Poly 3-methylthiophene (P3MT) modified electrodes have shown an improvement for detecting catecholamines when compared to classical ones. Past work with this polymer electrode suggested the possible presence of “active sites,” which are believed

This work reports the electrochemical detection of catechol (10 −4 to 10 −6 M) in the presence of ascorbic acid (10 −4 to 10 −6 M) using dual-band poly(3-methylthiophene) (P3MT) electrode flow-injection amperometry without prior separation. T

The incorporation of free transition metal cations (potential redox catalyst centers) into conducting organic films by electrodeposition is relatively rare due to the repulsive nature of the positive cation radicals of the polymer itself during polym

Prior studies have shown that poly(3-methylthiophene)-modified platinum electrodes (P3MT/Pt) have improved electrochemical reversibility, selectivity, and sensitivity for the detection of catecholamines when compared with conventional electrodes. Dif

The electrocatalytic effect of the conducting poly(3-methylthiophene) film (3-PMT) electrode on the redox behavior of catechol compounds has been examined. The nature of the electrode material substrate had no effect on the peak potentials in the cyc

Preconcentration of multi-element volatile hydrides in a graphite furnace and the subsequent determination by inductively coupled plasma mass spectrometry (ICP-MS) is a relatively new method for elemental analysis. This method offers several advantag
