New Sampling Methods for the Extrinsic Multiple Time Scale Problem... [Pg.311]

The coarse-graining approach is commonly used for thermodynamic properties whereas the systematic or random sampling methods are appropriate for static structural properties such as the radial distribution function. [Pg.361]

Finally, analytical methods can be compared in terms of their need for equipment, the time required to complete an analysis, and the cost per sample. Methods relying on instrumentation are equipment-intensive and may require significant operator training. For example, the graphite furnace atomic absorption spectroscopic method for determining lead levels in water requires a significant capital investment in the instrument and an experienced operator to obtain reliable results. Other methods, such as titrimetry, require only simple equipment and reagents and can be learned quickly. [Pg.44]

A randomly collected sample makes no assumptions about the target population, making it the least biased approach to sampling. On the other hand, random sampling requires more time and expense than other sampling methods since a greater number of samples are needed to characterize the target population. [Pg.184]

The hnearity between M and makes the concept of absorbance so usehil that measurements made by sampling methods other than transmission are usually converted to a scale proportional to absorbance. The linearity between M and i is maintained only if the resolution of the spectrometer is adequate to eliminate contributions from wavelengths not absorbed by the species being measured. In addition, the apparent value of a is very dependent on resolution because a is 2l strong function of wavelength (30,31). [Pg.197]

By far the largest proportion of gas sampling operations in industry is carried out for environmental reasons and the sampling methods employed have been thoroughly researched and are well documented (5—12). The preparation, precautions and equipment requirements involved in the sampling of air pollution sources are appHcable to most other gaseous environments (see Airpollution control methods). [Pg.299]

Although mechanical sampling methods are to be the focus of attention, manual sampling methods are also employed for practical sample collecdion in commerce. Techniques of mechanical sampling should be emulated as closely as possible for best results with sampling by manual procedures. [Pg.1756]

Calculation of Sample Extraction Increments Sample quantities taken in an extraction increment are calculated in accord with the mechanical sampler employed. The following three examples illustrate calculations for three commonly used sampling methods. [Pg.1761]

Method or samphng, location, size and number of samples, method of sample analysis, and fraction of the batch removed for samphng all contribute to how well the samphng study reflects the actual conditions. [Pg.1763]

When the operating conditions are uniform and steady (there are no fluctuations in flow rate or in concentration of CO in the gas stream), the continuous sampling method can be used. A sampling probe is placed in the stack at any location, preferably near the center. The sample is extracted at a constant sampling rate. As the gas stream passes through the sampling apparatus, any moisture or carbon dioxide in the sample gas stream is removed. The CO concentration is then measured by a nondispersive infrared analyzer, which gives direct readouts of CO concentrations. [Pg.2201]

Figure 25-35 is a schematic of an assembled sampling apparatus used to determine CO concentrations by the continuous sampling method. [Pg.2201]

The measurements are also subjec t to systematic errors ranging from sensor position, sampling methods, and instrument degradation... [Pg.2547]

Samples will form iTudtiple phases. The laboratory secondary sampling methods must recognize the presence of vapor, liquid, and solid phases. Improper secondaiy sampling methods will result in distorted measurements. These limitations must be clearly communicated to the laboratoiy. [Pg.2559]

These potential sampling problems must be solved in advance of the unit test. The conclusions drawn from any unit test are strongly affected by the accuracy of the sampling methods and the resultant analyses. Methods should be discussed and practiced before the actual unit test. Analysts should use the trial measurements in prehm-inary plant-performance analysis to ensure that the results will be use-bil during the actual unit test. [Pg.2559]
