Oxygen nitrogen hydrogen analyzer

　Oxygen nitrogen hydrogen analyzerIn order to reduce the emissions of harmful pollutants to the environment, the country has raised the quality standards for automotive fuel, reducing the sulfur content from 150ppm (National III for automotive gasoline) to 50ppm (National IV for automotive gasoline) and 10ppm (National V for automotive gasoline). The significant reduction in sulfur content has raised higher requirements for detection methods and instruments. Both National IV and National V standards for automotive fuel have introduced the "ASTMD7039 Determination of Sulfur Content in Gasoline and Diesel (Single Wavelength Dispersive X-ray Fluorescence Spectroscopy)".

Based on single wavelength dispersive X-ray fluorescence spectroscopy, our company's independently developed and produced DUBHE series single wavelength dispersive X-ray fluorescence spectrometer is the most ideal detection instrument for ultra-low sulfur content analysis. It has the characteristics of high detection sensitivity, low detection limit, fast detection speed, low usage cost, good repeatability, easy operation, and movable detection.

　　Oxygen nitrogen hydrogen analyzerMeasurement principle: Monochromatic Wavelength Dispersive X-ray Fluorescence Spectrometer (MWDXRF)

Compliant with standards: ASTMD7039, GB11140, SH/T0842-2010, ISO20884

Product Features:

Sensitivity: Highly selective detection of sulfur element, with a detection limit of 0.35ppm

Stability: XFS (X-RayFixeSystem) technology ensures the long-term stability of the instrument to the greatest extent possible, as the optical path is precisely tuned by the factory without any displacement or deviation. 5ppm gasoline sample, long-term test RSD value less than 5%

Quick: The preparation time for a single sample is less than 10 seconds; the analysis time for a single sample is as long as 300 seconds; the sample can be tested within 10 minutes of startup

Economy: The consumption of a single sample is less than 4 yuan per sample, with no consumption of gases, solvents, etc

Convenience: Using the ESP: EasySamplePrepare device makes sample cup and film formation simple; Long term use without hardware replacement; No need to frequently calibrate the standard curve

Technical Specifications:

Low detection limit: sulfur LLD=0.4ppm (300s)
