“…Recently, the application of BAW sensor as a conductivity detector of LC has been reported. 16,[21][22][23] The BAW detector used in this work is a simple home-made one. In theory, a BAW detector has substantial advantages in many aspects over a conventional conductivity detector (CCD).…”

“…16 Furthermore, the temperature coefficient of the crystal frequency increases with increased background electrolyte. 22 It is observed from experimental data that noise and drift levels of the BAW detector increase when temperature difference between the BAW detector and the chromatographic column elevates, and they are minimal when the BAW detector temperature is similar to that of the column.…”

Based on the impedance behavior of red cell at high frequency, the frequency response of series piezoelectric crystal sensor in the red cell suspension was derived and verified experimentally. A method of using piezoelectric crystal sensor to determine the conductivity of the interior of the cell was proposed. The experimental results show that the mean conductivity of rabbit red cell cytoplasm was 0.269 S/m and the mean shape factor of red cell was 2.05.

SummarySalicylate is a hydrolysis product of salicylate-containing drugs (such as aspirin) in patients' blood. Monitoring of this ion in blood is helpful for diagnosing of overdosage of these drugs. The present paper describes an ion chromatography (IC) method developed for determination of total salicylate in human serum, in which a bulk acoustic wave (BAW) sensor was used as detector; 0.5 mmoYL sodium carbonate (Na2C03, pH 8.5) served as mobile phase. Interference in the determination was negligible. The method is simple, rapid, accurate, and precise. Serum salicylate was analyzed using both the proposed IC-BAW method and the classical Trinder spectrophotometric method, and the results showed that the two method agreed well.
