The possibilities of use of a graphite oven type HGA 74 (Perkin Elmer) for the estimation of aluminium in biological fluids by atomic absorption spectrophotometry are described, with a special study of the stages of drying, mineralisation, atomisation, flow of inert gas, requirement for correction of non-specific absorption, etc. Under fixed experimental conditions, the limit of sensitivity (absorption 1%) was 2.28.10.(-11) grams and the linearity was good up to 100 microgram/l. This method of analysis by direct treatment of the samples required only small volumes of the latter and reduces the risk of contamination.
描述了使用石墨炉HGA 74型(珀金埃尔默公司)通过原子吸收分光光度法测定生物流体中铝的可能性,并特别研究了干燥、矿化、原子化、惰性气体流量、非特异性吸收校正要求等阶段。在固定的实验条件下,灵敏度极限(吸光度1%)为2.28×10⁻¹¹克,线性在高达100微克/升时良好。这种直接处理样品的分析方法仅需要少量样品,并降低了污染风险。
