mix components. Over the course of the study, the
variation in the peak retention times was 0.08-
0.22% RSD. This includes the polar free fatty acids,
which can be difficult to analyze under ideal condi-
tions. The excellent stability of this stationary phase
is proven by the reproducibility of the retention
times over the course of the water stability study.
The Stabilwax®-DA column is an excellent choice
for the analysis of acids, esters, and other flavor
components in alcoholic beverage products. This
highly stable column has been optimized for the
analysis of acidic compounds, making it possible to
analyze a wide range of compounds in a single
injection. In addition, the column configuration
shown in this article allows fast, efficient separation
of the test compounds. 0 2 4 6 8 10 12 14 16
