Applications

Phalanx is uniquely suitable for the

efficient analysis of both acidic and basic

analytes. In addition, its high capacity, good

stability at high pH, and fast equilibration

at extreme ranges of hydrophobicity

make Phalanx a powerful option for

challenging separation problems.

 

Phalanx is Higgins Analytical’s latest addition

to a family of unique high performance

HPLC sorbents. The novel end capping

technology of this new sorbent is a

continuation of the pioneering approach

taken in 1996 when we introduced

Targa

®, the first HPLC sorbent

specifically designed for efficient

LC-MS applications without TFA.

 

Based on an ultrapure, Type-B silica backbone,

Phalanx has a relatively high surface

area of 430 m

2/gm, but its very tight

pore size distribution eliminates the

undesirable side effects of micropores

that often plague other high surface

materials.

Optimum for Basic and Acidic compounds:

Many modern HPLC sorbents

employ embedded polar functionality.

While these secondary structures can

provide unique selectivity and eliminate

undesirable solute/sorbent interaction,

they often compromise the useful range

of solutes or buffers that can be used.

The figure on the left and those on page

2 illustrate that Phalanx columns produce

symmetrical peaks during the analysis

of basic, neutral, and acidic compounds.

 

Wide pH operating range: The unique

endcapping reduces acid/base hydrolysis

of the bonded phase and greatly reduces

silica solvation at high pH.
