■ Product use: Suitable for measuring crude oil, hydrocarbons, engine fuels, petroleum gas, plastics, petrochemical products, food and other samples
The content of total sulfur and total nitrogen in the product.
Applicable standards: Developed and produced according to ASTM D4629, SH/T 0689, ASTM D5453, SH/T 0657 and other standards
■ Instrument principle: The instrument adopts the principles of ultraviolet fluorescence measurement and chemiluminescence detection. When the sample is introduced into the high-temperature cracking furnace
Afterwards, the sample undergoes a cracking oxidation reaction, where sulfides are quantitatively converted to sulfur dioxide and nitrides are quantitatively converted to oxygen
Nitrogen is carried by a carrier gas and removed from its moisture by a membrane dryer before entering the reaction chamber. After being stimulated by the excitation source, release the corresponding
Fluorescence of wavelength is used to detect the content of total sulfur and total nitrogen through a photomultiplier tube.
■ Functional features: ◇ Flow rate control: Adopting imported mass flow meters, PID algorithm automatically adjusts the flow rate of carrier gas and cracking gas.
◇ Injection method: 19 position fully automatic sampler
