Analysis and Monitoring

The mass spectrometer sampling capillary or the dispersive infra-red analyzers used for continuous analysis and monitoring of the gas phase composition are situated between the reactor and the sampling valve, as close to the reactor as possible, in order to avoid any delay in the recording of changes in the composition of reactants or products. This delay should be taken into account when plotting simultaneously the time dependence of catalyst potential or current and gas phase concentration of the reactants or products.

Two of the most widely used and detected UV filters in the environment and WWTPs are BP3 and 4-MBC. Thus, they were the selected compounds to study individually their degradation by fungi [44, 49]. Studies with BP1, not only a BP3 metabolite but also an industrial UV filter (but its use in cosmetics is not allowed) itself have also been performed. Studies in liquid media allow a better analysis and monitoring of many parameters, both the contaminant concentration and the fungal metabolic state such as glucose consumption and enzyme production. In these studies, the degradation process was performed with the fungus in form of pellets. 

Lacking analysis and monitoring data of processes in the natural system in some circumstances there are no, or not enough, monitoring data collated, for instance, due to a long-term duration of a number of processes. 

The analytical strategy for a continuous process is necessarily predominantly online, as summarised in Figure 8.3. However, the correlations between continuous process development and online analysis on the one hand and batch process development and off-line analysis on the other are not simple. For example, many aspects of batch process development would benefit from the availability of online analysis and monitoring. Similarly, some of the early development stages of a continuous process will utilise data from batch (i.e. non-continuous) experiments.

The number of different total (summary) parameters that can be used in environmental analysis and monitoring is very large. For illustration, Table 10.36 lists examples of various parameters used by researchers to characterize gaseous, liquid, and solid samples, published between 1978 and 2000.

It should be noted that task granularity can change depending on NUMA performance characteristics of different MPP systems. In essence, these three software/hardware attributes (NUMA, granularity, and load balance) are interrelated and must be optimized for each application and on each MPP system. Optimization techniques require performance analysis and monitoring tools that allow the programmer to determine the appropriate portion(s) of the application that must be tuned. 

This book series will ensure a wide coverage of issues related to water quality measurements, including the topics of the above mentioned courses and the outcome of recent scientific advances. In addition, other aspects related to quality control tools (e.g. certified reference materials for the quality control of water analysis) and monitoring of various types of waters (river, wastewater, groundwater) will also be considered. 

Analytical usefulness of immobilized bioluminescent assays depends on properties of their immobilized enzymes. The most popular application of immobilized bioluminescent systems is for analysis and monitoring of chemical and biochemical analytes and environmental pollutants. The wide range of analytes measured and monitored by immobilized bioluminescent systems has been reviewed. Stability, sensitivity, precision, and effects of interfering substances and the microenvironment are also discussed. 

Quality assurance is about getting the correct result. In environmental analysis and monitoring, this involves several steps, including sample collection, treatment and storage, followed by laboratory analysis. A complete environmental protocol is shown in Figure 2.1. It is likely that the variation in the final measurement is more influenced by the work external to the analytical laboratory than that within the laboratory. Two important terms in quality assurance are accuracy and precision. 

Article 8, paragraph 3 of the WFD requires that technical specifications and standardised methods for analysis and monitoring of water status be laid down in accordance with the procedure given in Article 21. Moreover, Annex V. 1.3.6 of the WFD states that the standards for monitoring of quality elements for physico-chemical parameters shall be any relevant CEN/ISO standards or such other national or international standards, which will ensure the provision of data of an equivalent scientific quality and comparability.
