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. 

Record keeping is an essential requisite of good market research. In the chemical field, call reports or visit reports are usually written by the interviewer and become part of the report in some cases and certainly should become part of the company or consultant files for future reference. Obviously, the call report serves a valuable purpose in the analysis and writing stage. Some market researchers have also found that cross-referencing call reports over a period of time allows rapid identification of the respondents who have demonstrated the greatest abiUty in forecasting their company needs and/or the needs of their industry. 

Whereas issues of technician productivity, sample status, and scheduling of analyses are economically important, these take second place to the issue of measurement quaUty in the laboratory. LIMS software enables activities such as cahbration and proper maintenance to be scheduled automatically. By recording the results of these activities in the LIMS, the data to demonstrate proper performance are readily made available. Additionally, the schedule can be adjusted to reflect the actual needs of the individual instmments.

Conventionally, Auger spectra are presented in the differentiated energy distribution form dN(F)/dF, rather than in the undifferentiated form N(E) used in XPS. Differentiating enhances the visibility of Auger features, as is demonstrated in Fig. 2.20, in which the differentiated spectrum from boron is shown above the corresponding N(E) spectrum. The N(E) distribution is nowadays recorded digitally, and differentiation is performed by computer. With the rapid improvement in the signal-to-noise... 

Because of the limited energy resolution in EDX spectra an overlap of peaks can often occur, depending on the composition of the material to be analyzed. The situation is much improved in WDXS, for which the energy resolution is approximately 10 eV and better. This is demonstrated in Fig. 4.25, in which the WDX and EDX spectra recorded from BaTi03 are compared. Here, WDXS enables easy resolution of the Ba-La and Ti-Ka lines this is impossible by EDXS. In addition, for WDXS the...

The standard does not require you to demonstrate that you meet all the requirements of the standard. It only requires a quality system to be documented, implemented, and maintained. While clause 4.16 on quality records does in fact require you to demonstrate the effective operation of the quality system, it does not dictate how you should... 

While procedures should define the quality records that are to be produced, these are the records that will be produced if these procedures are used. On particular contracts only those procedures that are relevant will be applied and therefore the records to be produced will vary from contract to contract. Special conditions in the contract may make it necessary for additional quality records. Records represent the objective evidence with which you are going to demonstrate compliance with the contractual requirements. It would therefore be expedient, although not essential, to list all the records that will be produced and where they will be located. The list does not need to detail every specific record, providing it identifies types of records and all new records to be produced. 

The records of all tests, inspections, analyses, and demonstrations should be generated which demonstrate that the process is safe, meets environment legislation, is reliable, stable, capable, and maintainable and produces products that meet engineering standards. The next step is product approval.
