Contact formThe HTTS-9000 fully automatic ultraviolet fluorescence sulfur analyzer uses the ultraviolet fluorescence method to determine the total sulfur content, which improves the ability to resist impurity interference, avoids the cumbersome operation of the titration cell in the coulometric method and the unstable factors caused thereby, and greatly enhances the sensitivity of the instrument. The key components of the system adopt imported devices, and the detector is protected against light leakage and air leakage, which ensures the reliable performance of the whole machine. Application fields: environmental protection, chemical industry, biological industry, petroleum

HTTS-9000 Features of Fully Automatic Ultraviolet Fluorescence Sulfur Analyzer
The instrument adopts a vertical sampling mode.
Realize automatic cleaning of the injection needle and automatic replacement of samples, and the program can be set according to requirements.
A fully automatic sampler with 16 or more positions is selected, featuring accurate positioning. Once set, it can perform fully automatic detection and automatically set the sample injection volume, enabling unattended and automatic analysis.
The gas flow rate is precisely controlled by a mass flow meter, without the need for manual adjustment. Gas pressure and temperature are precisely controlled by responsive sensors.
The computer controls the entire process of analysis, data processing, etc., and displays the working status of the whole process. The standard curve can be completed automatically.
Imported high-quality furnace heating wires are adopted to extend the service life of the cracking furnace. The data processing software is equipped with an over-temperature protection and automatic shutdown function. When the temperature exceeds the set upper limit, the instrument will automatically cool down and enter a protection state.
The designed * fluorescent pool has an automatic compensation function for ultraviolet light source intensity, with high sensitivity and low baseline noise.
Aromatic hydrocarbon barrier filter system with a selectively permeable membrane inside, detection system, impossible to be contaminated
Special quartz cracking tube, no need for disassembly and replacement, *solves the problem that the combustion tube is prone to carbon deposition
The instrument is equipped with a gas filtration and purification system.
Abnormal gas flow rate and pressure, the instrument automatically cools down for protection.
The gas pipelines are connected with spherical clamps, which facilitates maintenance.
The instrument can set the temperature of the cracking furnace as well as the sleep and wake-up functions. After the sample analysis is completed, the instrument automatically enters the sleep state.
The key components are imported ones, which reduce the instrument noise and improve the detection sensitivity.
