Installation instrument

Instrumentation Calibration may be required for the instruments installed in the field. This is typically the job of an instrument mechanic. Orifice plates should be inspected for physical condition and suitabihty. Where necessary, they should be replaced. Pressure and flow instruments should be zeroed. A prehminary material balance developed as part of the prehminary test will assist in identifying flow meters that provide erroneous measurements and indicating missing flow-measurement points. 

Estabhsh the observed problem is real by hypothesizing potential problems with instruments and instrument installations. 

When groundwater contaminant plumes are suspected of having significant depth as well as lateral distribution, a three-dimensional array of monitoring points is needed to identify and characterize such plumes. Thus, groundwater data must be obtained from a number of different locations and from a number of different depths at each location. As a result, either a large number of drillholes are required, each with separate instrumentation installed, or instruments must be combined and installed at multiple levels in each of a smaller number of drillholes. 

For the pharmaceutical scientist, understanding the theory and application of the equipment is usually not sufficient there is the matter of compliance. The qualification of CE is similar to that of other instruments. Installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) apply in much the same way as high-performance liquid chromatography (HPEC). This chapter details the different parts of the modern CE instrument, equipment-related issues and troubleshooting, instrument qualification, and the future of the CE instrument. 

The terms instrument qualification and instrument validation are sometimes used indiscriminately. In this chapter, the term qualification refers to the site preparation and the testing employed to demonstrate that the instrument is properly installed in a suitable environment and the performance meets the predetermined specifications for its intended use. Qualification is a part of the whole validation life cycle. Validation refers to the process to provide assurance that the instrument is suitable for the intended application throughout the lifetime of the instrument. Installation qualification (IQ), operation qualification (OQ), and performance qualification (PQ) are performed to provide evidence that the user requirement specifications (URSs), functional requirement specifications (FRSs), and design qualification (DQs) have been met. The sequence of requirements setting and qualification events as well as the relationships between IQ, OQ, PQ and URS, FRS, and DQ are generally illustrated by the V diagram shown in Figure 2. Installation qualification demonstrates the fulfillment of the DQ. Similarly, OQ demonstrates the fulfillment of the functional requirements and PQ demonstrates the fulfillment of the user requirements. 

The DuPont Sabine River Works had reported between 35,000 and 40,000 instrument installations and more than 5,000 safety interlocks and alarms in 1988. The interlocks and alarms are divided into two classifications the operator aid is used to alert the operator of a nonhazardous abnormal condition that might otherwise be undetected the safety interlock or alarm refers to any equipment whose proper functioning is essential to prevent or signal hazardous process conditions that may threaten personnel or equipment.

Some people feel that columns cost too much and, therefore, purchase the lowest-price column. This is one strategy for choosing the best column. However, when the nature of a column in a chromatographic system is considered, it makes sense that there should be little to no price sensitivity in the user. For instance, if an instrument sells for 20,000, a typical column sells for 300. Therefore, a column is only 300/ 20,000, or 1.5% of the cost of an instrument installation. This is a minor part even if repeat buying is calculated. Second, keep in mind that without the column performance the entire instrument is worth precisely zero. Third, it is very hard to evaluate how a column will perform without prior experience with it—there is no easy believability to competitive claims that one C 8 column will work as well as, or even the same as, another. In essence, a column is nothing more and nothing less than a user s attempt to solve an analytical problem. Users should not be sensitive to price, they should be concerned with time, effort, and repeatability. Therefore, most individuals should gladly pay for these benefits, because the best column does your separation. 

The construction documentation package comprises the instrument installation specification, drawings, and documentation listed in Appendix 23E, Instrument Installation Specification. During this phase and thereafter, it is important that the drawing register for the manufacturing process is maintained on-site and that only the latest revisions of drawings are used.

Many manufacturers have large data banks using, for example, sieve analysis and they need to continue generating data in the same form. To cater for this need, some manufacturers of MALLS instruments install a conversion program, so that the instruments provide data that can be compared with historical data. However, Austin [190] compared sieve analyses with Sedigraph and Microtrac data and found that the conversion... 

There are two large electrical contractors well qualified to handle the job. Neither has instrument installers but both have connections, and have worked with well-reputed national firms specialized in instrumentation and would use them as subcontractors. 

Since P ID s are not available at this point the Instrumentation take-offs have been developed with the procedure discussed in Section 19.7. The work hours have been lifted from Section L.5 of Appendix L and broken down by process areas and offsites. The hours for instrument installation and DCS wiring were also broken down as follows as per the guidelines in Table 15.2.

The schematics of the instrument installation are shown in Fig. 9.13. The RADAIR instrument develops readouts on 4 continuous measuring channels of activity concentrations of artificial a, P, emitters and natural radon in Bq m and of the ambient y dose in pGy h. These activity concentration readouts are divided from countings in 1000 s cycles, of the activity deposited on the filter taken from samples of the surrounding air. The filter automatically advances after remaining 24 hours in front of the stack of two semiconductor detectors. The first detector located above the filter, delivers a net counting rate in proportion to the activity deposited on the filter. The... 

Apart from the instrumentation installed in the containers, advanced technology has also been developed and used for manufacturing the containers themselves, and in the field of drilling (large diameters, verticality and calibration, trajectory monitoring).
