摘要：
The problems encountered in the determination of trace elements in small sample volumes of the order of 1 to 10 mu l (e.g. in droplets of water) are discussed. Total reflexion X-ray fluorescence (TXRF) and neutron activation analysis (NAA) are applied for the determination of Na, Mg, K, Ca, Mn, Fe, Co, and Cu in concentrations of 0.01 to 10 mg/L in 1 to 10 mu L of water. The applied methods are described, the results are discussed and the advantages of TXRF are brought forward.
