Novel miniaturized polyurethane (PU) membrane sensors in an all-solid state graphite support were developed, electrochemically evaluated and used for the assay of thiopental drug. The thiopental (T) sensors are based on the formation of ion-association complexes of thiopental with copper(II) and cobalt(II)-bathophenanthroline (bphen) counter anions as electroactive materials dispersed in a poly...

The construction and electrochemical response characteristics of PVC membrane and coated wire sensors for the determination of Benzydamine hydrochloride (Benz) are described. PVC membrane sensors, include sensors 1, 2 and 3, and coatedwire sensors include sensors 4, 5 and 6. Sensors 1 and 4 based on benzydamine phosphotungstate (Benz-PTA) as ion-pair, sensors 2 and 5 based on benzydamine phosph...

For most chemists, potentiometry with ion-selective electrodes (ISEs) primarily means pH measurements with a glass electrode. Those interested in clinical analysis might know that ISEs, routinely used for the determination of blood electrolytes, have a market size comparable to that of glass electrodes. It is even less well known that potentiometry went through a silent revolution during the pa...

Serum consists of water (93% of serum volume) and nonaqueous components, mainly lipids and proteins (7% of serum volume). Sodium is restricted to serum water. In states of hyperproteinemia or hyperlipidemia, there is an increased mass of the nonaqueous components of serum and a concomitant decrease in the proportion of serum composed of water. Thus, pseudohyponatremia results because the flame ...

The acid-base equilibrium of lorazepam was studied by means of potentiometry andmultiwavelengths spectrophotometry. The stoichiometric equilibrium constants were determinedat 25 °C and constant ionic strength 0.1 mol L-1 (NaCl). The acidity constants pK1=1.58±0.05and pK2=11.67±0.07 were found by potentiometry, and pK1=1.54±0.02 and pK2=11.61±0.03 bymulti-wavelengths spectrophotometry. Potentiom...

In a lot of systems, charge transport is governed by local features rather than being a global property as suggested by extracting a single resistance value. Consequently, techniques that resolve local structure in the electronic potential are crucial for a detailed understanding of electronic transport in realistic devices. Recently, we have introduced a new potentiometry method based on low-e...
