Quality records authentication

The filing provisions you have made should enable your records to be readily retrievable however, you need to maintain your files if the stored information is to be of any use. In practice, records will collect at the place they are created and unless promptly removed to secure files may be mislaid, lost, or inadvertently destroyed. Once complete, quality records should not be changed. If they are subsequently found to be inaccurate, new records should be created. Alterations to records should be prohibited as they bring into doubt the validity of any certification or authentication as no one will know whether the alteration was made before or after the records were authenticated. In the event that alterations are unavoidable due to time or economic reasons, errors should be struck through in order that the original wording can still be read, and the new data added and endorsed by the certifying authority. 

For reliable creation of the RI library, all RIs of authentic chemicals determined by the Finnish Institute for Verification of the CWC (see Appendix 1, columns I, II, VI, and VIII) are checked against the RIs of special test chemicals obtained under the same operating conditions. The RIs of library chemicals determined at the beginning and at the end of the library creation must be comparable and consistent. The RI values of test chemicals in Table 2 are the mean values recorded during the creation of the RI library by running the test solution after every sixth run. This practice ensures the quality of the library and the analyst can estimate the correctness of the recorded RI values, by running first the test solution and comparing the RI values of the test chemicals with those presented in Table 2. 

The Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) describes the quality system as consisting of all efforts devoted to produce quality results that are authentic, appropriately documented, and technically defensible (EPA, 2000c, Chapter 9). The purpose of the quality manual or QAP is to describe, in a single document, all elements of the quality system. This includes all laboratory policies regarding quality and all of the QA measures implemented by the laboratory. Some records may be included in the QAP itself, while others are filed as specified in the QAP. The QAP defines every element of laboratory operation and represents the laboratory s commitment to quality. The interconnected elements of QA policy that must be included in the QAP are... 

The second part of the book—Chapters 9-12— presents some selected applications of chemometrics to different topics of interest in the field of food authentication and control. Chapter 9 deals with the application of chemometric methods to the analysis of hyperspectral images, that is, of those images where a complete spectrum is recorded at each of the pixels. After a description of the peculiar characteristics of images as data, a detailed discussion on the use of exploratory data analytical tools, calibration and classification methods is presented. The aim of Chapter 10 is to present an overview of the role of chemometrics in food traceability, starting from the characterisation of soils up to the classification and authentication of the final product. The discussion is accompanied by examples taken from the different ambits where chemometrics can be used for tracing and authenticating foodstuffs. Chapter 11 introduces NMR-based metabolomics as a potentially useful tool for food quality control. After a description of the bases of the metabolomics approach, examples of its application for authentication, identification of adulterations, control of the safety of use, and processing are presented and discussed. Finally, Chapter 12 introduces the concept of interval methods in chemometrics, both for data pretreatment and data analysis. The topics... 

The Level II Procedure reviewed provides a detailed description of how RRD will control and maintain all controlled documents for which they are responsible. In addition, processing of changes to their controlled documents is also described. Technical adequacy and quality assurance in the preparation of a document are the responsibility of each originating organization and ultimately of the authenticator of each document. Those documents designated as QA records are identified as such.
