اسپکتروفتومتری جذب اتمی (AAS)
طیف سنج جذب اتمی(AAS) Atomic Absorption Spectrometer یک روش طیف سنجی برای اندازه گیری مقدار عناصر شیمایی ، حاصل از جذب نور اتم در حالت گازی است .برای اندازه گیری مقدار یک عنصر در نمونه کار برد دارد. مبنای این روش جذب تشعشات الکترومغناطیس اتم های یک عنصر است . از این روش در شناسایی بیش از 70 عنصر استفاده می شود اما دقت در عناصر مختلف متفاوت می باشد
