“…More recently, Tanaka and co-workers, 56 Engelhardt and Jungheim 57 and NIST 58 tests have also been used, to permit comparisons with data from the literature. 59 The initial chromatographic results obtained with the first PMOS phases were very promising, taking into account, primarily, the low cost and simplicity of their preparation. In a subsequent study, the same authors evaluated the chemical stability of the PMOS phase through the monitoring of chromatographic parameters of some of these same compounds while passing a mobile phase of methanol:water (50:50, v/v) through the column.…”

“…Although PCA and HCA have been frequently applied to find similarities among particular chromatographic conditions [1,8,9], or specific chromatographic columns, the non-supervised character renders an ambiguity to the pattern. The main disadvantage of PCA is a loss of information with consecutive reduction of dimensionality by projecting data only to few principal components.…”

“…Euerby et al [79][80][81] avaliaram 229 fases estacionárias, de diversos tipos, como C8, C18, diol, aqua, grupo polar embutido, fenil, fenil-hexil etc., utilizando o teste de Tanaka. 26 Dos seis parâmetros avaliados com o teste de Tanaka, observa-se que o parâmetro CH 2 não é útil para avaliar as fases estacionárias devido ao seu baixo DPR, de apenas 9% (DPR alto significa que o parâmetro cromatográfico estudado varia consideravelmente de uma fase estacionária para outra).…”
