Q2. What are the main applications of the process?
several processes recur in a variety of applications: signal averaging, digital filtering, direct digital control, and the display of results.
Q3. What is the main reason for the introduction of computers in chemical analysis?
Increasing labour costs and decreasing costs of computers and secondary memory now favour the introduction of computers in classical chemical analysis.
Q4. What are the main reasons for automation in the laboratory?
Applications of on-line computers in the laboratory with emphasis on reduction of human labour mostly concern data acquisition, report generation and simple pre-programmed routine control actions.
Q5. What is the advantage of digital converters?
Modern high-speed digital hardware enables on-line computers equipped with analog-to-digital converters (ADC) and digital-to-analog converters (DAC) to perform these tasks.
Q6. What is the first category of methods?
The first category includes the multiparametric curve-fitting methods; these methods require a theoretical equation relating the measurement variables to a number of parameters that describe the experiment.
Q7. What is the first application of the multiparametric curve-fitting methods in classical analysis?
The first application of these pattern recognition methods in classical analysis was reported by Sybrandt and Perone 1251; this concerned the deconvolution of severely overlapping peaks obtained by polarography at a hanging mercury drop electrode.
Q8. What is the way to learn the LSI?
It is important to note that although the learning methods require lengthy calculations in training, the final recognition calculations are simple and very fast.
Q9. What is the way to integrate the knowledge from the three disciplines?
University courses in analytical chemistry, traditionally of a multidisciplinary character, are best suited to accomplish this integration_
Q10. What is the main reason for the need for specialized equipment?
there will remain a need for specialized equipment, especially for monitors in industrial processes and environmental control.
Q11. What is the way to improve the accuracy of the analysis?
Also pattern recognition types of data processing should find increased application, especially in cases where the relation between the information wanted and the data measured is complex.
Q12. What are the known control problems for electroanalytical methods?
Probably the best known are the control of the electrode potential (or sometimes current) in various electroanalytical methods, and the control of titrant addition (or generation for coulometric titrations) in set-point titrations.
