Introduction
A sulfur content tester is an instrument used to measure the sulfur content of the petroleum products, the fuels, the gases, and the other materials, and it is used in the petroleum, the petrochemical, the fuel, and the quality control industries. The sulfur content tester measures the sulfur by the various methods, such as the ultraviolet fluorescence, the X-ray fluorescence, the coulometric titration, and the combustion methods, and it provides the sulfur concentration, expressed in parts per million or in percent, with the detection limits suitable for the various applications; the sulfur content tester consists of the sample introduction system, the combustion or the detection system, the calibration, and the control and the data display, and it performs the measurement automatically, with features such as the various ranges and the data management; the sulfur content tester is used for the measurement of the sulfur in the gasoline, the diesel, the jet fuel, the crude oil, and the other petroleum products, for the measurement of the sulfur in the gases, for the quality control, for the compliance with the specifications, for the environmental monitoring, and for many other applications, and it is an essential instrument for the sulfur analysis. Sulfur content testers are used in the petroleum industry, in the petrochemical industry, in the fuel industry, in the laboratories, in the environmental monitoring, and for many other applications. With their sulfur measurement, sulfur content testers are essential for the fuel and the environmental quality control.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The sulfur content tester is used in petroleum refineries, fuel quality laboratories and third-party testing organizations to measure total sulfur concentration in gasoline, diesel, jet fuel, heating oil and other petroleum products. It supports compliance with fuel sulfur specifications, environmental emission regulations and process control in hydrodesulfurization units where low-sulfur fuel production requires accurate and repeatable sulfur measurement.
Q2: What standards does the instrument comply with?
A: The test method follows ASTM D5453 for ultraviolet fluorescence measurement of sulfur, ISO 20846 for ultraviolet fluorescence determination, and the corresponding GB/T 11060 and SH/T 0689 methods. The instrument hardware complies with relevant laboratory electrical safety standards.
Q3: What is the warranty period for the whole machine and key components?
A: The whole tester is covered by a 12-month warranty. The combustion tube, detector, furnace and controller are covered, while sample boats, reagents, catalysts and filters are consumables excluded from warranty. Damage from improper sample introduction or corrosive gas erosion is also excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained laboratory personnel familiar with the test method and instrument maintenance. We provide an operation manual, application notes and remote guidance. Structured training can be arranged for first-time users to ensure correct calibration, sample handling and result interpretation.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibration with certified sulfur standards should be performed before each analytical batch and after maintenance or reagent change. Drift verification with a check standard is recommended during long sequences. Full system calibration is required every 6-12 months for accredited laboratories.
Q7: Are supporting consumables universal?
A: Sample boats, catalysts and oxygen are available from multiple suppliers, though original consumables are recommended for combustion efficiency. Calibration standards should be sourced from accredited providers to ensure traceability. Long-term consumable cost is moderate and depends on sample throughput.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes autosampler capacity, furnace configuration and detection range. Additional accessories such as spare combustion tubes, filters and reagent sets can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the instrument and accessories with an operation manual. Remote commissioning guidance is provided. On-site installation and training are not included for standard orders but can be arranged for laboratory setup projects.
Q10: What types of samples are compatible with this equipment?
A: The tester handles liquid petroleum products within the method concentration range. Highly viscous or solid samples may require special pretreatment or solvent dilution. Samples containing high halogen or particulate matter can affect combustion efficiency and detector performance, requiring appropriate sample preparation.
