BD-D5453-021Z fluorescence sulfur content tester, ASTM D5453

Applicable standards

ASTM D5453, D6667, D7183, GB/T17930, GB/T11060, SH/T 0689, etc.

Performance characteristics

1. BD-D5453-021Z ASTM D5453 fluorescence sulfur content tester adopts pulsed ultraviolet fluorescence analysis method, which has lower detection limit and higher detection accuracy, and can meet the detection requirements of national V and higher standard oil sulfur content.
2. Windows Chinese operating platform, direct human-machine dialogue, easy operation.
3. The computer controls the entire analysis, data processing and other processes and displays the working status of the entire process. Parameters and results can be saved or printed as needed. The software can save 5,000 sample data, and can realize historical data query and graphic playback to facilitate comparison and analysis.
4. The instrument adopts internationally popular circuits and imported components, which reduces instrument noise and improves detection sensitivity.
5. Core components: The core components of the instrument, such as membrane dryers, filters, xenon lamps, and photomultiplier tubes, are original components imported from the United States, Japan, and Europe, ensuring the quality of the instrument and the accuracy of the analysis results.
6. Using imported high-quality heating furnace wire, the cracking furnace has a longer service life. The data processing software has an automatic cut-off function for over-temperature protection. When the temperature exceeds the set upper limit, the software automatically implements power-off protection to prevent the electric furnace wire and combustion tube from being burned due to over-temperature.
7. Reaction chamber: The reaction chamber has good anti-light leakage effect. At the same time, it adopts advanced double anti-leakage (light and gas) mechanical processing technology to make the reaction chamber light-proof and sealed without air leakage, thus significantly improving the detection sensitivity and repeatability, and the measurement data results reach reached the international advanced level.
8. Analysis results: The instrument has fast analysis speed (3-4min/sample), high analysis accuracy and stability, and the repeatability error is far better than the analytical error requirements of SH/0689.
9. Single-point calibration of standard sample back standard, high pressure can be adjusted arbitrarily, no need to redo the standard curve.
10. Instrument calibration: Standard samples imported from the United States and Japan are used to calibrate the instrument to ensure the accuracy of instrument measurement, so that the instrument surpasses similar domestic products in trace measurement and accuracy.
11. Database management mode: open lims database management mode, which facilitates database retrieval and management.
