日本宇都宫制作所新研究出一种同时快速定量金属中氧、氮及氢的装置,其外观示于图1。用该装置同时定量三成分约需7分钟,灵敏度为0.1Ppm,精度 O 与 N 的σ为2.5ppm,CV为2.5%;H 的σ为o.4ppm,CV 为4%。测定范围为0～2000ppm。测定原理:试样放入石墨坩埚中,直接通 Japan’s Utsunomiya Institute has developed a new rapid simultaneous determination of metal oxygen, nitrogen and hydrogen devices, the appearance of Figure 1. With this device, it takes about 7 minutes to quantify the three components at the same time. The sensitivity is 0.1Ppm. The accuracy of O and N is 2.5ppm and the CV is 2.5%. The σ of H is 0.4ppm and the CV is 4%. The measurement range is 0 ~ 2000ppm. Determination principle: the sample into the graphite crucible, direct pass
