国产原子吸收石墨炉仪大都以手动进样为主,由于进样位置难以固定,分析精度低,且与操作人员熟练程度有着极大关系。 在工作实践中根据所使用的石墨炉加工制作了一只进样定位器(见图1)(与北二光WFX—1D石墨炉配套使用),方便适用,基本解决了测定精度低的 Most domestic atomic absorption graphite furnace mainly manual injection, the injection position is difficult to be fixed, the analysis accuracy is low, and has a great relationship with the operator proficiency. In practice, according to the use of graphite furnace processing produced a sample positioning device (see Figure 1) (with the North Second Light WFX-1D graphite furnace supporting the use of), easy to apply, the basic solution to the low measurement accuracy
