Microcomputer based diversified sulfur analyzerIt is a fully automatic detection device based on Coulomb titration or high-temperature combustion infrared absorption method, which achieves continuous and rapid analysis of multiple samples through microcomputer control.
Microcomputer based diversified sulfur analyzerTechnological advantages:
Dual optimization of efficiency and cost
Detection speed: The analysis time for a single sample is about 5-7 minutes, supporting continuous sample addition and significantly reducing manual intervention.
Reagent consumption: The Coulombic titration method electrolyte can be reused for 1-2 months, while the infrared method has no reagent consumption and only requires regular replacement of filter consumables, reducing long-term usage costs by 20% -30%.
Energy consumption control: The high-efficiency heating element shortens the heating time to 20 minutes, and automatically enters the insulation mode after the detection is completed, reducing energy consumption by 20% -30% compared to traditional instruments.
Accuracy and reliability
Temperature control accuracy: ± 1 ℃ (special models can reach ± 0.5 ℃), ensuring sample combustion.
Anti interference ability: The detection limit of SO ₂ by infrared method is as low as 0.001%, which is suitable for complex matrix samples such as petroleum coke and rubber.
Data management: Supports 9999 sets of historical record storage, data backup and upload, prevents tampering, and complies with ISO/IEC 17025 laboratory certification requirements.
Convenience and safety of operation
Human computer interaction: 7-inch color LCD screen or Windows operating system, providing voice broadcasting and touch sensitive buttons to lower the operating threshold.
Safety design: Silicon carbon tube automatic protection upon startup, overcurrent protection, hardware overheating alarm, to avoid equipment damage or personnel injury.
Easy maintenance: Key components such as quartz tubes and electrolytic cells are designed with modularity, eliminating the need for specialized tools for replacement and reducing maintenance time by 50%.
Key points of operation and maintenance:
Pre-experiment preparation
Check if the power supply, gas circuit, and electrolytic cell connections are tight to avoid air leakage.
Prepare electrolytes (potassium iodide, potassium bromide, glacial acetic acid) and regularly check the pH value and sulfur content.
Sample processing
Coal sample weighing: 50mg ± 0.2mg, covered with tungsten trioxide flux to prevent splashing.
Petroleum samples: 80-100mg, need to be dried to remove moisture beforehand.
routine maintenance
Cleaning the electrolytic cell: Rinse with distilled water every month to avoid black sediment affecting the detection.
Replace quartz tube: Replace every 500 tests or when cracks appear to ensure combustion efficiency.
Calibration instrument: Calibrate quarterly with standard samples to ensure data accuracy.
