7 The Analytical Problem
(22) Can an analytical problem result from a scientific or technical need? Give
some examples.
(23) Can an analytical problem be approached without a deep knowledge of the
information needs raised by the social-economic problem?
(24) Comment extensively on Example 1 in Box 7.4 (approaching an analytical
problem).
(25) Comment extensively on the analytical problem derived from light foods
(Box 7.5).
(26) In what types of analytical problem will the use of sensors be appropriate?
Why? Give some examples.
(27) Comment extensively on Example 2 in Box 7.4 (approaching an analytical
problem).
(28) Comment on the factors that influence the decision involved in the third
step of the analytical problem-solving process and on their mutual
relationships. Use a specific example.
(29) When will it be justified to use a hyphenated instrumental technique such
as GC-MS, LC-MS or FTIR-MS?
(30) Comment extensively on Example 3 in Box 7.4 (approaching an analytical
problem).
(31) Explain the constraints that may arise from the client's imposing a
maximum cost per analysis.
(32) Give two examples of analytical problems involving the determination of a
single or many analytes.
(33) In what way do relationships among analytical properties influence the
manner an analytical problem is to be approached?
(34) Why do the basic properties sensitivity and selectivity of a CMP have a
critical influence on the third step of the analytical problem-solving
process?
(35) The first two steps of the analytical problem-solving process involve specifying information. What is the difference between them? In what way are
they related?
(36) Give two examples of analytical problems where expeditiousness is the key
analytical property.
(37) Comment extensively on the analytical problem faced by a vegetable and
fruit growing industry as a result of its produce being contaminated with
pesticides.
(38) What are the references to be used to validate the results in the fourth step
of the analytical problem-solving process?
(39) Give some examples where the analytical information delivered is inadequate to solve the social-economic problem faced.
(40) Why is the analytical problem not properly solved when more analytical
information than is required is supplied?
(41) Explain why the need for highly accurate, minimally uncertain information
influences the choice of CMP.
(42) With the aid of an example, explain when a corrective action (fifth step of
the analytical-problem solving process) must be implemented.
