ITAN3000型定氮分析仪是由法国ADAMEL公司生产的,能快速分析钢铁中的总氮量。这里主要介绍它的性能和操作方法。本仪器采用脉冲炉,可将样品加热到3000℃熔融;氦作载气提取氮;以热导计为检测器,可测定各种钢材以及部分合金钢中的氮含量。从加入样品到显示结果,只需2～3分钟。所得结果以每克样品中含氮的微克量(ppm)表示。当样品中含氮量在10~(-4)～3%范围时,可用0.1ppm～1000ppm的灵敏度档读数;若氮含量大于上述范围,则用1ppm
ITAN3000 nitrogen analyzer is produced by the French company ADAMEL, can quickly analyze the total nitrogen in steel. Here mainly introduces its performance and operation method. The instrument uses a pulse furnace, the sample can be heated to 3000 ℃ melting; Helium as a carrier gas extraction of nitrogen; with thermal conductivity meter as a detector, can measure a variety of steel and some of the alloy steel nitrogen content. From adding samples to show the results, just 2 to 3 minutes. The results are expressed in grams of nitrogen in grams per gram of sample (ppm). When the sample contains nitrogen in the range of 10 ~ (-4) ~ 3%, available 0.1ppm ~ 1000ppm sensitivity file readings; if the nitrogen content is greater than the above range, with 1ppm
