Automation requirements

An alternative to TBP distillation is simulated distillation by gas chromatography. As described by Green, Schmauch, and Worman [Anal. Chem., 36, 1512 (1965)] and Worman and Green [Anal. Chem., 37, 1620 (1965)], the method is equivalent to a 100-theoretical-plate TBP distillation, is veiy rapid, reproducible, and easily automated, requires only a small microliter sample, and can better... 

Offshore oil platforms are highly automated, requiring little direct operator input to maintain production. In the event of a serious abnormality such as a fire or a gas escape, the control room worker is required to make decisions as to whether to depressurize one or more systems and which systems to blowdown. Other workers have the facility to depressurize some systems at a local control room. 

The human factors audit was part of a hazard analysis which was used to recommend the degree of automation required in blowdown situations. The results of the human factors audit were mainly in terms of major errors which could affect blowdown success likelihood, and causal factors such as procedures, training, control room design, team communications, and aspects of hardware equipment. The major emphasis of the study was on improving the human interaction with the blowdown system, whether manual or automatic. Two specific platform scenarios were investigated. One was a significant gas release in the molecular sieve module (MSM) on a relatively new platform, and the other a release in the separator module (SM) on an older generation platform.

Let us take the exposure packages as an example technically, most of these assays are highly automated, require small amount of compounds and have a brief cycle time. Scientifically, they fulfill requirements to predict exposure by addressing the three major contributing factors solubility, passive permeability and metabolic (hepatic) clearance. These type of packages are ideal to explore or diagnose scaffold characteristics and define project flowcharts. They can be used repeatedly to test newly synthesized compounds and guide SAR. A number of compounds within a... 

Most dispensing systems are custom-made to meet the method of control or degree of automation required for the particular operation. Prior to installation of the dispenser, the system should be analyzed carefully to determine what possible batching errors could occur and, with the help of the admixture supplier, they should be eliminated. Commonly available dispensing systems and controls can be discussed under three main groups - fully automated, semi-automated or manual systems. 

Today, in the pharmaceutical industry, there exists a variety of technologies to which either partial or full automation of quantitative bioanalytical steps can make the process higher throughout. However, choosing the appropriate technology to automate requires an evaluation of several parameters, including number of samples, type of samples, and time required to automate in comparison to nonautomated work flow. 

Automation requirements will not necessarily be the same for an analytical and a synthesis laboratory or from different laboratories in the same organisation. The benefits from automation need to be considered on a case-by-case basis. 

The attribution of the structure to a positive compound from a discrete library is always trivial, because the location of a particular well tells us which building blocks or reactants were added to this well during the library preparation. Scaling up discrete libraries from a few tens [7] to many thousands [8] of individuals only differs in the automation required for the preparation of large libraries, usually coupled with software recording the monomer s location in each one of the library wells. We will not deal further with this topic, but will move directly to pool libraries for their structure deconvolution. 

The mold may be split or one-piece. The finished part is removed either by splitting the mold or, in the case of a one-piece mold, by collapsing the part with a vacuum. This process can be very labor intense. However it is also automated requiring relatively no labor. Automatic systems fill molds with plastisol carried by conveyor belts through an oven as it is being slushed (the mold is put into a control motion pattern). The plastisol can gel repeatedly to a thickness of 0.06 in. (15.2 mm). The excess plastisol is poured out of the mold and automatically returned to the main tank for reprocessing. The molds proceed to another oven where curing is completed. 

One must keep in mind, though, that success in synthesis automation requires first and foremost innovative chemistry. PET radiosynthesis draws from a broad chemistry knowledgebase rooted in synthetic organic chemistry [3],... 

As discussed by Nelson (op. cit.), virtually no fractionation occurs in an ASTM distillation. Thus, components in the mixture do distill one by one in the order of their boiling points but as mixtures of successively higher boiling points. The IBP, EP, and intermediate points have little theoretical significance, and, in fact, components boiling below the IBP and above the EP are present in the sample. Nevertheless, because ASTM distillations are quickly conducted, have been successfully automated, require only a small sample, and are quite reproducible, they are widely used for comparison and as a basis for specifications on a large number of petroleum intermediates and products, including many solvents and fuels. Typical ASTM curves for several such products are shown in Fig. 13-102.

The main cost factors are represented by equipment depreciation, membrane replacement, and electric power consumption. The other costs (man power and water consumption) are of minor influence. Membrane filtration plants equipped with a low level of automation require only a few hours of attention and direct surveillance by the operator per day. Direct surveillance of membrane filtration equipment is necessary at times when batches need to be changed or during membrane cleaning. The electric power consumption is associated with the use of pumps to move the viscous yeast slurry over the membrane surface, and its estimation is relatively straight forward. 

The development of TLA and modular automation required the development of computer systems known as laboratory automation systems (LAS) with extensive software to support these systems in the clinical laboratory. For a more detailed description of the relationships between an LAS, LIS, automation equipment, and laboratory analyzers, the reader is referred to the National Committee for Clinical Laboratory Standards (NCCLS) standard on laboratory automation communications. ...

The second step of the analytical process — the components analysis or black box — can be automated by using automatic devices. The samples automatically change the automation required for this step, decreasing the time needed for the analytical process. This has been used in radiochemical analysis for operator protection. Now, automatic devices are often used for RXF, AAS, and ESCA methods, as well as for chromatographic techniques, such as HPLC, to increase the speed of the analytical process. By using automatic titration, the reliability and quality of the analytical information increases, the objectivity increases and the time needed decreases dramatically.
