[12] Atomic absorption spectrometry

摘要: Publisher Summary Atomic absorption methods are the most widely used for determination of metals in biological materials. This chapter discusses an overview field to help selection among available techniques. The various elements will then be treated with recommendations preferred methodology. understanding that atomic is two techniques: flame (AAS) and furnace AAS. Flame AAS generally best analytical technique samples easily collected as solutions, if analyte concentration above mg/liter range solution. Precision about 1% routinely obtained better precision extra care taken preparation standards slightly more time-consuming used. There several problems stand way increased utilization trace metal analyses. More importantly, many analysts fail give adequate attention laboratory hygiene required at very low levels accessible by
