Graphite furnace atomic absorption spectrometry of arsenic in urine by Li Jian Feng graphite furnace atomic absorption spectrometry is a common method for determination of arsenic in urine. Phosphate and uric acid in the urine of salt interference, the determination has led to great difficulties. If the ashing temperature is too low, not easy to eliminate interference, ashing temperature, the sample and the graphite tube, easy loss short life. In order to find a sensitive, accurate, simple,[link widoczny dla zalogowanych], fast, low cost, large quantities of samples for analysis, we graphite furnace atomic absorption spectrometry method for determination of arsenic in urine were more in-depth research,[link widoczny dla zalogowanych], and conducted a quality control. I. Materials and Methods 1. Instruments: the United States for a 800 PE Zeeman effect atomic absorption spectrometer, 800 transverse heated graphite furnace atomizer, AS a 800 autosampler, arsenic electrodeless discharge lamp and pyrolytic graphite tube LVOV Room Author: 200032 Shanghai Fudan University School of Public Health Occupational Health Training and Research
