In classical examples of kinetics, such as the hydrolysis of cane sugar by acids in water solution, the reaction takes hours to approach completion. Therefore Whilhelmy (1850) could study it successfially one and a half centuries ago. Gone are those days. What is left to study now are the fast and strongly exothermic or endothermic reactions. These frequently require pressure equipment, some products are toxic, and some conditions are explosive, so the problems to be solved will be more difficult. All of them require better experimental equipment and techniques. 

Schampel and Steen (1975) describe experimental equipment and tests carried out at the Physikalisch-Technische Bundesanstalt (PTB) in Germany on high velocity vent valves. Also, conditions for a sufficient air entrainment and dilution of the vented flammable vapors are discussed. 

Therefore, we see that the development of EEP semiconductor detectors is a challenge that expects knowing of diverse experimental equipment, and, what is more, carrying out some particular investigations. The experimental difficulties, however, are compensated for by the ad-... 

Chemical engineers should be aware of the existence of relaxation techniques for studies of very fast reactions. However, since relaxation time measurements call for sophisticated experimental equipment and techniques, they are seldom made outside of basic research laboratories. 

Structure determination of unsaturated compounds can be supplemented by thermal desorption (TD) and electron energy loss (EEL) spectroscopies. The two methods use the chemisorption of cis and tram enes or dienes to the Pt(lll) surface over a range of temperatures11. The experimental equipment and procedures described12 show these methods to be employed for dienes such as 1,3-butadiene. At veiy low temperature the diene is adsorbed on Pt(l 11) and the thermal desorption is followed by increasing the temperature. 

The main parameters for the experimental equipment and system design are listed below ... 

The appropriate tools such as software, experimental equipment, and instruments for executing the task should be identified. The activities to meet the objective such as computer simulation, modeling and experimentation are defined. To meet the project deadline, it is also necessary to estimate the time needed to complete the tasks. Proper allocation of human and monetary resources to perform the activities is also essential [3].
