摘要：制作了一个三电极电致膜抑制器,考察了加电方式、串连电阻阻值、电极间距对改善噪声的影响。相较于传统两电极抑制器,优化得到的三电极抑制器在抑制CO32--淋洗液时在噪声(~2.5倍)和信噪比(2.5~3.6倍)方面皆有一定程度的改善;所得三电极抑制器稳定性好,可与离子色谱结合后检测饮料中6种常见阴离子含量。
A three-electrode electrodialytic membrane anion suppressor( t EMS) was fabricated,the effects of charging way,resistance value of serial resistance and the gap of two cathodes on noise reduction were studied.Compared with the conventional two-electrode counterpart,tEMS showed ~2. 5 fold lower noise level,as well as 2. 5-3. 6 fold higher signal and noise ratio towards common inorganic anions. The obtained t EMS has good stability and could be used to determine six inorganic anions in several types of drinks.
