Flow-injection catalytic determination of molybdenum with blamperometric detection in a microprocessor-controlled system

Ion‐sensitive field‐effect transistors and ion‐selective electrodes as sensors in dynamic systems

“…d) In short, flow-through ISFETs arrangements have been applied in on-line blood electrolyte monitoring (1081, in biotechnology [ 1241, in the measurement of environmental parameters [117, 1231, but especially in clinical analysis for determining parameters in serum [114, 1291, in blood [l lo], and for in vivo blood monitoring [112]. On the other hand, flowthrough ISE approaches have been used more in environmental monitoring, especially for water samples: freshwater [67], natural water [43,76,791, tap water [27,47,50,84,88, 931, seawater [63], wastewater [52, 74, 761, and effluents [77, 781, but also for soils [39,44,981 and rock salts (431. Also the clinical applications of ISEs working in flowing systems are numerous: serum [31,33,34,35,421, plasma [37], blood [68], and urine [84] have been the commonest target samples.…”

Biamperometric Determination of Tetracycline in Pharmaceuticals

“…Biamperometry is a well-suited technique for electrochemical detection in flow analysis. Biamperometric detection flow cells can be easily assembled (Trojanowicz et al 1986) and, allied to the easy control of the detection conditions, the required instrumentation is quite simple (Tougas et al 1985).…”

Flow-Injection Biamperometric Direct Determination of Hydrazine at Two Oxide-Modified Platinum Electrodes

“…As has been shown (17)(18)(19)(20)(21)(22)(23)(24), biamperometric detector with two identical platinum electrodes polarized with a small potential difference is useful in flow injection analysis. Based on the principle of biamperometric endpoint detection the detector shows high sensitivity, Moreover, because the potential difference imposed is very small (usually < 200 mV), the detector shows high selectivity.…”
