In summary, recycle results in increased throughput, reduced separation time, lower solvent consumption, and complete recovery of the compounds (if desired) in the preparation mode. Chapter 10 (Experiment 3) contains an experiment that illustrates the basic experimental techniques of accomplishing recycle chromatography. 

In this chapter we focus on a few selective new VCD applications reported in the last 5 years, along with a brief review of the basic experimental techniques and theoretical methods. The remainder of this chapter is organized as follows. In the next section, we will present the VCD experimental technique with a short review of VCD instrumentation and some recent developments, and describe the usual procedure to obtain VA and VCD measurements in solution and in thin film states. In Sect. 3 the associated VCD computational simulations will be illustrated. This includes a brief historical overview of the theory development, and some basics related to VCD calculations, as well as the typical procedure of carrying out VCD simulations. The main part of this chapter deals with the diverse applications of VCD spectroscopy, focusing on the new developments in the last 5 years. Since there are a large number of publications which are dedicated to AC determinations of many interesting and important chiral molecules, a comprehensive review of all... 

This chapter is intended to introduce the reader to the basic experimental techniques used in low-energy positron studies of solids, liquids and gases, as well as in fundamental studies involving the positron itself. They are not an exhaustive review of research work in the field—in addition to this work there are a number of books to which reference can be made (e.g., [1-5]) and so specific pieces of research will only be referred to when they provide an illustration of a particular technique or device. 

The basic experimental techniques of structure determination, i.e. microwave spectroscopy (MW) and electron diffraction (ED) for the gas phase and X-ray diffraction (XD) for crystals, as well as the physical meaning of parameters obtained (r, r, r, etc.) are... 

Many refinements of the basic experimental technique have been reviewed by Alexander and by Gaines , some are briefly mentioned below. In certain experiments, it may be necessary to make measurements of surface pressure on a substrate whose surface tension is changing. 

Consider now the basic experimental techniques for studying the kinetics of liquid-phase reactions. 

The basic experimental techniques for studying reaction dynamics involve either (1) instantaneous rate determinations at various known concentrations of reactants, usually when the reaction is just begun, or (2) determining the relationship between concentration and time.

In the rapidly developing field of cold molecules, Feshbach molecules play a particular role as the link to research on ultracold quantum matter. In this chapter, we have presented the basic experimental techniques and discussed some major developments in the field. In this final Section, we briefly point to some other recent developments not discussed so far, adding further interesting aspects to our overview of the research field. 

The basic experimental technique has been described in detail by Madix (ref. [5] and references therein), As normally applied it requires the production of a well-collimated, high intensity amplitude modulated molecular beam. This... 

In this chapter we introduce the basic experimental techniques and associated glassware and apparatus that are commonly used in the organic chemistry laboratory. In some Instances, only the practical aspects of a particular technique are discussed in this chapter, and the theoretical principles underlying it are presented in later chapters. 

Abstract The physical principles and basic experimental techniques of impedance spectroscopy, i. e. static or frequency dependent dielectric permittivity measurements of sorbent/sorbate systems are given. These measurements can be used to characterize the state of a sorbent material in industrial adsorption processes. Combined with either manometric or gravimetric measurements of adsorption equilibria leading to calibration curves, permittivity measurements also allow fairly simple and quick measurements of gas adsorption equilibria. Kinetic processes and catalytic reactions inside a sorbent/sorbate system also can be observed. Pros and cons of dielectric measurements are discussed. List of Symbols. References.

When the effect of temperature on the rate of electrode reactions at a constant electrical state of the WE is determined, there are two basic experimental techniques which may be distinguished with respect to the temperature regime used to control the temperature of the electrodes in the WE-RE cell (i) the technique of isothermal cells, in which both the WE and the RE are kept at a common ten erature throughout the measurements, and (ii) the technique of nonisothermal cells, in which the RE is kept at an arbitrarily selected constant temperature during all...
