In-line quality assurance

The non-destructive character of vibrational spectroscopy techniques, such as NIR, makes them novel tools for in-line quality assurance (100). NIR has been widely used for the measurement of water in various applications (101). NIR can be applied for both quantitative analysis of water and for determining the state of water in solid material. This gives a tool for understanding the physicochemical phenomena during manufacture of pharmaceutical granulation. 

Several quantitative and qualitative tests are used for qualification of a solvent/cleaning process and for in-line quality assurance. Some tests, like the water-drop spreading test, are quick and simple. In this test, a 2 to 4 microliter droplet of water is applied to a substrate, and the contact angle it makes with the surface is measured using a goniometer. A contact angle... 

The human element Is a vital factor in all Quality Assurance Programs. It is especially critical in the more individualistic atmosphere of the laboratory as compared to a production line. Chemists must understand and appreciate the need for QA and its application to various laboratory operations. 

The variety of complex terms used in the Quality Assurance aspect of analytical measurement can be the cause of considerable confusion.This unique handbook explains the most widely-used terminology in language that is readily understood, and attempts to place each term in context. Concepts are described in a way that is useful to all practitioners, particularly those concerned with quality assurance, validation and reliability of analytical measurements. Explanations of terms are always in line with the "official definition", often developed by international committees. 

After the testing is complete and the code is corrected for errors, the software is released for production and distribution. The product is considered ready for release when it has met all the criteria specified in the quality plan and after formal sign-off by product line, quality assurance, and manufacturing management. A prerequisite for this is sufficient training of service engineers who must be able not only to install and operate the software but also to train users and answer users questions. Availability of user documentation in the... 

In line with these four points, there is a need for know-how along the entire process chain from formulas for thermoplastics through injection molding, structuring, and metallization to final placement of the electronic components. Correspondingly, in-process quality assurance with defined interfaces between stakeholders is of tremendous importance. It is in this context that this book addresses each individual process step with the purpose of avoiding possible mistakes in MID projects. 

Control charts were originally developed in the 1920s as a quality assurance tool for the control of manufactured products.Two types of control charts are commonly used in quality assurance a property control chart in which results for single measurements, or the means for several replicate measurements, are plotted sequentially and a precision control chart in which ranges or standard deviations are plotted sequentially. In either case, the control chart consists of a line representing the mean value for the measured property or the precision, and two or more boundary lines whose positions are determined by the precision of the measurement process. The position of the data points about the boundary lines determines whether the system is in statistical control. 

We will comply with NMLs policies and procedures for quality assurance activities. In addition we will develop our own ideas to improve upon NML requirements. We will set quality targets and objectives in line with corporate standards. In support of achieving customer satisfaction we will seek to achieve product conformity by carrying out quality assurance activities at all stages of vehicle manufacture - from planning through to vehicle sales. 

Economic Considerations Quality systems like the GMPs and the ISO norm do not require operations to be economical it is recognized, however, that zero risk implies infinite costs, and that the type and amount of testing should be scientifically justified such that there is reasonable assurance that a product meets specifications that are in line with the associated risks and the intended use pattern, and still are affordable.

Medicinal products and bulk pharmaceutical chemicals are produced mainly in batch processes. Controlling these products and chemicals at the end of their manufacturing processes is not in line with the general principle of quality assurance, which is that quality should be built into the product. It is then necessary to ensure that appropriate good manufacturing practices are adhered to throughout the manufacture of both bulk pharmaceutical chemicals (active ingredients as well as excipients) and medicinal products.

A variety of measurement methods have been developed for determining the water activity of food materials and are well described in texts such as Rahman (1995), Wiederhold (1997), and Bell and Labuza (2000). In general, water activity is a relatively easy parameter to measure, which can be an advantage, especially for use in the food industry. Depending on the technique selected, the water activity of a food material can be measured in a time frame of minutes (e.g., electronic instrument). In addition, individuals can be trained, with a limited amount of instruction, to make water activity measurements. Consequently, when appropriate, water activity measurements can be made relatively quickly by personnel overseeing a manufacturing line for quality assurance purposes. Measurement protocols, such as calibration procedures and proper temperature control, should be implemented to assure the accuracy of online c/w measurements. 

Since SYSCO does not itself manufacture, a quality assurance team of more than 180 professionals determines specifications for each own-brand item and also sets criteria for raw materials and for the standards that manufacturers and processors must follow for food safety, quality, and consistency, as well as for social responsibility and supplier codes of conduct. This quality assurance team identifies and establishes supply sources and audits those suppliers to enforce SYSCO s strict standards for various factors like facility conditions and sanitary measures. Inspectors are at the plants as bacon comes off the production line, or follow produce from field to cooler to assure proper holding temperatures and product integrity. SYSCO s program is unmatched in the food industry. The number of people and level of resources committed to supporting the integrity of the products are far superior to those of other industry competitors, who may devote merely a handful of personnel to these tasks, if they are undertaken at all.
