Introduction
A sulfur mercaptan sulfur content tester is an instrument used to measure the sulfur content and the mercaptan sulfur content of the petroleum products, the fuels, and the gases, and it is used in the petroleum, the petrochemical, the fuel, and the quality control industries. The tester measures the total sulfur content and the mercaptan sulfur content by the various methods, such as the potentiometric titration, the coulometric titration, the X-ray fluorescence, and the ultraviolet fluorescence, 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 mercaptan sulfur content tester consists of the sample introduction system, the reaction 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 mercaptan sulfur content tester is used for the measurement of the sulfur in the gasoline, the diesel, the jet fuel, and the other petroleum products, for the measurement of the mercaptan sulfur, for the quality control, for the compliance with the specifications, for the monitoring of the corrosion, and for many other applications, and it is an essential instrument for the sulfur analysis. Sulfur mercaptan sulfur content testers are used in the petroleum industry, in the petrochemical industry, in the laboratories, in the quality control, and for many other applications. With their sulfur measurement, sulfur mercaptan sulfur content testers are essential for the fuel quality control.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The mercaptan sulfur content tester is used in petroleum refineries, fuel quality laboratories and third-party testing organizations to measure mercaptan sulfur concentration in gasoline, aviation turbine fuel, diesel and other distillate products. It supports fuel specification compliance, product certification and process control where mercaptan sulfur affects odor, corrosion and stability characteristics of finished fuels.
Q2: What standards does the instrument comply with?
A: The test method follows ASTM D3227 for mercaptan sulfur in gasoline, kerosene and diesel by potentiometric titration, ISO 3012 for thiol mercaptan sulfur in middle distillates, and the corresponding GB/T 1792 method. 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 electrode, titration unit and controller are covered under the standard warranty, while titration reagents, reference solutions and electrode filling solution are consumables excluded from warranty. Electrode damage from improper storage or drying is also excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires basic laboratory training in titration technique and electrode handling. We provide an operation manual and remote guidance. Familiarity with the standard test method is recommended to ensure correct sample preparation and endpoint 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: The electrode should be calibrated with standard mercaptan solutions before each analytical batch and after electrode replacement. Full system verification with a certified reference material is recommended every 6-12 months for accredited laboratories. Electrode slope should be monitored as a performance indicator.
Q7: Are supporting consumables universal?
A: Titration reagents, reference solutions and electrolyte are available from chemical suppliers, though original reagents are recommended for consistent performance. The electrode is a specific model and should be sourced from the manufacturer or authorized distributor to ensure compatibility.
Q8: Can I customize parameters or supporting accessories?
A: Customization options include titration range, electrode type and sample handling configuration. Additional accessories such as spare electrodes, titration vessels 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, electrode 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 bulk laboratory setup projects.
Q10: What types of samples are compatible with this equipment?
A: The tester handles petroleum distillate samples within the method concentration range. Samples containing high hydrogen sulfide should be pretreated to avoid interference. Highly viscous or residue samples may require dilution with specified solvent. Corrosive or particulate-laden samples can damage the electrode and are not suitable without pretreatment.
