In the present paper, determination of Na+, K+ and NH4+ in saliva and serum was carried out using an ion chromatography (IC) method with a bulk acoustic wave (BAW) sensor as detector and 2.0 mmol/l nitric acid as mobile phase. The IC-BAW method is simple, rapid and accurate. Comparison between the BAW detector and the conventional conductivity detector (CDD) was discussed. The IC-BAW showed agreement with the commonly used flame photometric method for Na+ and K+ and enzymatic method for NH4+, as well as IC-CDD for those three cations.
在本论文中,采用离子色谱(IC)法,以体声波(BAW)传感器作为检测器,2.0 mmol/l硝酸作为流动相,对唾液和血清中的Na+、K+和NH4+进行了测定。离子色谱-体声波法简单、快速且准确。讨论了体声波检测器与传统电导检测器(CDD)之间的比较。离子色谱-体声波法对Na+和K+的测定结果与常用的火焰光度法一致,对NH4+的测定结果与酶法一致,对这三种阳离子的测定结果与离子色谱-电导检测器法一致。
