XOS Petra MAX & Petra 4294 Analyzer


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.

Multi Elemental Analysis

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.

Petra MAX offers advanced precision with HDXRF, advanced reliability, and advanced software and data management. Petra boasts an innovative autosampler design and advanced software features for a more flexible and efficient workflow.
