Electricity method bromine valence bromine index tester

The bromine value and bromine index of the sample can be calculated by injecting the sample into the titration cell using the electric quantity method. Unsaturated hydrocarbons in the sample undergo an addition reaction with bromine in the electrolyte. By calculating the amount of electricity consumed by generating bromine, the bromine value and bromine index of the sample can be determined according to Faraday's law of electrolysis.

Chemiluminescence nitrogen analyzerModel: THA-6000N
Overview:

The instrument adopts the principle of chemiluminescence detection. After the test sample (or standard sample) is introduced into the high-temperature cracking furnace, at a high temperature of around 1000 ℃, the sample is vaporized and undergoes oxidative cracking, where the nitrogen compounds are quantitatively converted into nitric oxide (NO). The reaction gas is carried by the carrier gas, and after passing through a membrane dryer to remove its moisture, it enters the reaction chamber. The metastable nitric oxide reacts with O3 gas from the ozone generator in the reaction chamber, converting into excited NO2 *. When the excited state of NO2 * transitions to the ground state, photons are emitted, and the light signal is detected and received by a photomultiplier tube at a specific wavelength. After amplification by a microcurrent amplifier and computer data processing, it can be converted into an electrical signal proportional to the intensity of light. Under certain conditions, the intensity of chemiluminescence in the reaction is proportional to the amount of nitric oxide produced, and the amount of nitric oxide is proportional to the total nitrogen content in the sample. Therefore, the total nitrogen content in the sample can be determined by measuring the intensity of chemiluminescence.

Scope of application: Suitable for determining the total nitrogen content in crude oil, distillate oil, refined oil, petroleum gas, crude benzene, refined benzene, plastics, petrochemical products, food, and wastewater.
Compliant with standards: Compliant with SH/T0657, ASTM D4629, ASTM D5762, GB/T17674 and other standards.
