4.3.3.4 Inductively Coupled Plasma Techniques Atomic absorption spectrometry has a number of disadvantages for use in analysing large numbers of samples of varying elemental composition and concentration. What are the two major problems in the use of AAS for such samples? Answer AAS can only determine one element at any one time. The technique becomes slow and tedious for multi-element analysis. The variations in concentrations of the samples can be problematic as the linear range of AAS is very limited.<\/p>\n

The development of the inductively coupled plasma (ICP) techniques for water analysis can be seen as an attempt to overcome these problems. At the same time, they maintain the advantages of graphite furnace AAS of being suf\ufb01ciently sensi- tive not to require a preconcentration stage and also in not using \ufb02ammable or explosive gases. This permits unattended, 24 hour, operation. In both methods, the sample is atomized in a plasma \ufb02ame at 6000\u201310 000 K (Figure 4.18).<\/p>\n

This is generated by a \ufb02owing stream of argon which is ionized by an applied radiofre- quency (RF) \ufb01eld. Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). With this technique, the emission spectrum is monitored. Simultaneous ICP- OES can determine 60 or more elements at once by monitoring at pre-set wavelengths.<\/p>\n

This includes halogens and some other non-metals and metalloids, as well as metals. Sequential spectrometers, which are more common for water analysis, restrict themselves to a smaller number of elements, determined by the requirements of the analysis, measured in succession by rapid changes in the detection wavelength. The total analysis time is still fast, typically 5 s per element. A further advantage of ICP-OES is its wide dynamic range (approximately 105), which means that trace metals can be measured simultaneously with higher-concentration species.<\/p>\n

In common with other emission techniques, there is the problem of spectral overlap from different elements, as an element will produce many more lines in its emission spectrum than in its corresponding absorption spectrum. The choice of the analytical wavelength is based on freedom from interference as well as sensitivity.<\/p>\n
