Figure 1: Three-tier testing strategy to media fingerprinting. Figure three describes how the methods from a number of detectors can be used for classical targeted/quantitative fingerprinting or untargeted fingerprinting using multivariate information analysis. We don't expect that low-stage vitamins or hint parts could be detected by these strategies. In principle, Raman and IR are delicate to most chemicals; nonetheless, these methods will only be sensitive enough to detect the compounds current in greater concentrations within the media that, generally, will probably be predominantly buffer and organic amino acids supplier acids.
