Secondly‚ Switch on the pH meter and place the electrodes into the pH 7.0 buffer solution then correct the pH meter indication and note down the reading after the beep sound comes. Wash down the electrodes with the distilled water using squeeze bottle into an empty beaker and wipe with soft tissue paper

have since been applied for the detection of disease and abnormalities in the GI tract where restricted access prevents the use of traditional endoscopy. Most radio telemetry capsules utilize laboratory type sensors such as glass pH electrodes‚ resistance thermometers‚ or moving inductive coils as pressure transducers. The relatively large size of these sensors limits the functional complexity of the pill for a given size of capsule. Adapting existing semiconductor fabrication technologies

Identification and Production of Materials ================================ Ethene‚ Polymers and Ethanol ================================ Catalytic Cracking Oil refineries need to balance their outputs of various products (petrol‚ diesel‚ fuel oil‚ etc.) to match the demands of the marketplace. Catalytic cracking is the process in which high molecular weight (high boiling point) fractions from crude oil are broken into lower molecular weight (lower boiling point) substances in order to increase

selective electrode used was made up of a silver / silver chloride reference electrode and a glass electrode. The pH of the electrochemical cell is determined by monitoring the electrical potential difference between the half-cells. The glass electrode is an ion selective electrode (ISE)‚ which only responds to the hydronium ion concentration / activity in a solution under a large range of conditions. In this experiment‚ we are measuring the fluoride ion concentration‚ which means our electrode responds

A salt bridge is used to connect the 2 electrolytes in order to enable the transfer of ions. Circuit is connected from electrode to electrode for mobile electrons to pass through. A galvanometer is always used to detect the electron flow of voltaic cell. The deflection of galvanometer indicates the electron flow of circuit. Electrolyte that has visible color change is always selected

After months of research and experiments‚ I have concluded my discovery of space worm touch receptors is definite. Regardless of the type‚ sensory receptors are influenced by physical actions and various stimulus. My research and experiments show that space worm touch receptors are no different. Stimulus is a change discernible by the body (Sherwood 2004) or in my case‚ a space worm. Certain receptors like touch receptors respond to stimulus weakly or strongly when involved with a different stimulus

biological recognition element to an electrode transducer. The purpose of the transducer is to convert the biological recognition event into a useful electrical signal. Amperometric and potentiometric transducers are most commonly used in conjunction with electrochemical biosensors. In potentiometric devices‚ the analytical information is obtained by converting the biorecognition process into a potential signal in connection to the use of ion selective electrodes (ISE). Amperometric biosensors operate
