KN-5453A Automatic Ultraviolet Fluorescence Sulfur Tester

Overview

KN-5453A Automatic Ultraviolet Fluorescence Sulfur Tester conforms to ASTM D5453 Standard Test Method for Determination of Total Sulfur in Light Hydrocarbons, Spark Ignition Engine Fuel, Diesel Engine Fuel, and Engine Oil by Ultraviolet Fluorescence. ASTM D6667 Standard Test Method for Determination of Total Volatile Sulfur in Gaseous Hydrocarbons and Liquefied Petroleum Gases by Ultraviolet Fluorescence and ASTM D7183 Standard Test Method for Determination of Total Sulfur in Aromatic Hydrocarbons and Related Chemicals by Ultraviolet Fluorescence. It adopts advanced total sulfur analysis method--ultraviolet fluorescence method, determine the total sulfur content of various kinds of gas, liquid, solid oils and chemical product. It is an apparatus with high sensitivity, stable property, low detection lower limit, accurate test result, good repeatability.

Features

1. Windows operation platform, computer controls analysis, data processing and other processes, display the working status of the whole process; test parameters and results can be saved or printed; historical data query and graphic playback can be realized, which is convenient for comparison and analysis.

2. Adopts the latest internationally popular pulsed ultraviolet fluorescence analysis method, which can effectively avoid the unstable sampling value caused by the attenuation of the ultraviolet lamp signal by modulating and demodulating the light source signal. Lower detection limit and higher accuracy. Be able to meet higher standard oil sulfur content testing requirements.

3. Automatic replacement of CRM or sample, automatic cleaning, automatic elimination of air bubbles, automatic standard curve drawing, etc.

4. Standard sample single-point reverse calibration, high pressure can be adjusted arbitrarily, no need to redo the standard curve.

5. Reaction chamber: For the low-sulfur detection, we have made major adjustments to the structure of the reaction chamber. The reaction chamber has a good anti-leakage effect. At the same time, the double leakage-proof (light and gas) processing technology is adopted to protect the reaction chamber from light. Sealed without air leakage, so that the detection sensitivity and repeatability are significantly improved, and the measurement data results have reached the international level.

6. Gas cut-off protection function: If the gas source pressure is unstable, the tester will automatic shutdown to avoid system pollution.

7. Adopts imported high-quality heating furnace wire, the cracking furnace has a longer service life

8. The imported xenon lamp is used as the ultraviolet light source to replace the traditional zinc lamp. The zinc lamp is easy to decay and needs to be replaced every 1-2 years. The service life of imported xenon lamps is more than 5 years, and the good stability ensures the accuracy of detection and greatly reduces maintenance costs.

9. Core components: Membrane dryer, filter, xenon lamp, photomultiplier tube, sampling needle and other main components are the original components imported from the United States, Japan and Europe, which ensure the quality of the instrument and the accuracy of the analysis results.

10. Equipped with 50ul imported injection needle, the injection volume is adjustable.

11. Apparatus calibration: CRM imported from the United States and Japan for calibration to ensure the accuracy of measurement.

12. Database management mode: Open lims database management mode, which is convenient for database retrieval management

13. Mass flowmeter is optional
