| Abstract: | Determination of trace chromium in leaf was studied in direct soild sample injection by flamelcss AAS. According to the Character of Varian GTA-95 graphit furnace atomizer, we designed the solid micro sampler and sampling fixer. It was shown that the accuracy and reproducibility of the method were satisfactory. And the oparation was simple. |
