It is reasonable to question whether the distribution of the estimates of a drug concentration in a blood specimen might be approximated by the normal distribution. Table 1 presents the results of repeated analyses of a specimen of interference-free plasma spiked to contain a known amount of drug. These data are taken from a comparative bioavailability study in which single doses of an unmarketed generic product and the marketed brand product of a drug were administered on separate occasions to healthy males. The values presented are the first of duplicate determinations of a quality control (QC) specimen that was included with each batch of subject specimens. This was done to verify that the in-process accuracy and precision of the assay method were consistent with the values observed during the assay validation. 

While the above approach works very well at temperatures below 100 °C, it is difficult to apply the IUPAC recommendations at temperatures above 100 °C when a high-temperature system should be pressurized. Definitely, at temperatures below 300 °C the HECC represented by (25) can be employed for pH measurements in the solutions where the half-reaction of the Pt(H2) electrode is a reversible process. Accuracy of the measurements could be 0.01 pH units and is mainly limited from estimating the diffusion potential in Eq. (26). 

A wide variety of sensors are available for measuring process variables. Choosing the proper sensor for a particular application depends on the controlled variable that is to be sensed, the properties of the process, accuracy and repeatability requirements, and costs, both initial and maintenance. The following is a coverage of the most commonly used sensors in the CPI that are used for feedback control. 

The inline dilution system shall allow the preparation of buffers with an inline dilution factor ranging from 1 to 10. This factor determines the ratio of water to concentrated buffer. Larger ratios are of course feasible, but there is a trade-off between the process accuracy and flexibility to be taken into account. The systems shall cope as well with process disturbances and shall be robust again changing process conditions (such as pressure drop in a chromatography column or a sudden change in pressure or flow rate in the primary water supply). The robustness of such systems is crucial since pharmaceutical processes are validated to run in certain predefined limits. Any deviations to such limits will lead to additional investigation costs that could have severe consequences, in the extreme situation the withdrawal of the produced product. 

The examples of SERS and SERRS measurements in the biochemical field reviewed in this article were selected to illustrate the sensitivity, molecular specificity of adsorption process, accuracy, ease of sample preparation, and significant manifold apphcations of Raman analysis by SERS and SERRS for biomolecules in the adsorbed state.

The cognitive capacities of humans in the system (e.g., knowledge, learning ability, processing speed, and processing accuracy). 

Spectrochemical analysis is a comparison method. The precision of the analysis depends on the care taken in processing the sample and in all steps of the analytical process. Accuracy depends on the care exercised in developing the comparison standards. 

Statistical Process Control (SPC) Use of statistical data from the ongoing evaluation of the output of a process to ensure process accuracy and precision. 

In summary, the utility of micro-SERS spectroscopy for the evaluation of potential-dependent interfacial com-petititve and displacement reactions at chargwl surface has been demonstrated. The data obtained allow the determination of the chemical identity, structure, orientation, competitive and displacement adsorption of cationic surfactants and nitrophenol in the first adsorption layer. The examples of these measurements in the field of surfactants and organic pollutants reviewed in this article were selected to illustrate the sensitivity, molecular specificity of adsorption processes, accuracy, ease of substrate preparation, and manifold applications of Raman analysis. The spatial resolution of the laser microprobe, coupled with the 10 enhancement of the Raman cross-section, means that picogram quantities of material localized to pm-sized surfaces areas can be detected and identified by SERS vibrational spectroscopy.
