Atomic Absorption Spectrometry soldering iron dust, nickel, manganese Concentration of 0.102mg / m, the average nickel in welding dust content of 0032mg / m,Moncler prezzi, the average nickel content of the helmet was 0.027mg / m; welding of iron dust in the average concentration of 3.032mg / m,oakley sunglasses, the iron helmets The average concentration of 1123mg / m. By the determination results can be seen, multifunctional protective welding helmet can eliminate the dust hazard to operators. 3.4 Using the simplex method to choose the instrument conditions optimized using simplex optimization method to select the best instrument conditions when asked and expenditure savings. Simplex method but can only choose to accelerate the absorbance as the objective function can not interfere with other multi-objective optimization objective function at the same time as the last,supra shoes outlet, Tsinghua University, Professor Deng Bo simplex has accelerated the introduction of fuzzy mathematics method, and achieved good results. Volume 3,moncler outlet, No.�� Spectroscopy Laboratory digestion rate low recovery rate of 3.5, which is part of the analyte causes the formation of insoluble silicate and silicon adsorption on the glass surface. 4 Conclusion A welding flame atomic absorption spectrometry of metals in the dust in the method, the optimized experimental conditions. Determination of the sensitivity of three elements has been significantly improved.
