Advantages and Disadvantages of Each Technique

The aim of this chapter is, therefore, to introduce briefly the most common quantitative atomic techniques based on both optical and mass spectrometric detection. The main emphasis will be given to conceptual explanations in order to stress the advantages and disadvantages of each technique, the increase in the complexity of the data they generate and how this can be addressed. References to chemometric tools presented in the following chapters will be given. 

We have shown some of the ways that mixed associations could be analyzed by light scattering, Archibald, or sedimentation equilibrium experiments. It might be appropriate at this point to make a comparison of some advantages and disadvantages of each technique. 

Compare three different ECP approaches with ECMP. What are the planarization mechanism, advantages, and disadvantages of each technique ... 

In order to understand the potential utility of polymeric materials, the first part of this chapter is devoted to fundamental and background aspects of the different types of polymers. A brief description is given of the synthesis of reactive polymers either by polymerization or by chanical modification techniques as well as an explanation of potential advantages and disadvantages of each technique. 

Surface tensions of poljuneric fluids or melts may be measured by a variety of direct techniques, with those based upon analysis of the shape of axisymmetric fluid drop profiles (3,72) the most versatile and popular. Discussions of the relative advantages and disadvantages of each technique are presented in Reference 3. Several drop geometries are possible as shown in Figure 18. The shape of these drops is governed by the Bashforth-Adams equation... 

The latter three methods generally produce a single deposit per dispensing step. The first two methods enable the application of the material at multiple sites in a single step. Of course, the five techniqnes do not perform equally well for the three materials. This section discusses the advantages and disadvantages of each technique. 

Many techniques can be used to solve multivariable optimizations. Unfortunately, there is no single best method that applies to every type ofresponse surface. Therefore, I will give a number of different procedures, with the advantages and disadvantages of each one. The reader will then have to decide which one(s) he wishes to use. 

Many inhalation exposure techniques, such as the whole-body, nose-only, mouth-only, or head-only technique (Drew and Laskin, 1973 MacFarland, 1976 Leong et al., 1981 Phalen, 1984 Nelson, 1980), the intranasal exposure technique (Elliott and DeYoung, 1970 Smith et ah, 1981), the endotracheal nebulization technique (Leong et ah, 1985, 1988 Schreck et ah, 1986), and the body plethysmographic techniques (Alarie, 1966 Thome and Karol, 1989), have been developed for inhalation toxicity studies. Table 10.2 provides a summary of the advantages and disadvantages of each of the major inhalation exposure methodologies. 

Compare the techniques of lyophilization and centrifugal vacuum concentration. Give advantages and disadvantages of each. 

According to the above, the electrochemical response in the different differential pulse techniques can be very different, and it is worth analyzing the advantages and disadvantages of each method. Regarding the double pulse methods, in normal mode, DNDPV, this has the inconvenience of presenting asymmetrical peaks that can hinder the experimental determination of the peak current. In addition, the peak... 

The objectives of this chapter are to discuss kinetic methods that are available for studying reactions on soil constituents, how one can analyze the data from these techniques, and the advantages and disadvantages of each method. 

Once finite-difference equations are obtained for a conduction problem, what methods are available to effect a solution What are the advantages and disadvantages of each method, and when would each technique be applied ... 

In the following sections, the advantages and disadvantages of each method will be illustrated by pertinent examples. The various techniques for removing hydroxy or amino are arranged according to the basic mechanistic process involved in the key step. 

At this point, the sample is analyzed by gas chromatography (GC), the analytical method of choice for volatile halogenated hydrocarbons. Information on the analysis of these samples by GC is presented in Section 6.2, with a discussion of the advantages and disadvantages of each method. The technique of Antoine et al. (1986) showed a 5% variance on a series of 2 ppb spiked samples, and the analysis had a linear response ranging from 0.5 to 50 ppb. Although infra-red spectrometry has less sensitivity than electron capture detectors (ECD), Hall electroconductivity detectors (HECD), and mass spectrometrlc detectors (MS), it has been used to quantify the levels of... 

In summary, this chapter presents the entire breadth of LM technology with the intention of furthering research and industrial applications. The various types of liquid membrane configurations are surveyed and the advantages and disadvantages of each type are described. The tutorial section of this chapter also discusses typical experimental techniques and a survey of theoretical approaches.
