Recording ? 1?Foreword?： ? SY-2000N?Chemiluminescent nitrogen detector based on principle of chemiluminescence method combined with computer technology to develop next-generation precision laboratory instruments.燱ide linear range, strong anti-jamming ability, simple, stable and reliable results, and highlight the advantages, which can be widely applied in petroleum, chemical industry, electric power, coal, food, environmental protection and other areas, is now more advanced sulfur analysis instrument. ? ? 2?The basic principle?： ? SY-2000N?Chemiluminescent nitrogen detector works as follows: ? 1?：?SY-2000N?Chemiluminescent nitrogen detector block diagram Instrument by the injector, cracking, ozone generators, reactor micro-current amplifier and, photoelectric conversion device, data processing system consists of several parts.燱hen the sample is introduced after high temperature pyrolysis reactor, mixed with oxygen combustion and quantification of nitrogen compounds into?NO, dehydration and carried by carrier gas dryer into the reaction Chamber, from ozone?O3?reaction excited?NO2cm,?Dang?NO2?﹡?When you return to the ground state, issue a photon, the light received by a photomultiplier tube and consists of micro-current amplifier, data processing systems convert the displayed a luminous intensity is proportional to the signal, by measurement of chemiluminescence intensity to derive the total nitrogen content of the sample. The entire reaction can be represented as follows: ? High-temperature ? ?  R—N＋O2?N?O＋NO?2?+?CO?2?＋H2O ? N?O＋?O3?NO2*＋O2 ? N?O2?*?NO2?＋hγ ? ? 3?Detailed technical parameters 1?Technical parameters: 1.1?Power supply voltage:AC220 v±10% 1.2?Power of the whole machine?≤?2200 W 1.3?Measuring range:?0.1ppm—1% 1.4?Detection limit:?2 NG 1.5?Repeatability:
