E.C., and I.T. sources, which can be purchased commercially. The Coulomb, (n, y), and (d, p) reactions require access to very expensive equipment. For routine chemical applications particularly, sources having lifetimes of months or years are preferable so that prolonged series of experiments become both economical and self-consistent. 

Improved sensitivity and detection limits were reported by Tanabe et al. (1980) by use of the 185 nm resonance line and an argon-purged monochromator and reaction vessel. The applicability of the equipment for routine analysis is probably problematic. 

Acid foods generally require the simplest equipment for heat preservation. The food can be heated to 100°C and filled hot into suitable containers. The containers are sealed, inverted to sterilize the closure, held at the filling temperature for a short time to ensure that the package is thoroughly heated, and then cooled. Tomato sauces, jellies, fmits, fmit juices (qv), and pickles are routinely preserved in this fashion. 

Fire and uncontroUed polymerization are a concern in the handling of chloroprene monomer. The refined monomer is ordinarily stored refrigerated under nitrogen and inhibited. This is supported by routine monitoring for polymer formation and vessel temperature. Tanks and polymerization vessels are equipped for emergency inhibitor addition. Formalized process hazard studies, which look beyond the plant fence to potential for community involvement, are routine for most chemical processes. 

Analyst Analysts must have a firm understanding of the operation of the unit. If they are not involved in the day-to-day operation or responsible for the unit, more preliminaiy work including process familiarization, equipment familiarization, operator interviews, and constraint hmitations will be required. Even when an analyst is responsible, a review is necessaiy. Analysts must firmly estabhsh the purpose of the unit test. Different levels require different budgets, personnel, and unit commitment. Additional resources beyond that required for routine measurements must be justified against the value of the measurements to the establishment of the understanding of the plant operation. 

Measurements of the characteristic X-ray line spectra of a number of elements were first reported by H. G. J. Moseley in 1913. He found that the square root of the frequency of the various X-ray lines exhibited a linear relationship with the atomic number of the element emitting the lines. This fundamental Moseley law shows that each element has a characteristic X-ray spectrum and that the wavelengths vary in a regular fiishion form one element to another. The wavelengths decrease as the atomic numbers of the elements increase. In addition to the spectra of pure elements, Moseley obtained the spectrum of brass, which showed strong Cu and weak Zn X-ray lines this was the first XRF analysis. The use of XRF for routine spectrochemical analysis of materials was not carried out, however, until the introduction of modern X-ray equipment in the late 1940s. 

Some niekel eompounds may be irritant to skin and eyes and dermal eontaet with niekel ean result in allergie eontaet dermatitis. Niekel earbonyl is extremely toxie by inhalation and should be handled in totally enelosed systems or with extremely effieient ventilation. Air monitors linked to alarms may be required to deteet leaks. Respiratory equipment must be available for dealing with leaks. Biologieal eheeks (e.g. niekel in urine) should be eonsidered for routine operations involving niekel eatalysts. 

The accident resulted from a routine safety test of some electrical control equipment at the start of a normal reactor shutdown for routine maintenance. The test was to determine the ability to continue to draw electrical power from a turbine generator during the first minute of coast-down following a station blackout. In a blackout, the reactor automatically scrams and diesel generators start to assume load (about 1 minute required). 

Active matter (anionic surfactant) in AOS consists of alkene- and hydroxy-alkanemonosulfonates, as well as small amounts of disulfonates. Active matter (AM) content is usually expressed as milliequivalents per 100 grams, or as weight percent. Three methods are available for the determination of AM in AOS calculation by difference, the two-phase titration such as methylene blue-active substances (MBAS) and by potentiometric titration with cationic. The calculation method has a number of inherent error factors. The two-phase titration methods may not be completely quantitative and can yield values differing by several percent from those obtained from the total sulfur content. These methods employ trichloromethane, the effects from which the analyst must be protected. The best method for routine use is probably the potentiometric titration method but this requires the availability of more expensive equipment. 

While much care has to be used in performing competitive protein binding assays, most well-equipped and staffed clinical laboratories should have no serious problem in undertaking such assays. The biggest problem that may be encountered is the selection of a dependable and reliable manufacturer for reagents. Problems that may arise are non-purity of standards and label non-specificity of antibodies or the inability to maintain any of these characteristics from lot to lot. It therefore is a good practice to evaulate a few manufacturers before selecting one for routine use. 

