Drafts, condensation on windows, ice damming, excessive noise from outdoors or equipment operation, and rooms that are cold in winter and hot in summer will diminish comfort in a home. Air-sealed construction, improved insulation, high-performance windows, right-sized, efficient hcating/cooling distribution systems, and mechanical ventilation commonly found in energy-efficient homes all work together to effectively eliminate these problems. 

Procedures used in a laboratory must be recorded for easy reference, down to the smallest detail. An analytical laboratory will often use standard procedures from official publications, but to these must be added references to specific types of equipment used. As a result, a laboratory needs its own procedure manual to use in day-to-day work. Every operation should be described in detail, with references made to official methods where applicable. It takes thought and skill to write such a manual in a manner that will make is useful to all workers. Safety measures, where needed, must be included. Simple operations, such as the preparation of reagent solutions, should be specified.

In this Chapter we describe the construction of various pieces of apparatus by the methods of glass-working already described. All the apparatus mentioned below can be made by quite simple methods and without the use of the expensive items of glass-working equipment such as lathes, ovens, various wheels and so on. Many pieces of complex-looking apparatus are made merely by a succession of simple operations. 

The size range of commercial aerosols and the methods available for determination of particle size and for removing the particles from the gas are shown in Figure 1.50, which is taken from the work of Ashman. It may noted that the ranges over which the various items of equipment operate overlap to some extent, and the choice of equipment depends... 

Chemical process equipment is basically the same now, as it was in the 1930 s, or at least the 1950 s. The trays, K.O. drums, compressors, heaters, steam systems have not - and probably will not change. The fundamental nature of process equipment operation has been well established for a very long time. Modern methods of computer control, and process design have not, and cannot, change the basic performance of the bulk of process equipment. These tools just seem to have made learning about the working of the equipment more difficult. 

Inspection and observation of the work environment enables the auditor to help local management identify work hazards resulting from unsafe design, lack of protective features, or exposure to materials in or evolving from the process. It also provides an opportunity to observe work practices and equipment operations. 

In recent years h.p.l.c. has become a valuable chromatographic tool for analytical and preparative scale work. In this latter area the separation of isomers (structural, diastereoisomeric, and enantiomeric) has been possible by the selection of appropriate column packing material and solvent systems. However, the equipment, operating costs, and column packing materials are more expensive than those in t.l.c., g.l.c. and conventional liquid-solid column chromatography.

The experiment is carried out using a glass column suitable for high-pressure work, equipped with a protective shield. Reconunended is the Waters AP-1 10-mm X 100-mm glass column from Waters Corporation, part number WAT021901. The column is packed with a fully porous silica. A particle size of 30/im is recommended. This keeps the packing procedure simple, maintains a low operating pressure, but still allows you to obtain narrow bands. The mobile phase is a mixture of 59% toluene and 41% methanol. An HPLC instrument is required for the demonstration. 

Confidence in the continued on-specification operation of the asset is increased. By early detection of wear, you can plan for and take corrective action to retard the rate of wear or prevent or minimize the impact of failure. The corrective maintenance work restores the component or subassembly to a good state of repair. Thus, the equipment operates with a greater probabiUty of trouble-free performance.
