfur chemiluminescence analyzers designed for precise sulfur measurement in various hydrocarbon samples. The 840 series includes four models tailored for different applications in laboratories and process environments.
Sulfur Chemiluminescence Applications: These analyzers are used for detecting sulfur in refined petroleum products, LPG, LNG, natural gas, refinery fuel gas, gasoline, diesel, and more. They measure total sulfur in liquids and sulfur components in vapor samples using gas chromatography.
Principle of Operation: The analyzers operate on a two-stage detection method where sulfur monoxide is generated and reacts with ozone to produce sulfur dioxide and light. This light is measured to determine sulfur content. The process involves a reaction furnace, chemiluminescent detector, and ozone generator.
Advantages: The analyzers offer equimolar response to all sulfurs, linearity from ppb to percent concentrations, sulfur specificity with no known interferences, and low hydrogen consumption. They are simple to calibrate and do not require a flame or nuclear source.
Model Specifications:
  • Model 840: Designed for lab use, measures total sulfur in gases or liquids, controlled by Peak Simple® software, and offers flexible analysis without requiring a column.
  • Model 843: A lab analyzer for sulfur components in vapor samples, uses capillary columns for separation, and is controlled by Peak Simple® software.
  • Model 841: For continuous total sulfur measurement in gases or liquids in process environments, does not require columns, and uses a proven chromatograph valve.
  • Model 842: An online analyzer for unattended sulfur component measurement in vapor samples, uses reliable chromatograph valves and capillary columns.
Calibration and Configuration: The analyzers use a single least reactive sulfur component for calibration, simplifying the process. Models 841 and 842 include Windows-based configuration software for system setup and monitoring.
Technical Specifications: The analyzers offer a detection range from 0-1 ppm to 0-1%, with 10 ppb detectability for gases and 100 ppb for liquids. They feature a general-purpose electrical classification, optional configurations, and various output options.

Due to the reactive nature of sulfur compounds, calibration standards containing multiple sulfur components are normallyunstable. This is particularly true at the lower ppm levels. The equal and selective response to sulfurs from the Sulfur Chemiluminescence DetectorӔ allows the standard to be made up with a single least reactive sulfur component in an inert background gas such as nitrogen. This standard is then available for on-line auto calibration and reference check functions eliminating most of the expensive technician time required for other calibration methods commonly used only in the...

The Galvanic AppliedSciences model 840is a lab analyzerdesigned to measuretotal sulfur in gases orliquids. Samples areinjected into a heatedvaporization blockthrough a septum,either manually or withan auto injector. The840 is highly flexible,allowing analysis ofliquids or gases over alarge range of sulfur concentrations. The operation of the 840 is controlled by Peak Simple > Ү software running on a PC or laptop. Extensive reporting options areavailable, and automated operation is possible with the optional auto injector. No column is required, and analysis times range from three minutes for...
