摘要
本文报道一个以中性载体ETH1810为活性材料的锂离子选择性液膜微电极,对钠和钾离子的选择性系数分别为-2.0和-2.4(对数值),端径为1μm,内阻为1.2×10^(10)Ω,可用于细胞内外锂离子活度的测定。
A lithium-selective microelectrode based on the neutral carrier, ETH 1810, as an active reagent was described. The selectivities of lithium, e. g., log K_(Li,N_2)^(Pto)=-2.0, logK_(Li,K)^(Pot)=-2.4, were obtained. The measurements using this microelectrode in serum sample were presented.
