Synergi Polar

Finally, other highly polar phases can be thought of such as various fluorinated phases, Zorbax Bonus RP, or Synergi POLAR RP.

Those possessing enhanced polar selectivity, as shown by a high hydrogenbonding capacity (i.e., a p values > 1), e.g.. Platinum CjglS EPS, Synergi Polar RP, Zorbax SB AQ, and Aquasil phases (column nos. 75, 105, 134, and 5, respectively) - group A. 

As early as the visual comparison of the chromatograms produced with six different stationary phases, it can be seen that columns nos. 1 and 5 (Synergi POLAR RP andXTerra RP18, respectively) can be considered capable of separating the steroid mixture more effectively than the rest. The primary component is very well separated from the secondary component. The other columns shall no longer be considered for further use in method development due to their inability to separate the mixture. 

If one takes a look at the chromatograms recorded with both of the front runners (Figs. 5 and 6), then one can see that as expected with Synergi POLAR RP short gradients and high temperatures have an adverse effect on the separation of the mixture. Those small peaks resulting from late elution give an impression... 

Synergy between polar and nonpolar components is indicated for sex attraction in the larval parasitoid Eriborus terebrans (Ichneumonidae) [58]. Males show several behaviors when exposed to a polar component with chemical... 

Lubricants. A model for the lubrication mechanism has been developed lliat explains synergy between certain lubricants. Tins model neats lubricants as surface-active agents. Some lubricants have polar ends that arc attracted to other polar ends and to polar PVC flow units and to polar metal surfaces. These also have nonpolar ends that are repelled by the polar groups. Synergy happens when nonpolar Lubricants are added, which are attracted to the nonpolar ends and act as a slip layer.

Increased activity of enzymes that make drags more polar is likely to inactivate an antimicrobial drug and will not lead to increased antibacterial activity. Specific examples of mechanisms that do result in synergy include (A) the combination of trimethoprim and sulfamethoxazole (B) the combination of a penicillin and an aminoglycoside and (D) the combination of clavu-lanic acid and amoxicillin. The answer is (C).
