Sulfur Analyzer PETRA 4294

Petra 4294 is a high-precision XRF analyzer that delivers ASTM D4294 sulfur analysis across a broad measurement range. This instrument offers advanced precision with HDXRF, advanced reliability, and advanced software and data management. Petroleum laboratories depend on reliable, robust analytical solutions for their fast-paced environment. Petra 4294 was designed to meet these needs with an innovative sample introduction system that directs accidental spills to a drip tray and away from valuable components.
The Petra series complies with ASTM D8252, ASTM D4294 and ISO 8754 for sulfur analysis in various hydrocarbon matrices. Petra 4294™ delivers precise sulfur analysis with limits of detection (LOD) as low as 2.6 ppm. Petra MAX™ delivers a sulfur LOD as low as 5.7 ppm with rapid monitoring of critical elements like Ni, V, and Fe at sub-ppm levels.



Petra 4294 Autosampler offers a more efficient workflow with sample tracking and continuous sample loading. Users can eliminate data errors and add urgent samples to the queue as needed. The 8-position sample slide offers continuous loading, allowing you to add urgent samples to the queue even during analysis.

The Autosampler Upgrade Kit can be added to any Petra Series analyzer. Users have the option to use X-ID Sample Cups (QR-coded) or standard XRF cups.

Sulfur Analyzer PETRA MAX

Petra MAX delivers a sulfur LOD as low as 5.7 ppm with rapid monitoring of critical elements like Ni, V, and Fe at sub-ppm levels. Method Compliance ASTM D4292, D8252, ISO 8754 & IP 336

Petra is powered by High Definition X-ray Fluorescence (HDXRF®) technology: an elemental analysis technique offering significantly enhanced detection performance over traditional XRF technology. This technique applies state-of-the-art monochromating and focusing optics, enabling dramatically higher signal-to-background ratio compared to traditional polychromatic X-ray Fluorescence.

The blending of crude oils from different sources has become more commonplace within the industry to meet specifications for the classification of sweet crude oil. The introduction of new crudes brings new challenges, like higher concentrations of metals such as nickel (Ni), vanadium (V), and iron (Fe). Ni and V are known to rapidly deactivate process catalysts in the catalytic cracker (FCC) and hydrotreaters. In response, many refiners have incorporated Ni and V analysis into their routine crude assay, and pipelines have set specifications for Ni and V in their common stream sweet crude. Fe is introduced into crude oil from corrosion byproducts during transportation and can lead to pump and exchanger fouling, and off-specification coke.
