Limits of detectability for the desired elemental analyses vary depending upon the matrix, elements, methods of sample preparation, and quality of instrumentation applied. Generally, these are on the order of 1 to 100 parts per million. The limit of detectability, however, is only one criterion in evaluating methods of analysis. The liiue of analysis is important, particularly in production and process control laboratories, in multi element spectrometers, it is possible to perform as many as 30 simultaneous elemental determinations in from 20 to 120 seconds, depending upon the material being analyzed.

Specialized equipment for industrial measurements and automatic control have been developed (18) (see Process control). In general, the pH of an industrial process need not be controlled with great accuracy. Consequendy, frequent standardization of the cell assembly may be uimecessary. On the other hand, the ambient conditions, eg, temperature and humidity, under which the industrial control measurements are made, may be such that the pH meter must be much more robust than those intended for laboratory use. To avoid costiy downtime for repairs, pH instmments may be constmcted of modular units, permitting rapid removal and replacement of a defective subssembly. 

Process monitoring, both in the laboratory and on the production line, is an important appHcation of infrared spectrometry (see Process control).

Annual iadirect costs are estimated as percentages of the direct labor and fixed capital costs. Typical direct labor percentage ranges are 25—30% for payroll overhead, 15—20% for stores and suppHes, 10—20% for control laboratory, 10—20% for security, 10% for yard, and 10—15% for process improvements. That is, total iadirect costs are usually 80—115% of the direct labor cost (1).

Physiological or biochemical changes have been observed in plants exposed to air pollutants, including alterations in net photosynthesis, stomate response, and metabolic activity. Such exposure studies have been conducted under controlled laboratory conditions. An understanding of the processes involved will help to identify the cause of reduction in yield. 

Special, fully automated one-task XPS instruments are beginning to appear and will find their way into both quality control laboratories and process control on production lines before long.