The manufacturing process must be fully defined and capable of yielding, with the facilities available, a product that is microbiologically acceptable and conforms to its specifications. This demands that a process be sufficiently evaluated before commencement to ensure that it is suitable for routine production operations. Processes and procedures should be subject to fiequent reappraisal and should be re-evaluated when any significant changes are made in the equipment or materials used. 

Other considerations could include availability of reagent(s) or equipment, method for routine analyses vs limited samples, and confirmatory method vs multi-residues. Plan for method validation and/or analytical quality control. 

Whereas the components of (known) test mixtures can be attributed on the basis of APCI+/, spectra, it is quite doubtful that this is equally feasible for unknown (real-life) extracts. Data acquisition conditions of LC-APCI-MS need to be optimised for existing universal LC separation protocols. User-specific databases of reference spectra need to be generated, and knowledge about the fragmentation rules of APCI-MS needs to be developed for the identification of unknown additives in polymers. Method development requires validation by comparison with established analytical tools. Extension to a quantitative method appears feasible. Despite the current wide spread of LC-API-MS equipment, relatively few industrial users, such as ICI, Sumitomo, Ford, GE, Solvay and DSM, appear to be somehow committed to this technique for (routine) polymer/additive analysis. 

Table 8.40 compares the main characteristics of WDXRF and EDXRF. Multidispersive XRF combines the benefits of the WDXRF technique for routine elemental analysis with the complete flexibility offered by EDXRF for nonroutine analysis. Clearly, modem XRF instrumentation is rather varied, ranging from simple benchtop EDXRF equipped with a low-power X-ray tube and high-resolution proportional counter for some key elements, to 4 kW simultaneous multichannel spectrometers with 28 fixed element channels for... 

Together these subsystems can give rapid distinction of bacteria at near strain level after a single working day s operation, meaning less than eight hours from the time a sample arrives at the lab. The equipment is expensive. Flowever, the cost per analysis is low due to automation and rapid operation. Enormous benefits could obtain from the availability of such integrated, automated systems for routine analyses in clinical or public health laboratories. 

The smallest pores that can be observed using this approach depend on the highest pressure to which the mercury can be subjected in a particular piece of equipment. Volumes corresponding to pore radii as small as 100 to 200 A can be measured with commercially available equipment. Beyond this point the pressures required to fill up the capillaries with smaller radii become impractical for routine use. Unfortunately, there are many catalysts of industrial significance where these very small capillaries contribute substantially to the specific surface area. Special research grade mercury porosi-meters capable of measurements down to 15 A radii have been developed but, for routine measurements, the desorption approach described below is more suitable. 

Although the power of research MRI/MRS machines for human use can be as high as 9.4 T, the FDA has imposed a limit of 3 T for routine clinical human use. Industrial manufacturers of MRI equipment are very careful to conform to all the FDA guidelines regarding magnetic field strength, gradient speed and RF power (see Appendix Basic principles of MRI). 

Thus, the systems used to monitor and control the process are conventional. Process materials (with the exception of agents and energetics), temperatures, and pressures used in this technology package are commonly used in other industrial applications, where they are routinely monitored and controlled. The usual collection of equipment for monitoring temperature, pressure, level control, flow, and other parameters normally measured in a chemical plant is used. The analytical procedures to be used to monitor certain streams will be new, and they present the greatest uncertainty. 

Aseptic BPS machines are subject to steam-in-place sterilization following standard CIP cycles. The SIP cycles are routinely measured by thermocouples located in fixed positions along the product pathway. Validation of SIP cycles should be carried out to demonstrate that consistent sterilization temperatures are achieved throughout the equipment to prove that the system can be effectively sterilized. Validation should also identify suitable positions for routine use, or justify the fixed probe positions already in place. The SIP validation is generally carried out with the help of additional thermocouples and should include the use of biological indicators (appropriate for moist heat sterilization). Test locations should include areas which may be prone to air or condensate entrapment. An accurate engineering line drawing of the system to aid identification of suitable test locations and document test locations selected should be available.
