How much is the UV fluorescence sulfur analyzer

SH-2000SUV fluorescence sulfur analyzerProduct Overview:

Domestic integrated sulfur analysis instruments are widely used to detect sulfur content in liquid, solid, or gas samples. Compared with similar instruments at home and abroad, it has the characteristics of stable and reliable performance, high analysis accuracy, and good repeatability.

The total sulfur content in the sample was rapidly determined by UV fluorescence method. The application of high-precision data acquisition cards and computer technology provides reliable guarantees for data acquisition, control, and processing.

The instrument system uses ultraviolet fluorescence method to determine the total sulfur content, which improves the ability to resist impurity interference, avoids the complicated operation of the titration cell by the electric method and the unstable factors caused by it, and greatly improves the sensitivity of the instrument. The key components of the system are imported, ensuring reliable performance of the entire machine.

Basic Principles

The instrument adopts the principle of ultraviolet fluorescence method for measurement. When the sample is introduced into a high-temperature cracking furnace, the sample undergoes cracking oxidation reaction, and the sulfides are quantitatively converted into sulfur dioxide, which is carried by the carrier gas and dehydrated by a membrane dryer before entering the reaction chamber. Sulfur dioxide absorbs the energy of ultraviolet light and converts it into excited state sulfur dioxide (SO2 *). When SO2 * returns to the stable state of sulfur dioxide, it emits fluorescence, and the released energy is received by a photomultiplier tube. After amplification by a microcurrent amplifier and computer data processing, the luminescence intensity in the reaction is proportional to the amount of sulfur dioxide generated, and the amount of sulfur dioxide is proportional to the total sulfur content in the sample. Therefore, the total sulfur content in the sample can be determined by measuring the luminescence intensity. The entire reaction process can be expressed as follows:

S—R+O2 → SO2+SO3+CO2+H2O+ROX

SO2+hγ →SO2*→ SO2+hγ
