Single-Wavelength X-ray Fluorescence (SWXRF)

PeDX SW6 Portable Ultra-Low Sulfur Oil Analyzer

PeDX SW6 Portable Ultra-Low Sulfur Oil Analyzer

Driven by tightening global sulfur cap regulations and domestic clean fuel standards, the PeDX SW6 portable ultra-low sulfur oil analyzer sets a new benchmark for rapid on-site and laboratory sulfur detection.


Powered by advanced single-wavelength excitation technology, it effectively suppresses background interference, delivering exceptional signal-to-noise ratio and detection sensitivity. Compared to conventional XRF, the PeDX SW6 achieves breakthrough performance with low background and high excitation efficiency, enabling precise quantification of light elements like sulfur at ultra-low levels.


Compact, easy to operate, and fast, the PeDX SW6 is ideal for on-site sulfur screening in gasoline, diesel, jet fuel, ethanol gasoline, residual oil, lubricating oil, crude oil, and more. It is a trusted tool for environmental and transportation law enforcement, as well as petrochemical quality control, warehouse inspection, and trade settlement.


Advantage

Single-Wavelength X-Ray Fluorescence Technology

Based on an advanced doubly curved crystal (DCC) design, this technology significantly reduces background noise and greatly improves the signal-to-noise ratio, delivering more accurate and stable analytical results for the product.

Wide-Range High-Precision Multi-Element Analysis

The instrument combines a wide dynamic range with high precision. It not only enables rapid and accurate analysis of ultra-low sulfur content but also supports fast detection of multiple elements from Mg to Ca. It is especially suitable for high-sensitivity analysis of key elements such as Ca, K, Cl, and P at ppm levels.

Simple Sample Preparation

Sample preparation is simple and easy to operate, requiring no complex pretreatment. The integrated sample cup and sample film are used as a complete set, eliminating the need for manual film attachment on-site. This avoids errors introduced during sample preparation and prevents sample contamination.

One-Key Intelligent Operation

The interface design is intuitive and user-friendly, enabling one-key operation throughout the entire process of "sample loading — measurement — reading." An built-in intelligent guidance system and automatic diagnostic functions allow quick operation without a professional background, effectively eliminating human errors and significantly improving on-site testing efficiency.

Lightweight and Portable

The instrument is lightweight and compact, with an ergonomic design and strong battery life, making it suitable for field/on-site application testing requirements.

APP Cloud Service

The device is equipped with a mobile APP service that enables synchronized control. The mobile APP allows operation, transmission, and management of data, labels, and other information, easily achieving system data interfacing and sharing.

User Customization

Test reports can be exported in formats such as EXCEL and PDF. Users can create custom test reports that include company logos, spectra, and other sample information.
