Allure™ Acidix HPLC Column - Chromtech.com.au

Restek Advantage, Summer 1999: Allure[TM] Acidix HPLC Column Specialized for LC/MS Analysis of Acids and Amino Acids
However, most of the advantages exhibited by the Allure Acidix are not limited
to LC/MS separations. Fast analyses, excellent peak shape and retention, high
reproducibility, and the elimination of the need for derivatization apply to other
HPLC systems as well. Polar acids (e.g., ascorbic acid) that are difficult to retain
by traditional C18 columns are easily retained by the Allure Acidix phase (Figure
2). Larger molecular weight acidic compounds such as pharmaceuticals also show
excellent retention and peak shape (Figure 3). Additionally, salicylic acid and
aspirin are cleanly and easily separated on the Allure Acidix column (Figure 4).
The Allure Acidix column is a breakthrough in HPLC stationary phase
development that permits the analysis of amino acids without derivatization.
Furthermore, it provides the highest sensitivity available for LC/MS detection of
acidic compounds, and it retains most acids that C18 phases cannot. For samples
with solubility limitations, the Allure Acidix column can be used at both the high
and the low end of percent organic in the mobile phase. Most importantly, it
displays the reproducibility and reliability chromatographers have come to expect
from Restek chromatography products.
