6 Quantitative Aspects of Analytical Chemistry
I Seminar 6.1
Calculating the Results in Quantitative Analysis
• Learning objective
To describe the third step of CMPs intended to quantify the amount or concentration of analyte in a sample the mass (or volume) of which will have to
be considered in expressing the quantitative result.
• Literature
Analytical Chemistry handbooks and textbooks describing CMPs for quantitative purposes. Select CMPs based on calculable (e.g. gravimetries, titrimetries) and relative methods.
• General procedure
(1) Compile and justify the formulae used by the different calculable
methods.
(2) Compile and justify the procedures used to process the method calibration data provided by the different relative methods.
(3) Select quantitation methods, preferably typical of each category. For each
method:
(a) identify standards,
(b) describe the calibration processes,
(c) describe the procedure used to calculate the quantitative result, and
(d) solve numerical problems from simulated data for the analytical
chemical standards and measurements.
(4) Describe three or four quantitation procedures of different types and
discuss their similarities and differences in terms of the way the output is
obtained.
Seminar 6.2
Forms of Expressing Quantitative Results
• Learning objective
To become acquainted with the different ways , efexpressing quantitative analytical results and their mutual relationships.
• Materials
Use the information given in this chapter '( especially in Boxes 6.1-6.4).
• Procedure
(a) Systematically describe the different ways of expressing a quantitative
result.
(b) Establish the principal links betwee, n the different forms of expression:
(1) Absolute H relative.
(2) Mass/volume H mass/mass.
