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
- The 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 use 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 offers single or multiple calibrations 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.
- A 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
- Complete EPC control of all injectors, permeation oven, and detector gases
- Using additional or alternative detectors (PID, ELCD, XSD, or tandem configurations) allows the analysis of other compounds of interest
