Modem instmmental analysis is an outgrowth of the technological advances made in physics and electronics since the middle of this century. Statistics have been with us somewhat longer, but were impractical until the advent of powerful electronic data processing equipment in the late 1960s and early 1970s, and even then remained bottled up in the central computer department. 

The technology with which cotton is now processed between the field and the mill was developed before the energy crisis, before OSHA, before EPA, before wage-and-hour laws, before open-end -spinning, before electronic data processing and before economical seed-cotton storage. That is to say that it predates factors that cause the need for advances, but it also predates the technology that will eventually lead to advances that permit cotton to meet the needs of the modern textile trade.

TSDC experiments are customarily analyzed assuming the sample behaves ohmic, i.e., the contacts do not introduce an inhomogeneous distfibution of the electric field or carrier density and a uniform bulk density of carriers extend through the entire sample. Experiments were carried out in such a way as to minimize injection effects. Contact configuration was typical for TSDC experiments. Because the currents through the sample are, in almost aU cases, extremely small, we have used a sensitive DC ammeter (model Ul-15, detection limit <10 A) with a hnear output signal. The simplest way to obtain a record of TSDC is an X-Y recorder that displays I(T) and the temperature. The equipment for the extraction of trap-spectroscopic information may be connected with devices for electronic data processing. The experimental errors in determination are less than 2%. 

One of the principal contributions of electronic data processing over the past several years in terms of chemical analysis is the saving of manual effort in interpreting analytical data. Special techniques, such as Fourier transform, have increased speed (as well as sensitivity) by orders of magnitude in connection with infrared, nuclear magnetic resonance, and mass spectroscopy, Of course, for on-line process analyses, essentially instantaneous interpretation is required to provide the proper error signal that is used to position the final control element (valve, feeder, damper, etc.). 

At present no MS manufacturer can offer complete solutions that meet the high analytical demands of a routine laboratory performing LC-MS/MS analytes. None of the mass spectrometers, let alone the complex LC-MS/MS instrument combination, is certified according to the in vitro diagnostic directive (IVDD) 98/79/EC of the European Community ( CE certified ) or FDA approved. Generally there is no bidirectional connection of the MS control and evaluation software to the laboratory s electronic data processing. The use of self-generated scripts for the transmission of work lists to the MS or for retransmission of the measured values continues to be common practice. With few exceptions (IVD-CE certified assays by some providers) the manufacture of consumables (mobile solvents, precipitants) is still in the hands of the local laboratory.

For the future, increasing dependence of hospital laboratories on mechanical and electronic data-processing techniques can be forecast. 

With the method of Fourier transform spectroscopy, the hght is not separated into spectral elements. The scientist uses a two-beam interferometer and studies the interference or correlation properties of the light as a function of path difference the results of this study are then converted mathematically to the spectrum on a computer. This conversion is a Fourier transform, which is why the method is called Fourier transform spectroscopy. All this is explained in much more detail below. The point being made here is that this method employs mathematics, computers, and electronic data processing, all perhaps strange, new tools for the... 

The main theme of this Chapter is the documentation of a TLC plate, i.e. the capture and storage of the result with the object of being able to reconstruct it. Methods used can range from simple descriptions of chromatograms to modem recording systems based on electronic data processing. 

The difference between routine laboratory work as performed today and that of 30 years ago lies not only in improved analytical methods and the benefits of electronic data processing. The main difference is the enormous paper moimtain that represents the comprehensive documentation demanded by GMP/GLP and the frustration that sometimes goes with it. 

The AMD systems 1 and 2 (without and with electronic data processing) are obtainable from CAMAG, which can provide the interested user with a series of information sheets describing various applications. 

By 1997 this is forecast to reduce to 14% because of the extraordinary growth in the Electronic Data Processing (EDP) section. The Military sector has traditionally governed the PCB market in America, but it should be noted that what is significant for the USA Military is often not desirable for the rest of the world. Companies who want to sell on a world basis may consider it more significant to be involved with other market sectors that have more universal opportunities. 

For the examination of novel samples and the initial identification and detection of steroids in complex mixtures, more elaborate techniques are required. Infrared spectra are now less sensitive and less valuable in practice than the use of the mass spectrometer. The direct coupling of the latter to GLC columns pioneered by Ryhage has provided the most powerful and chemically specific research tool now available for steroid research (E2, R6). Although LKB (Sweden) now supplies a good commercial model of the apparatus, this technique is too expensive and needs too much technical backup to be applicable to routine work outside the larger medical centers. Even so, the full exploitation of this technique outside of basic research will probably require the extensive use of automation and electronic data processing. 

The latest packaging material handling and distribution control techniques can be developed and utilized, again as models on EDP (Electronic Data Processing) equipment. This permits management again to control cost effectively and to make decisions as to the profitability and effectiveness of the distribution methods. 

Clinical instruments may also contain a feature for deproteinizing the sample. Instruments that provide only a few of these steps, primarily electronic data processing, are called semiautomatic instruments. 

Data may be recorded by electronic data processing systems, photographic or other reliable means, but detailed procedures relating to the system in use should be available and...
