THERE is an increasing tendency on the part of organic chemists to apply the Berzelius dualistic theory, in a modified form, to organic compounds. In many theories of valency, individual groups are ...

Kinetex 2.6 µm Polar C18 combines C18 ligands with a polar-modified surface to enable superior retention of polar and nonpolar compounds while ensuring 100 percent aqueous stability.Click here for ...

The effect of long-chain polar compounds on the coefficient of kinetic friction under boundary conditions has been studied using the Boerlage four-ball friction apparatus in various modifications.

The first is the new Luna Omega Polar C18 stationary phase – a unique selectivity on an innovative silica particle that delivers a wide elution window and combined high retention for polar and ...

Phenomenex has launched mixed-mode selectivities and particle sizes for UHPLC, HPLC and preparative work in the Luna column range. Luna Omega columns are suited for applications including drug ...
