SKU325270


OI Analytical’s S-PRO 3200 is a complete turn-key system for sulfur analysis in gas-phase samples. Designed to work with our new, patented 5383 Pulsed Flame Photometric Detector (PFPD), the S-PRO 3200 is a powerful analytical tool capable of obtaining simultaneous sulfur and hydrocarbon chromatograms from a single detector.

  • Overview

    The S-PRO 3200 is a custom-configured gas chromatograph for selective, high-sensitivity measurement of sulfur compounds in gas-phase samples and Liquified Petroleum Gas (LPG) streams (such as propylene and ethylene).

    The key technology within the S-PRO is the 5383 PFPD, which has a linear equimolar response to sulfur allowing selective measurement of individual sulfur species from low ppb to ppm levels, and total sulfur as the sum of individual peaks.

    We have integrated a number of special design features into the System’s GC platform, the Agilent 7890 GC System, to provide unique analytical and performance capabilities. Platform features include:

    • Permeation Oven
      • Accommodates up to 5 permeation devices
      • Pure sulfur compound diffuses across a permeable Teflon® barrier at a temperature-dependent rate
      • Precise oven temperature control produces a constant diffusion rate
      • Controlled, measured flow of dilution gas creates an accurate gas standard for calibration
      • Agilent 7890B keypad- or ChemStation-controlled temperature and dilution gas flow
    • Automated Injection System
      • 4-port sample selection valve enables sample selection from a gas stream, or to deliver calibration and check standards from the permeation oven
      • 6-port gas-phase switching valve with sample loop injects samples through the Volatiles Interface into the GC column
    • Sulfur Detection – PFPD
      • Superior sensitivity and increased selectivity compared to conventional FPDs
      • Better long-term stability and less maintenance than SCD or XRF
      • Quick, easy calibrations
      • Self-cleaning design
    • Volatiles Interface
      • Optimized for ultralow dead volume flow rates, inertness, and ease of column installation

    The S-PRO 3200 System is ideal for using in demanding sulfur analysis applications, such as:

    • Sulfur content in LPG
    • COS in ethylene and propylene feedstock
    • Sulfur in natural gas
    • Impurities in beverage grade CO2
    • Semiconductor and industrial gas purity
    • Quality control in gas production and blending operations

    S-PRO 3200 Features:

    • Provides automated sample injection, calibration, and QA/QC
    • Integrated permeation oven provides single or multiple calibration or QC standards
    • Automated injection of calibration or check samples provided by the built-in valving and permeation system eliminates using unstable, expensive sulfur gas standards
    • OI Volatiles Interface, optimized for valve injection, provides low dead volume split or splitless injection for a wide dynamic range
    • Sulfinert™-treated sample pathway minimizes absorptive surfaces for optimal performance, particularly for low sulfur concentrations
    • Proven PFPD detector provides stability, sensitivity, selectivity, equimolar sulfur response, calibrations in linear or quadratic modes, and multi-element detection capability
    • Single-digit ppb sensitivity for sulfur analysis
    • Full EPC control of all injector, permeation oven, and detector gases
    • Using additional or alternative detectors (PIDELCDXSD, or tandem configurations) allows the analysis of other compounds of interest
