用纯仪器中子活化分析法测定吉林地球化学水系沉积物Ⅱ级标样GRD30～46,是在我室测定我国首批地球化学标样系列GSD1～8时所制定的技术方法的基础上进行的。对吉林标样GRD30～46共测得21种元素。 吉林标样共照射3次,每次照射标样均制成双份,目的在于从中检验标样的平行性。此标样的标准用美国地调所的GXR,测得的γ能谱由PDP-11/04型计算机按Spectran-F分析软件包给出分析结果,再由我室自编的
Using pure instrumental neutron activation analysis method to determine grade Ⅱ GRD30 ~ 46 of geochemical sediments in Jilin Province was based on the technical method developed in our laboratory when determining the first batch of geochemical standard series GSD1 ~ 8 in our country . Jilin standard GRD30 ~ 46 were measured 21 kinds of elements. Jilin standard samples were co-irradiated 3 times, each irradiation standard were made in duplicate, the purpose is to test the standard parallelism. This standard standard with the United States to adjust the GXR, the measured γ-spectrum by the PDP-11/04 computer by Spectran-F analysis package gives the analysis results, and then by my room
