Mechanisms like hydrogen bonding (in the silica floor and polar moieties, e.g. polar embedded teams such as C18-Amide or carbamate) and form selectivity (C18-PFP and C18) also are regarded. It is achievable to find out the weighting of these mechanisms on Every single stationary phase using printed described protocols and checks [2]. This helps the… Read More
