The paper presents the layout, the technological steps and the measurement results for an interdigital integrated capacitor used for gases detection. Silicon micromachining technology is applied for manufacturing the sensor substrate. The sensitive layer used is phthalocyanine (Pc) deposed by EDL (evaporated dyes layers technique). Many solutions were found as phthalocyanine derivatives deposition technique. Considering the different sensitivities

The in vitro release of trichlorphon (TCP) from acidic solutions was studied using a static diffusion cell battery, through cellulose membranes. The amount of toxic released compound decreases in the following order: cellophane (83%), cuprophan (78%) and cellulose acetate (74%). There was also studied the influence of adsorptive powders upon the decreasing amount of the released compound. We observed that the powder mixture cellulose acetate: bentonite

he paper presents the manufacturing and testing of resistive integrated microsensors, using as sensitive and conductive layer copper and zinc phthalocyanines, used for the detection of NO2 and NOx in polluted atmosphere, at room temperature. The measurement of the phthalocyanine chromogene layers deposited by vacuum sublimation on electrodes showed, generally, high values of the measured resistance which decreases significantly in the presence of

The objectives of this study were the development and validation of an extraction method for the simultaneous HPLC determination of Tramadol and its active metabolite o-desmethyltramadol (M1) in plasma in order to use it in bioequivalence studies. A reversed-phase mechanism with fluorescence detection and liquid/liquid extraction from basic plasma samples were chosen for the determination of Tramadol and M1. The bioequivalence study was made for

The objectives of this study were to develop and validate a method for the simultaneous HPLC-UV determination of obidoxime (OBI), scopolamine (SCA), Atropine (ATR) and imipramine (I) in an aqueous antidote solution. An ion-pair mechanism with DAD (diode array detector) detection was used to quantitatively determine the four drugs. The proposed HPLC method uses a Kromasil 100-5C8 (250x4.6mm) column, gradient elution, at 25°C column temperature. The
