Nevertheless, it may be seen (Table 11) that the intercept obtained (and therefore the purity evaluated) is not markedly influenced by the choice of activ
The separation of eight kinds of food preservative by one-and two-dimensional chromatography on polyamide layers was investigated. A comparison was made between the detection limits on polyamide and silica gel layers, and the superiority of the polyamide thin layers was confirmed. The separation o
