Benchtop Sulfur Analyser in Petroleum Products by
X-Ray Fluorescence Spectrophotometer Model XRF-S
Key Features:
- Benchtop design for on-site or lab use for Sulfur in Petroleum Products
- Small foot print with PC connection
- Complies with ASTM D4294, ISO8754, ISO20847 and IP336
- No sample preparation required
- The sample cup is designed of the same height, which ensures the measurement data to be accurate and saves the consumption of the standard sample and the gas.
- Small sealed helium gas sample chamber saves gas consumption and reduces test costs
- Shortest sample distance on top of detector improves test accuracy
- Rapid analysis with test result delivered within 50s at minimum
- Small quantity sample size without special handling tools
- High excitation efficiency side-window with W target X-ray tube
- Large area SDD detector, together with good dissipation capability ensure the high test stability
- X-ray radiation shielding design ensures operators safety during operation
- Easy to use software with both qualitative and quantitative analysis
