IF2, evolution of Capcell Pak technology in UHPLC columns
Unsurpassed durability against high pressure
|
|
|
Durability is an indispensable quality to columns for ultra-high-speed high-pressure separation. A short lifetime under high pressure, and therefore, a high column cost would make high-pressure separation less attractive to chromatographers.
|
|
|
CAPCELL PAK C
18 IF2 has been developed to overcome such problem with real ruggedness against pressure up to 100 MPa, enabling maximum performance of an ultra-high-speed high-pressure system.

Hydrophobicity and Surface polarity Parameters
|
The graph on the left is the hydrophobicity-surface polarity plot of Capcell Pak columns and other popular ones. IF2 is designed with moderate level for surface polarity and sufficient hydrophobicity, hence thought applicable to high-speed
high-pressure analysis for a wide variety of compounds.

Unsurpassed durability against pressure up to 100 MPa
The graph below shows the durability test measured under a pressure of 70 MPa by adjusting the flow rate of each column. In response to the increase of injection times (x-axis), the durability of each column is plotted at y-axis with the
maintenance percentage of the number of theoretical plate (NTP) of the Naphthalene relative to its NTP at first injection. CAPCELL PAK C
18 IF2 shows unsurpassed durability with almost no decrease in NTP after 600 injections, and is guaranteed for use as a UHPLC column truly ideal for ultra-high-speed high-pressure separation.

Quick and sharp elution of basic compounds
The CAPCELL PAK IF2 showing sharp peaks for basic compounds, provides excellent peak shape and separation efficiency even at ten-time greater flow rate, while enables the analytes to elute quickly.
