From this model, two criteria are developed in order to estimate the precision of the method: the repeatability and the reproducibility, respectively noted . and . In addition the princi

This modelling confers a fairly flexible structuring capability for data retrieval and validation. The basic theory of entity-relationship modelling is presented and illustrated for two typical environmental st

Of specific interest to chemometricians is the data analysis area of the LIMS model; here standard chemometric tools can be used such as PCA, PCR etc. to reduce data to information. The LIMS will aid the process by ordering the

Empirical Pattern Recognition/Expert System Approach for Classification and Identification of Toxicl class, a molecular weight estimate and a lower limit to the molecular weight for a given spectrum. This system has been extensively tested with 630 reference spectra from two databases and with 37 GC/MS field spectra. Classification and identification accuracies were 95–97%. Median absolute deviat
