Fluorescence sulfur analyzer temperature control(Long)×wide×High)：500mm×400mm×400mm

Quartz cracking tube

Sulfur nitrogen chlorine blind sleeve quartz cracking tube improves the detection accuracy of the instrument. The tail end of the quartz tube is equipped with an original filter membrane.

Gas stabilization system

A pressure stabilization system has been installed in the gas circuit to avoid interference from fluctuations in gas pressure on the measurement

Temperature control system

Adopting a vertical combustion furnace and vertical injection analysis mode; The original heating furnace wire and cracking furnace have a longer service life.

Automatic control device for cracking furnace fan, automatic on/off of cooling fan, with delayed shutdown function, automatically shuts down after the electric furnace cools down，No need for personnel to wait for shutdown

Testing room

Sulfur reaction chamber device,Targeting the countryThe low sulfur detection of VI oil products uses a light sealed reaction chamber without air leakage, and the measurement data results meet national standards.

Analysis system

The computer controls the entire process of analysis, data processing, etc., and displays the working status of the entire process.

Fast instrument analysis speed(3～4 minutes/sample), accurate and stable analysis, with repeatability error better than the analysis error requirements of SH/0689.

drying system

Imported from the original factoryMembrane dryer, no need for frequent replacement, stable performance.

Key components

Using original circuits and components;The main accessories such as membrane dryer, filter, xenon lamp, and photomultiplier tube are original factory parts, ensuring the quality of the instrument and the accuracy of the analysis results，Stable and reliable performance, high detection accuracy.

Mass flowmeter

useQuality flow meter, computer-controlled gas flow rate, with no fluctuations, stable and accurate gas flow rate.The instrument has better repeatability and higher measurement accuracy for small content samples.

Gas generator

Using a gas generator to provide gas source, without the need for argon or oxygen cylinders;

Protection function

Equipped with over temperature protection and automatic cut-off function, when the temperature exceeds the set limit *, the software automatically implements power-off protection to prevent the electric furnace wire and combustion tube from being burned out due to over temperature.

It has a gas flow alarm function. When the gas flow is abnormal, the software automatically shuts off the injection function and prevents carbon deposition.

Sample injection system

Syringe injection system

The injection speed is constant and can be adjusted according to the sample

software system

data processing

Adopting multiple standard curves that can be set arbitrarily; Single point calibration of standard sample, high voltage can be adjusted arbitrarily, no need to redo the standard curve.

It has the function of automatic calculation of concentration and content, displaying parameters, measurement peak shape and measurement results on the screen, and can be stored or printed，Software can save5000Sample data can be queried for historical data and played back graphically, making it easy to compare and analyze.

Instrument calibration: The original factory standard sample is used for instrument calibration to ensure the accuracy of instrument measurement.

data display

Parameter setting, calibration, and sample testing are performed on the same interface

operating platform

Windows operating platform with human-machine dialogue function,Can meetLIMS system compatibility requirements.The analysis process and data processing process are controlled by computers, making operation convenient. Computer displays parameters, analyzes curves, and analyzes data.
