Quality aspects

Zinc ferrites are excellent general-purpose pigments of yellowish brown color. As opposed to iron oxide yellows, zinc ferrites offer higher heat stabiUty and can be used in plastics and coatings cured at temperatures above 120 °C. Zinc ferrites are coloristically not as clean as rutile yellows. Zinc ferrites can be sUghdy magnetic.

Safety and quality aspects are the main topics that must be addressed from a regulatory perspective at the pre-clinical phase of drug development. Indicative efficacy data will also be obtained, but authoritative data can be obtained only from clinical studies conducted with humans. Safety and preliminary efficacy indications... 

There is a draft guideline that includes information relating to the quality aspects of medicinal gases (CPMP/QWP/1719/00 draft, released for comment in July 2000). This includes several points of relevance to the description of the product and to development pharmaceutics.

If both the farms and the dairy are covered by a reliable control system, the everyday monitoring will take place at the optimal CCP at the farm and analysis of milk samples at the dairy will only be needed at low frequency for verification of the system (Principle 6). This will ensure that there are no antibiotic residues in the milk sold by the dairy, with minimal expenses for control. In fact, the most expensive item will be the cost of the unannounced inspections at the farms to monitor the integrity of the system. However, if not all the farms are covered by a sufficiently good control system, the dairy will have to add the extra costs of its own independent system, in order to be able to take responsibility for this quality aspect. So the main benefit of a supply chain-based system is that it provides full control at the lowest cost. The main drawback is that the more entities that are involved, the greater is the risk that one of them will experience a system failure and this can have disastrous consequences for all those other entities that rely on the defaulting entity for their product control.

Whether the mentioned needs in our production systems can be met by organic agriculture is still unknown and under discussions. This article is a review of some of the current state of knowledge regarding ecological, environmental, food safety, human health and quality aspects of organic agriculture. 

Evaluate the result in relation to quality aspects, including those not readily expressed as postconditions, such as error rate, cycle time, and costs. In the end, this technique can only suggest alternatives. Human, political, and many other constraints will influence the decision. 

As mentioned above the quality policy is one of the most important parts of the quality manual. The whole system should only reflect and realize the quality statements and requirements in the daily work. The policy shall be authorized by the top management, because this statement has to reflect clearly, how cracial quality aspects are in the work of the laboratory.

A systematical approach of sample preparation methods and optimisation of the quality aspects of sample preparation may enhance the efficiency of total analytical methods. This approach may also enhance the quality and knowledge of the methods developed, which actually enhances the quality of individual sample analyses. Unfortunately, in bioanalysis, systematical optimisation of sample preparation procedures is not common practice. Attention to systematical optimisation of assay methods has always been mainly on instrumental analyses problems, such as minimising detection limits and maximising resolution in HPLC. Optimisation of sample extraction has often been performed intuitively by trial and error. Only a few publications deal with systematical optimisation of liquid-liquid extraction of drugs from biological fluids [3,4,5]. 

One of the quality aspects of analytical chemical methods is whether they are rugged or robust against extraneous influences or changing conditions. The latter can be a change in analist performing the analysis or a change in instrument, laboratory, supplier of chemicals etc.
