Computer assisted-method development tool

Computer-assisted method development has received a great deal of attention from management within the pharmaceutical industry, mainly from the perspective of cost savings associated with faster and more efficient development. Adoption and incorporation of the tools in day-to-day workflows has been relatively hmited due in part to a reluctance of chromatographers to believe that computers can replace the intuition of the expert chromatogra-pher. With the present state-of-the-art, there is little question that computers can play a role in efficient method development. However, it must be accepted that computers are a supplement to, rather than a replacement for, the knowledge of the method development chromatographer. 

The highly precise conduction of parallelized catalyst synthesis and testing of small amounts of material in combination with computer assisted methods for designed experiments, including the development of database tools, and modelling tools represents one of the biggest growth areas in catalysis. 

The new Chapter 10 has been added to cover the use of computer-assisted methods used in design. It also includes the use of the computers in manufacturing since data from the product design can be used to generate the tooling required for production. The new chapter reflects the widespread and increasing use of the computer in the development of new products—especially in the plastics field. 

One of the primary questions that have plagued method development chro-matographers is, Where do I start This question applies equally to any school of thought, whether the chromatographer uses no optimization tools, uses computer-assisted optimization, or even uses on-line optimization. In any of these cases, the chromatographer must choose a proper starting point. 

The development of today s pulse calorimeters started more than 35 years ago, when scientists used exploding wires to generate dense plasmas, or as bright light sources, and began to realized the potential of this method for measurement of liquid-state properties. Ever since, improvements, such as better and more accurate electronics and instrumentation, or computer assisted data recording and evaluation, have helped to constantly improve and establish pulse calorimetry as a tool for temperatures inaccessible to more common techniques. The fundamental principles and relations for pulse calorimetry have been presented and discussed, as well as demonstrated by data for pure iridium in the solid and liquid states. 

With growing data banks of rate constants of elementary steps, it appears that kinetics assisted design of new catalytic processes will accelerate the development of improved catalytic processes. With powerful computational methods of thermodynamic and kinetic parameters, microkinetic analysis has emerged as a mature method to describe existing processes in combustion, polymerization, homogeneous and heterogeneous catalysis. In catalysis, the method is now poised to become one of the tools of catalyst development with the help of surface science, organometallic chemistry, materials science, com-...
