Unique identification

A database management system (DBMS) is used by most LIMS systems for storing data. Examples of commercially available DBMS are DB2, DBASE, Informix, INGRES, ORACLE, and RDB. AH of these DBMS conform to the "relational" model developed by Codd (19). Eigure 3 demonstrates the use of a relational DBMS for storing LIMS data. Here data is grouped by type so customer and analysis requests are stored separately from sets of sample information which are, in turn, stored separately from sets of analysis results. Individual records are linked or related by unique identification data. 

The Brookhaven Protein Data Bank, PDB (http //www.pdb.bnl.gov), is the primary store of experimentally determined atomic coordinates of proteins. Each coordinate set has a unique identification code that can be... 

The standard requires that where, and to the extent that taceability is a specified requirement, the supplier is to establish and maintain documented procedures for unique identification of individual product or batches and goes on to require this identification to be recorded. 

The standard requires the supplier to define the process employed for the calibration of inspection, measuring, and test equipment, including details of equipment type, unique identification, location, frequency of checks, check method, acceptance criteria, and the action to be taken when results are unsatisfactory. 

Specific information on the handling of the processed fractions may also be included. Specific containers or types of containers may be required to minimize analytical interference. Sample identification numbers may be assigned in the protocol or may be generated by the processing facility. In either case, each processed fraction should have a unique identification number to reduce confusion at the processing facility and at the analytical laboratory where the residues will be determined. 

When a sample is received it should have a unique identification, i.e. a number or code. All details about the sample should be recorded. This will include storage conditions and, if it is necessary to transfer the sample from person to person, this should be fully documented. Details of the container and closures should also be recorded. These may have been inappropriate and influence the analytical result. The appearance of the sample on receipt should also be documented. 

A quant has a unique identification. Any quant in a model can be identified by this identification. The identification is called the quant-ID. 

Object attributes are represented by columns in the table. Each session, instmctor, and client is assigned a unique identification tag, ID, which is used to implement links between the objects. Links between objects are represented by columns that contain the ID of the corresponding linked object. 

Record keeping carried out not only by the analyst in laboratory notebooks, but also in logbooks for each instrument. After completion, these should be archived for at least ten years. Records should include the type of sample (with a unique identification number), collection method, location, date, description of sample, preparation and analysis method, and instrumental conditions, original data files, and the name of the person responsible. 

Larry Arnold of the National Soil Survey Laboratory assigns unique identification labels to soil samples in preparation to logging the samples and their unique field information into a LIMS. 

For protein crystallography, the repository of most protein crystal structures is the PDB hosted at http // www.rcsb.org/pdb/ (Berman et al., 2000). This database contains the 3-D coordinates (and sometimes the structure factor files) for almost all protein crystal structures. Most journals currently require deposition of the coordinates when pubhshing stmcture papers. Each structure is given a unique identification code that will be listed in the paper (see Figure 22-1 for examples of PDB codes). Structures can be accessed using this code, or using various other search criteria. The PDB also contains structural information for NMR structures. 

Electrothermal vaporization has many appHcations relating to ICP analysis the abihty to vaporize solvents and to handle small soHd or viscous samples are particularly important. In addition, the measurement of the isotopic ratios of lead in various ores provides a unique identification of the ore and its source. Now that commercial systems are available, the technique will undoubtedly become popular. These techniques seem to have found favour, particularly in Japan. 

In chapter 5.10.2 of ISO/IEC 17025 the form of the test reports and calibration certificates are specified in detail. The first points (title, name of laboratory and client, serial number, method) are necessary to guarantee unique identification. 

Each study is given a unique identification and it is conducted in accordance with the study plan. The analyst that performs the tests has the responsibility to record the laboratory data promptly, accurately and legibly. Any changes in the raw data should be made so as not to obscure the previous entry, should indicate the reason for change and should be dated and signed or initialled by the person making the change. 

ISO/IEC 17025 requires a unique identification of all management system documents with the date of issue, revision identification, page numbering, total number of pages on each page and the issuing authority. 

When large numbers of crystals are examined at s)m-chrotron beamlines, unambiguous identification of the samples is critical. The SPINE standard includes a unique barcode on the magnetic base for that purpose. However, the SPINE protocol also assumes that the bases will be reused. Hence, these 2D barcodes alone do not permit unique identification of a given crystal.

In addition to a health care provider s unique identification number, some states require that prescriptions for controlled substances be written on tamper-resistant security prescription forms. The purpose of this legislation is to prevent forgeries and to tighten the control of prescription order forms. 

The HBA/HNA system provides a more suitable system for study, since it is prepared by melt polymerization of the two monomers and is far more stable at elevated temperatures compared to the PHBA/PET. The HBA/HNA copolymers are soluble in pentafluorophenol permitting use of NMR techniques to characterize diad sequences. In Fig. 13b,c the 13CNMR spectrum of the carboxyl carbon region of the HBA/HNA copolyesters of the 73/27 and 48/52 systems is shown [34]. Also shown in Fig. 13a,d are the spectra of 13C enriched HBA and HNA containing copolymers permitting unique identification of the diad sequences. As a result of this technique it was possible to determine the reactivity ratios of the two monomers by analyzing the 50/50 copolymer after polymerization to a molar mass value of 2000 [35]. Examination of the copolymer by 13C NMR showed the same ratio of monomers as in the starting... 

The unique identification of the product (see 4.2.4) is controlled and recorded by assigning a specific batch number to each product. 

When traceability is specified, the product or parts have unique identification. 

Where, and to the extent that, traceability is a specified requirement, individual products or batches have a unique identification. This identification is recorded (see 4.16). 

Clearly, this sequence does not provide a unique identification of the surface site(s) that is associated with the increased catalytic activity. Carbon monoxide chemisorption provides the additional information required for this determination. Based on well-established steric considerations (124), the surface sites can also be arranged in an order of decreasing CO chemisorption ability (165) ... 

Each collected sample must have its own unique identification number. The project staff will use this number to track the sample in the field and at the home office during the project assessment phase. The laboratory will use this number for matching the sample and the requested analysis. The laboratory will enter the field sample IDs into the data base and assign the samples with laboratory IDs for internal tracking. Analytical results will be reported for the samples identified according to their field and laboratory IDs.
