Figure 1: Three-tier testing approach to media fingerprinting. Figure 3 describes how the methods from a number of detectors can be utilized for classical targeted/quantitative fingerprinting or untargeted fingerprinting using multivariate data analysis. We don't count on that low-stage vitamins or hint elements could be detected by these strategies. In theory, Raman and IR are sensitive to most chemicals; nevertheless, these strategies will solely be sensitive sufficient to detect the compounds present in larger concentrations within the media that, usually, can be predominantly buffer and amino acids supplier acids.
