Interactive TrainingTM
Atomic Absorption Spectrometry
This recently upgraded and expanded training package, written by an experienced
practical atomic spectroscopist, contains a wealth of information about
all aspects of AAS. It gives comprehensive descriptions, with animated,
interactive demonstrations, of the principles, instrumentation and practical
applications of Atomic Absorption Spectrometry, with self-test multiple
choice questions on each module.
The four modules included are as follows:
Atomic Theory
-
Introduction to spectroscopy (electromagnetic radiation, atomic energy
levels, electron configuration, term diagrams, line and band spectra).
-
Line intensity (Boltzmann and Saha distributions, temperature effects).
-
Line shapes (the Uncertainty principle, Doppler and pressure broadening).
AAS Instrumentation
-
Radiation sources (hollow cathode lamps, including sputtering and self
absorption).
-
Flame atomization (flame profile, fuel/oxidant ratio, flame chemistry,
pre-mix burner, sample nebulization).
-
Electrothermal atomization (temperature programming, interferences, autosamplers,
and background correction).
-
Single and double beam instruments, monochromators, detectors.
Analysis using AAS
-
Sample preparation, (ashing, fusion, solubilization, hydride generation,
mercury cold vapour technique).
-
Spectral interferences, (ionisation, chemical, electrothermal atomizer,
matrix modification).
-
Quantitative determination using Standard Additions.
-
Example 1 - measurement of Mg in orange juice using the flame, (preparation
of aqueous calibration standards, setting up the instrument, standard additions
method).
-
Example 2 - measurement of Al in drinking water using the electrothermal
atomizer, (preparation of aqueous calibration standards, setting up the
instrument, standard additions method).
Questions & Answers
-
Users are tested on their knowledge of the material in the package using
multiple choice questions.
Interactive AAS is one of a range of training packages for analytical chemistry:
also available are Interactive GC, Adv.GC,
HPLC, ICP & MS.
They are suitable for both college students and laboratory staff, giving
sufficient emphasis to both theory and practice. Network versions are available.
There is now a wealth of research demonstrating the advantages of computer-based
training as compared to traditional methods: increased understanding and
retention, shorter training time, constant availability, flexibility of
use and considerable cost savings. Training is no longer dependent upon
having access to instruments, and can be tailored to individual requirements.
Trainees can watch the animation demonstrating the working of the instrument;
adjust parameters to see their effect; pursue their own lines of inquiry;
and return to areas of uncertainty. The software has a free flow, open-ended
structure which enables the user to browse freely through its pages, or
to follow the programmed order. Thus a useful session may last 10 minutes
or several hours.
Requires Windows 3.1, 95, 98 or NT
