Atomic distributions in acetylene-air flame using hydraulic high-pressure nebulization with direct (100%) introduction of solutions Applications to speciation analysis
چکیده انگلیسی
One of the fundamental factors of the performance of atomic spectrometric methods is the efficiency of sample introduction into flame or plasma. By utilization of the formerly developed hydraulic high-pressure nebulizer, a nebulizer/burner system with solution uptake efficiency of 100% have been worked out. Optimizing operation parameters of nebulizer/burner system, an improvement of 2-12 times was achieved for the signal-to-noise ratio in the flame emission and flame atomic absorption spectrometry, depending on sample flow rate. This nebulizer is especially suitable for development of liquid chromatography-AAS/FES coupled technique for speciation analytical tasks.
