A skilled laboratory assistant can apply 20 samples in < 10 min. The scanning, however, is done more and more automatically. Janchen56) demonstrates, how much time is consumed by the various analysis steps and how much of this time is taken up by the laboratory assistant when sample application and measurement are performed automatically. When 33 samples are analyzed twice he gives a total analysis time of 148 min, of which 30 min are the assistant s time, that is 1 min for 1 sample. This does not include the time for sample preparation, as the latter is dependent on the type of sample. In general, sample preparation requires less time in thin-layer chromatography than in other kinds of chromatography. 

A detailed description of the biochemistry, chemistry and biology of natural colour pigments can be found in the book Natural Food Colorants. The book also covers the role of biotechnology in the production of colorants as well as safety aspects. Another book with the same title, Natural Food Colorants, assembles the manuscripts from a two-day Basic Symposium on Natural Colorants held in Chicago in July 1999. The book covers natural colorant chemistry, preparation, formulation, application and measurement as well as safety, regulatory and health considerations. ...

Because of their high Curie temperature ( 1070K) and thermal stability, Alnico materials are used in high-temperature applications and measuring instruments. They are also used in loudspeakers, but strong competition from cheaper hexagonal ferrites is decreasing their share of this market. 

Properly administered, choosing leading indicators, promoting their application, and measuring the quality of those endeavors is a good idea. 

Photothermal spectroscopy is a class of optical analysis methods that measures heat evolved as a consequence of light absorption in an irradiated sample. In conventional spectrometric methods information is obtained by measuring the intensities of light transmitted, reflected, or emitted by the sample. In photothermal spectrometry, spectroscopic information is obtained by measuring the heat accompanying non-radiative relaxation. Because of the universality of the photothermal effect (e.g., heat evolution accompanies essentially all optical absorption), photothermal spectroscopy has diverse applications in chemistry, physics, biology, and engineering. Some applications and measurements in the analysis of solids are reviewed here. 

A sensor is a device that responds to an external stimulus with a measurable response. In this chapter, we restrict our discussion to sensors that respond to chemical species, including oxygen and water vapor (humidity). There are many applications of chemical sensors, including monitoring gas-phase species for air quality and safety applications, and measuring pH or other ion concentrations in water samples. Sensors also find use in healthcare, forensic, security, and consumer product applications. 

This chapter describes the application and development of trace gas detection based on PTR-MS within life sciences. The chapter begins with a short overview about the ion chemistry that is used in these mass spectrometer systems to sensitively measure trace gases. The overview is followed by the experimental description of the system, including practical aspects such as how to perform a calibration or the use of natural isotopic ratios to gain some information about the identity of the detected compounds. The main part of the chapter deals with applications and measurements performed with PTR-MS to study processes inside plants, fruit, bacteria, and insects interactions between plants and pathogens and also as a tool for human health research. 

In real leaves, there will be lateral diffusion of CO2, and correlated closure may not occur among opposite stomata in the upper and lower epidermis. An exact equality of the fraction of closed stomata with the relative reduction of the rate of photosynthesis is therefore not to be expected nevertheless, discrepancies between measured rates of photosynthesis and computed values of Cj would appear. In the case of stomata responding proportionally, computed values of Cj will be applicable, and measured rates of photosynthesis represent working points on the saturation curve of COo assimilation. 

The great diversity of application, the size range of atmospheric aerosol particles, the physical and chemical concentration variations, and the variety of measurement principles available imply many different combinations of application and measurement methods and procedures. Therefore, this chapter is focused on the most important methods in use. The methods applied for atmospheric aerosol sampling include filters and cascade impactors which collect the aerosol particles onto a surface. The collected sample must therefore be evaluated for size and composition. Because accumulation mode aerosols (fine aerosol particles) contain a substantial fraction of liquid material at normal temperatures and humidities, these fine aerosol particles must be sized in situ without precipitation. In some extreme cases, such as in Los Angeles smog, the liquid content may be as high as 75% or 80% of the total mass (Ho et al., 1974). 

In accordance with the previous chapter the very application developnemt will be executed. That especially means that the application will be separated into two functional units which will function separately, and their cooperation will ensured by the proper transmission of data. The middle of the application is Bluesense Control, this part also manages the communication between the application and the wireless Bluetooth module BluesenseAD. It also ensures the transfer of data visualization. The relationship between parts of applications and measurement module is shown in Figure 1.
