Chromatography data management system

It is important to remember that by their very nature databases are constantly evolving. This gives a slightly different flavor to decisions regarding backup strategies than would be the case with a system like a chromatography data manager in which the data is, for the most part, static. 

The most common observation made by the FDA concerns the lack of (or incomplete) audit trails. This is often associated with the incorrect identification of electronic records. Specifically, the Warning Letters referred to Chromatography Data Systems (CDS), Electronic Document Management Systems (EDMS), Databases, Batch Records, Change Records, and Device History Records. 

Scope of Validation The boundaries of the validation project must be defined to ensure that there is full coverage. For example, will the analytical equipment or Chromatography Data System interfaces be validated as part of the project, will Supplier Evaluations be required, etc. It is very important at this stage to determine what is within the scope of the LIMS Validation Plan and what will be validated under other associated Validation Plans. The validation of the implementation of processes and information management within the laboratory should be managed as a cohesive whole to ensure that all parts of the LIMS are developed and validated to the appropriate standards. This may be achieved by the use of a Validation Master Plan (VMP) for all the laboratory processes and information management. The Validation Plan for the LIMS and any associated plans for other interfaced systems would be referenced in and be under the control of this VMP.

What constitutes an electronic analytical laboratory -Figure IAl-1 shows the major components of a paperles.H laboratory. First, a computerized analytical instrument is required to acquire, manipulate, and process the data. Ific instrumcnl may he connected to its own data system, as are many chromatography instruments, or directly lo an electronic laboratory notebook. The notebook ofien provides input lo a aI)oratory information management system (LI MS), as discussed in section 4H-2, and to a laboratory data-archiving system. In some cases, information from the data system or notebook flows directly into archival storage. Several of these components are discussed In this case study. 

Modem scientific data handling is multitechnique, multisystem, and manufacturer-independent, with results being processed remotely from the measuring apparatus (see Chromatography Processing of Information Electronic Laboratory Notebooks Internet-based Computational Chemistry Tools Laboratory Information Management Systems (LIMS) and Spectroscopic Databases). A prerequisite for...

The LC system consisted of a Jasco 880 PU pump (JASCO, Tokyo, Japan) for the mobile phase, a Rheodyne Model 7125 injector with a 25 pL loop, and a 0.2 x 15 cm Mightysil RP-18 GP (5 pm) column (Kanto Chemical, Tokyo, Japan). LC was performed using an aqueous solution containing 80% MeCN as the mobile phase at a flow rate of 0.2 ml/min at 26°C. The column was connected to L-7455 diode array detector (Hitachi, Tokyo, Japan) with a flow cell (17.7 pL, 10 mm), and Hitachi D-7000 advanced high performance liquid chromatography (HPLC) system manager was utilized for data acquisition. 

Ever since computers became of a practical size to fit in a spectroscopy laboratory, they have had an ever more intimate relationship with the spectrometers themselves. Spectrometer vendors have applied them to instrument control, data collection, library searching and information management. The information management functions of these systems could be considered a LIMS with a focus limited to a particular type of testing. With the exception of chromatography, these systems are limited in scope and do not interface well with laboratory-wide LIMS. Vendors...
