TLSN-30A sulfur and nitrogen analyzer (automatic injection)

Product Usage: Suitable for determining the content of total sulfur and total nitrogen in crude oil, hydrocarbons, engine fuels, petroleum gas, plastics, petrochemical products, food, and other samples

Applicable standards: Developed and produced according to standards such as ASTM D4629, SH/T 0689, ASTM D5453, SH/T 0657, etc

Instrument principle: The instrument adopts the principles of ultraviolet fluorescence measurement and chemiluminescence detection. When the sample is introduced into a high-temperature cracking furnace, the sample undergoes cracking and oxidation reaction. The sulfides in the sample are quantitatively converted into sulfur dioxide, and the nitrides are quantitatively converted into nitric oxide. It is carried by the carrier gas and the moisture is removed through a membrane dryer before entering the reaction chamber. After being excited by an excitation source, corresponding wavelengths of light are released, and the content of total sulfur and total nitrogen is detected by a phototransistor.

Sample like body: can measure gases, liquids, or their -.

Functional features:

 Flow rate control: Using imported mass flow meters, PID algorithm automatically adjusts the flow rates of carrier gas and cracking gas.

Six position fully automatic multifunctional gas sampler, realizing fully automatic injection of six position gas samples, automatically switching to sampling position, pipeline backflushing, sample sampling, and sample injection process.
