ABSTRACT
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.
