Packaging of instruments

NASA s most recent comet missions are Deep Impact and Rosetta. Deep Impact was launched on January 12, 2005, with Comet Tempel 1 as its target. The spacecraft encountered Tempel 1 on July 3, 2005, at which time it released a 770-pound (350 kg) copper projectile at the comet. Cameras and spectrometers on the spacecraft photographed and collected samples of materials ejected from the comet nucleus and relayed that information to scientists on Earth. Rosetta was launched on March 2, 2004, with Comet 67P/Churyumov-Gerasimenko as its target. The spacecraft will orbit the comet and make observations for about two years as the comet approaches the Sun. It will also release a small package of instruments that make the first-ever landing on the surface of a comet. 

Complex chemical systems are composed of one or more components in a mixture with a significant degree of spectral interference, or of several components with a large amount of mutual physical and/or chemical interaction. In these cases, quantitative analysis is best performed by statistical methods such as principal component regression (PCR) or partial least squares (PLS) [36] these are offered in the software packages of instrument manufacturers and software suppliers. Artificial neural networks (ANNs) should be primarily used when a data set is nonlinear [37]. 

FEP, fault tree, gvent tree and piping instrumentation diagram (P ID) editor, accesses ihe package of graphical tools for risk assessment. These tools include the event tree, fault tree and P ID graphical editors. The event tree and fault tree editors are in PSAPACK the P ID editor is in FEP. The event tree editor is used for graphical construction and modification of event trees. The fault tree editor does the same for fault trees the P ID editor does the same for construction and modification of P IDs used in a PSA.

Manufacturers of today s modem NMR spectrometers normally offer a number of different models of instruments that are capable of measuring solid state NMR spectra. Usually, a dedicated solid state NMR instrument is available along with solution-phase models that are capable of solids work with the purchase of an additional solids accessory package. For any pharmaceutical company that is contemplating the purchase of an NMR for solids work, it is this author s opinion... 

In order for the data generated by the analyzer to be useful, it must be transferred to the operation s centralized control or host computer and made available to process control algorithms. Vendor packages manage instrument control and can do spectral interpretation and prediction or pass the data to another software package that will make predictions. Most vendors support a variety of the most common communications... 

The specifier must have a good understanding of instrumentation and support machinery. Any process instrumentation book will acquaint the newcomer to this area with the criteria for proper instrumentation selection. To illustrate the process involved in specifying the entire cooling tower system package, the following example has been prepared. 

Spectral Manipulation Techniques. Many sophisticated software packages are now available for the manipulation of digitized spectra with both dedicated spectrometer minicomputers, as well as larger main - frame machines. Application of various mathematical techniques to FT-IR spectra is usually driven by the large widths of many bands of interest. Fourier self - deconvolution of bands, sometimes referred to as "resolution enhancement", has been found to be a valuable aid in the determination of peak location, at the expense of exact peak shape, in FT-IR spectra. This technique involves the application of a suitable apodization weighting function to the cosine Fourier transform of an absorption spectrum, and then recomputing the "deconvolved" spectrum, in which the widths of the individual bands are now narrowed to an extent which depends on the nature of the apodization function applied. Such manipulation does not truly change the "resolution" of the spectrum, which is a consequence of instrumental parameters, but can provide improved visual presentations of the spectra for study. 

This case study embraces the design and validation of both standard and intelligent instrament applications, and briefly discusses special instrament systems (shutdown systems and analyzer packages). The number of instruments that can be involved with the dynamic operation of a pharmaceutical manufacturing process can be large (2000 to 3000 items). In most cases, they are... 

The sampling of nuclear materials and the packaging of samples are very critical steps in the measurement process. Differing conditions at nuclear plants dictate the need for a variety of sample-taking and handling procedures before samples are sent for analysis. SAL has developed a set of procedures that take account of local conditions, and has been instrumental in improving the overall quality of the verification of uranium and plutonium samples.
