New and Improved Technology
OI Analytical’s patented* Pulsed Flame Photometric Detector (PFPD) is the key to our success in detecting and measuring sulfur contaminants. Our Model 5383 PFPD has a linear, equimolar response enabling the unique capability to obtain simultaneous sulfur and hydrocarbon chromatograms from a single PFPD detector.
Sulfur in Stealth Mode
Sulfur compounds can be incredibly difficult to detect, causing significant problems if unnoticed. Take propylene, a co-product from steam cracking of ethylene, as an example. Carbonyl sulfide (COS) is a major contaminant in propylene feedstock and can destroy expensive catalyst beds used in polymer production and other processes if not removed.

Hassle-free Refractometry Method Provides More Reliable Analysis
The measurement of refractive index is commonplace within the petrochemical industry and its determination is cited in many technical documents and standard test methods such as ASTM D2140 for calculating the carbon-type composition of insulating oils.
Refractometer manufacturer, and Xylem Analytics sister brand, Bellingham + Stanley has established a method within their latest RFM900-T Series instruments that (once all parameters are known) automatically calculates and displays the relevant information on the instrument display and/or printed report. This eliminates the frustration of manual
interpretation and provides far more reliable results,
especially if different operators are involved in the process.
