Broad spectrum analysis strategy

The identification of all or most substances in one or more chromatograms, even with extensive spectroscopic data, can be a challenging and difficult process. The available data may not be sufficient to even tentatively identify all the components, especially if pure authentic samples of suspected substances are not available in the laboratory. Calibration of a broad spectrum method for quantitative analysis is delayed until the desired components are identified. For these reasons, and the general preoccupation with target analytes, the BS strategy is much less common than the target analyte strategy. 

The chemical analysis strategy, that is, a total, target analyte, or broad spectrum determination...
