Agilent Determination of boron by Graphite Furnace AAS:Comparison of different modifiers Application Note

Update: 28 September, 2023

Various modifiers were investigated regarding their influence on the characteristic mass and memory effect for boron determination by graphite furnace spectrometry. The best results were obtained using a zirconium nitrate-nickel nitrate mixed modifier, which resulted in high sensitivity (characteristic mass 200 pg), negligible memory effect, and increased tube lifetime (about 200 atomization cycles at 2800 °C). The method was successfully applied to determine boron in river water, drinking water, and sewage.
