超低硫燃料单色 WDXRF 硫分析仪
Labs that want sub-mg/kg sulfur numbers without running a combustion furnace often pick monochromatic WDXRF. Doubly curved crystal optics give detection near 0.4 mg/kg over a 0.4–500 mg/kg span, per ASTM D7039 and ISO 13032. Each reading takes 200–300 s in a disposable thin-film cell, and a changer of up to 12 positions is available.
