Fast analysis with Zeeman graphite furnace AAS

摘要: Abstract Stabilized Temperature Platform Furnace (STPF) methods have been adapted and altered to reduce the analytical time less than 1 min per sample with no loss of precision or accuracy. It is shown that this could be further reduced about 30 s if certain changes in instrumentation are implemented, especially software firmware control autosampler. The uptake rate for autosampler should overlap cooldown tube from prior determination. Also, deposited onto a heated platform. In work pyrolysis step and, most cases, use matrix modifier has omitted. Since backgrounds were therefore larger, Zeeman correction was usually required, but continuum background not tried. To confirm these fast might practical, more 10 standard reference materials analyzed several elements including Pb, Cd, Cu, Ni, As Cr. paper primarily intended provide routine reliable methods; it test feasibility methods.
