A specialized version of the Model CV-27 Voltammograph (Model CV-37) is designed for use with microelectrodes and their associated low currents (nA range). For mote advanced electrochemical measurements BAS provides the Model 100B/W Electrochemical Workstation, which allows one to carry out almost any modem electrochemical measurement with digital electronics and computer control. 

The electrochemical sensing system was set up in a cylindrical quartz cell equipped with a standard three-electrode configuration and controlled by an electrochemical workstation (CHI 660C, CH Instruments Co., Ltd. USA). Both bare Ti02/Ti and functional GOD-Ti02/Ti nanotube array were used as the working electrodes with an effective reaction area of 2.0 cm2. A standard Hg/Hg2Cl2 saturated calomel electrode (SCE) was used as a reference electrode and Pt foil was used as a counter electrode. Standard calibration curve (responsive current... 

Electrochemical measurements were performed using a poten-tiostat, for example Autolab PGSTAT 12 electrochemical analysis system (Eco Chemie, The Netherlands) in connection with General Purpose Electrochemical System (GPES) software, or CH Instruments 660 Electrochemical Workstation (Austin, TX). The electrochemical set-up consisted of a SPE system is as shown in Fig. 4b. 

Electrical contact is completed using the copper disk connected to a copper wire into a cylindrical PVC sleeve (6 mm i.d., 8 mm o.d. and 160mm longitude) leading to the electrochemical workstation (see Fig. 2D).

A three-electrode system with a platinum working (H), a platinum auxiliary (K) and a reference saturated calomel electrode (I was placed in a U-type compartment (M) in an isothermal water bath (E). Two platinum wires jointing with the working and auxiliary electrodes, respectively, straight reached to electrolyte outside and connected to two copper wires which linked with the electrochemical workstation (B). The reference electrode was used to track the change in potential of electrode (H). A thermo-sensitive resistor (L)...

Every glass parts used in the experiments were immersed in Caro s acid, rinsed in deionized water, and cleaned by steam. The software controlling the electrochemical workstation was programmed in the National Instruments Lab VIEW environment. The software ean not only be used to define any kind of potential-controlling waveforms (provided that these can be defined either as a elosed-form expression, or as a combination of simple periodic functions), but it also allows to represent and evaluate the measured data in several ways. 

Thermal-oxidative degradation of polymer binders was investigated via derivatographic method on MOM device with the heating-up velocity of 3.2°/min. Electroconductive properties of nanocomposite samples (cross-section 0.2 cm, length 1 cm) were determined via impedance measurements (frequency 1000 Hz, amplitude 5 mv) on Electrochemical workstation CHI 660D.
