Monitoring methods

There are two different possibilities for studying a reaction using API methods, namely off-line and on-line screenings.

This monitoring method should make it possible to decide wether to continue with the pressurization of the vessel or to stop it, based on real-time and reliable detection and location of any potentially hazardous defect which is evolving.

Biosensors (qv) and DNA probes ate relatively new to the field of diagnostic reagents. Additionally, a neat-infrared (nit) monitoring method (see Infrared TECHNOLOGY AND RAMAN SPECTROSCOPY), a teagenfless, noninvasive system, is under investigation. However, prospects for a nit detection method for glucose and other analytes ate uncertain. 

Some assumptions must be made to do this, but these assumptions are no different from those made in the laboratory. Recent experience involving in-plant usage of EIS has shown that this technique can be used effec tively as a monitoring method and has lead to development of several commercial systems. 

Other measurements important to visual air quality are pollutant related, i.e., the size distribution, mass concentration, and number concentration of airborne particles and their chemical composition. From the size distribution, the Mie theory of light scattering can be used to calculate the scattering coefficient (20). Table 14-2 summarizes the different types of visual monitoring methods (21).

There is also a framework for the use of biological monitoring in the UK. A biological monitoring guidance value has been set where it is likely to be of practical value, suitable monitoring methods exist and sufficient data are available. 

In summary, these exploratory data suggest that the chromatographic method used could be a valuable tool for study of this polymerization reaction. Reasonable data were obtained for amount and composition of the copolymer. Formation of graft polymer and/or nitrile rich polymer was detected. More detailed chromatographic study of this batch polymerization could lead to a practical on-line monitoring method... 

Electrochemical On-Line Corrosion Monitoring On-line corrosion monitoring is used to evaluate the status of equipment and piping in chemical process industries (CPI) plants. These monitoring methods are based on electrochemical techniques. To use on-line monitoring effectively, the engineer needs to understand the underlying electrochemical test methods to be employed. This section covers many of these test methods and their applications as well as a review of potential problems encountered with such test instruments and how to overcome or avoid these difficulties. 

The evaluation of all NADA analytical methods was previously conducted exclusively by the CVM. Since 1995, the CVM has offered sponsors of NADA residue methods the option of conducting the method trial through a Sponsor Monitored Method Trial (SMMT) process. The SMMT is conducted according to CVM specifications with CVM oversight. The resultant performance data must be reviewed and judged acceptable by CVM before the method is approved. 

Finally, the method must be shown to be practical for use as a routine monitoring method. The method must use commercially available reagents, standards, and equipment. The method must not be too complex or poorly described such that an experienced analytical chemist could not understand or perform the method. Steps of the procedure that are critical should be highlighted in the method so that they can be appropriately controlled. The method must be short enough so that it can be used...
