“…According to Eq. (6), this result indicates that the HC phases have much lower steric resistance than all the other phases investigated by Snyder [44,[54][55][56][57][58][59][60]. The very low steric resistance on our HC phase is probably caused by the rather low surface density of C 8 chains (approximately 0.9 µmole/m 2 versus a typical 2-3 µmole/m 2 ).…”

“…Snyder et al developed the "hydrophobic subtraction method" to assess and compare the selectivity of RPLC stationary phases; it uses a set of 16 judiciously selected probe solutes [44,[54][55][56][57][58][59][60]. In this method, the relative retention of a given solute k'/k' EB can be dissected into contributions from various types of intermolecular interactions as expressed in Eq.…”

“…Marchand et al 91 sugerem que a seletividade das FE fluoradas comparadas com as FE alquila pode ser explicada, pelo menos em parte, como consequência da baixa polarizabilidade dos ligantes fluorados, como mensurado pelos seus baixos valores de índices de refração (IR) comparados com os ligantes alquila. Menor polarizabilidade significa interações via forças dispersivas reduzidas, com consequências para a retenção que pode ser interpretada qualitativamente em termos dos parâmetros do modelo de solubilidade, ou seja, compostos e FE com IR similares exibem interação e retenção preferencial.…”

“…Some vendors use a longer alkyl spacer chain to stabilize the phase, but this comes at the cost of making the phase more C18-like and less PFP-like. More details about fluorinated phases can be found in the papers by and Marchand et al (2005b). 5.…”

“…As a result, cyano phases can be used in highly aqueous mobile phase conditions and can retain and separate very polar compounds. More details can be found in Marchand et al (2005a). 6.…”
