在地质样品的测试中经常遇到含钒钛的矿物,用能谱仪是无法把其中的钒同钛区分开来的.用波谱仪(即电子探针)能区分吗?有人认为,波谱同能谱一样,无法将Ti-Kβ峰与V－K_a峰区分开,前人还经常用它作为波谱分辨率极限的例子.近期在桂林召开的微束分析会议上,对此问题也作过一番争论.就连最近来我国讲学的一位加拿大矿物学家对此问题的态度也是模棱两可的.我翻阅了一些资料,又做了一些实验,事实证明近代出产的电子探针能将钒钛化合物中Ti－Kβ(L＝174.8lmm,λ＝2.514A)和 V－K_a(L=174.09mm,入=2.503A)分开(使
In the geological samples of the test often encounter vanadium-titanium containing minerals, with the spectrometer can not be one of the vanadium and titanium are separated by the spectrometer (ie, electron probe) can distinguish it Some people think that the same spectrum Like the energy spectrum, the Ti-Kβ peak can not be distinguished from the V-K_a peak, and the predecessors often use it as an example of the resolution limit of the spectrum. Recently, this issue was also made at the meeting of the microbeam analysis held in Guilin Even the most recent to our country lectures a Canadian mineralogist attitude is also ambiguous on this issue.I read some information and did some experiments proved the modern production of electronic probes can vanadium and titanium compounds (L = 174.81 mm, λ = 2.514 A) and V-K a (L = 174.09 mm, into = 2.503 A)
